Pinout diagram for head unit connectors on Toyota cars

Nowadays, almost every car has an audio system that requires proper connection and installation. Most drivers replace the standard tape recorder with new ones purchased separately. As a rule, to connect them, you need to have some knowledge in the field of pinout of radio tape recorders, namely, connectors for connecting them. Without this knowledge, you can not only damage the player, but also burn several fuses of the car itself, since the system may be connected incorrectly - system short-circuits are not a rare case of self-connection.

In this article we will talk about the pinout of Toyota Corolla radios, and also present a visual diagram and try to describe it. In fact, there is nothing complicated or dangerous in the connection process, you just need to know where which wires should go.

Ways out of situations with player pinouts

Let's look at both options. The first option is the simplest - today in the automotive spare parts market, in particular the sale of audio systems for cars, there are many different adapters for all kinds of radios, where on one side there is a standard connector for the Toyota Corolla, and on the other side there will be a connector designed for your player. You can see what the adapters look like in the photo below.

In this option, in order to install a new system in your car, we buy:

• Player;
• A special adapter that adapts it to your car.

In the end, all we have to do is put everything in its place and enjoy it to our health.

The second option involves independently connecting the player’s contacts to the connectors of your car. This option is suitable for people who could not find a similar adapter, or for people who want to understand in detail the process of connecting a new device to their car.

Before connecting, let's look at what the input sockets for the radio in a Toyota Coroll look like. You can see them in the picture below.

There are similar holes on the player itself. In order to independently connect these connectors with wires, you need to know the pinout of the radio - that is, know what each wire is responsible for, and also know the pinout of the input holes in the car itself. We will not talk about the radio, since depending on the manufacturer of the radio, the pinout options also change. For example, SONY has its own pinout, and Pioneer has its own. Typically, the installation and use instructions contain a detailed diagram describing what each wire is for. If you don’t have a manual, you can find these diagrams on the Internet - today they are quite common.

Having talked about the radio, let's talk about the pinout of the sockets on the car itself. The picture below will show a diagram, below which you will find a detailed description of what each contact is needed for. So let's get started.

We see a diagram - it makes no sense to consider it without a description, since each number has its own designation, and incorrectly connecting the wires will simply lead to a short circuit. Therefore, the wires should be connected strictly in accordance with their intended purpose - if it is a permanent plus, then it should be connected to the hole where the permanent plus is located, etc. I hope the principle is clear to you. So let's look at the meaning of each number.

1. This number designates the 12V wire that serves as a conductor when the ignition key is turned to the ACC position;
2. This number serves as the same 12V current conductor, only in ignition mode;
3. The third number indicates the front left speaker with the value “+”;
4. The fourth number represents the front right speaker with the value "+";
5. This connector remains unused;
6. We also do not use this connector; it should remain empty;
7. Number seven – antenna power supply;
8. Grounding - the use of this connector is mandatory - this is for those who consider it not a first necessity;
9. The ninth number is the front left speaker with the value “-”;
10. The tenth number is the front right speaker with the value “-”;
11. Rear left speaker “+”;
12. Rear right speaker “+”;
13. Rear left speaker “-”;
14. We do not connect;
15. We do not connect;
16. Rear right speaker "-".

Connecting a Toyota car radio at home: simple circuits

In order for the audio system to produce the highest quality sound, it must first be connected correctly. Making mistakes during installation can lead not only to poor sound quality, but also to malfunctions of the head unit as a whole. For more information about the pinout of the radio on a Toyota car and what system connection diagrams exist, read below.

Several connection schemes

Pinout of toyota car radio connectors

It is believed that the main mistake when connecting Toyota car radios is pulling the positive wire from the cigarette lighter. This will in no way have any effect, since the power of the head unit will drop several times (this is easy to verify if you pay attention to the flashing backlight while the device is operating at high volume). In addition, connecting Toyota car radios through the cigarette lighter will not eliminate sound distortion, which will begin to appear noticeably earlier. On the other hand, in some cases this option may be considered suitable for implementation. The ideal option for connecting Toyota car radios, as well as all others, is to provide the main power supply from the battery. It is advisable to use high-quality wire (it is in no case recommended to skimp on the cable) and be sure to use a fuse, which must be placed as close to the battery as possible.

Note. Let us note right away that car radios have not one, but two power wires. As a rule, yellow is responsible for the main power, red for control (goes to the lock).

In addition, the pinout of the remaining wires:

• N* – negative wire. They are usually connected to the car body, providing ground. However, it is recommended by experts to connect it to a battery;
• C is the wire that is responsible for the amplifier or active antenna.

In addition, the car radio is also equipped with speaker wires (they go to the rear and front speakers):

• B, C-th – wires for front speakers;
• Z, F – wires for rear speakers.

Note. You also need to know that each pair of acoustic wiring contains additional monotonic and negative wires. The latter is often marked with a black stripe over the main color.

Connection according to diagram 1

Connectors for car radios

• We connect the power wires to each other;
• We connect them to the battery.

The good thing about this scheme is that it is easy to implement. On the other hand, it is only suitable for car radios with low power consumption. If you connect a powerful device according to this scheme, then in just 2-3 days in sleep mode the car radio will completely discharge the battery.

Connection diagram 2

This circuit is suitable for any powerful car radio:

• We connect the power wires to each other;
• We connect them to the battery;
• We install an additional button (it is responsible for turning the device on and off).

This scheme involves manual control of the radio, but the settings will not go wrong and the battery will not run out in a couple of days.

Individual scheme, implying the following:

• We connect the main power wire (yellow) to 12 V;
• We connect the additional one (red) to the side lights (via a relay, the winding of which is connected to the ashtray light bulb).

This scheme provides the following advantages:

• The device turns on simultaneously with the “dimensions” automatically;
• The driver will never forget to turn off the side lights and headlights;
• While stopping, you can listen to music without turning on the ignition;
• If you replace conventional small bulbs with LED ones, the electricity consumption will be very low.

Adapters for different connectors

The elements are designed to connect the car radio to the car's electrical network using various plugs. Often, adapters are equipped with ISO connectors on one side, and on the other, a non-standard proprietary connector suitable for a particular car model.

Using such elements, you can mount speaker systems with Euro connectors instead of devices with original plugs, and there is no need to re-solder the conductors or any other intervention in the machine’s electrical network. On sale you can find products with 2 non-standard plugs.

Sometimes the car is not equipped with connectors, then you need to connect the plug suitable for the radio to the wires in the car. This is done both by twisting and soldering. A terminal block is also used for this purpose; additional insulation is not needed in this case. When twisting and soldering, you will have to use cambrics or heat-shrink tubing to ensure safe use of the device.

Adapters are used to connect:

• nutrition;
• antennas;
• radio;
• sound.

The advantage of using the elements is that there is no interference with standard wiring: the user does not have to solder or cut wires.

On devices with the option of control from the steering wheel of the car, a button adapter is provided - another type of adapter. It is a special device with which you can replace the standard audio system with other equipment.

Connecting the camera according to the pinout

Knowing the pinout of the car radio, you can easily connect the rear view camera with your own hands. Using the example of the popular Toyota Ca-Fi device, we will learn how to do this. The process itself is divided into two parts: the actual installation of the device with the connection and the connection of the rear view camera.

Note. Installing and connecting the monitor is no different from installing the factory head unit. You just need to swap the connectors and that's it.

But connecting the camera can be difficult for some. Here's what you need to know:

• The rear view camera for Toyota Prado is powered by 5V;
• To connect it, you will need a connector from the factory monitor, which remains free after installing the new radio;
• This same connector is 14-pin. But we only need two video signal wires and a reverse signal;
• In addition, you will need to convert the voltage from 12V to 5V.

Note. To convert voltage means to carry out the process using a special converter, which is sold in any store.

The camera connection diagram has its own pinout. This is what she looks like.

The circuit is positioned as if you were looking at it from the side of the wires. The photo in the upper left corner is placed for clarity. So, in order to connect the camera to the Toyota car radio, you must first connect together the reverse signal and the Reverse wire on Ca-Fi. In addition, it will be necessary to install a converter and make a tulip for transmitting video data.

Note. This does not mean that you will have to literally do everything from scratch. You just need to buy Scotchlocks in the same store where you purchased the converter (they will help connect the wires to each other).

The photo below shows how to splice wires using tape.

Scotchlock and wires

Next we do the following:

• We start the car;
• We turn on reverse gear;
• Let's check how everything works (the monitor of the installed radio should show the image from the camera).

Thus, knowing the pinout of Toyota car radios, you can connect using any of the selected schemes. During the work process, it is extremely useful to watch a video review. Step-by-step instructions from other sources will also help. The price of installing a car radio yourself is noticeably different from the cost of specialist services, which is several times higher.

Very often, users have a question about how to connect a Toyota Corolla radio themselves and whether it is possible to do this information at all. Many people believe that connecting a Toyota Corolla radio correctly is too difficult and therefore turn to specialized centers, which brings unexpected costs.

Toyota Corolla radio

It is worth noting that Japanese cars, including Toyota 86120-60581, are crammed to the brim with electronics, which often confuses many Russians. In this case, the standard factory-type radio is replaced with a more modern one or connected quite quickly and does not require much experience in this area.

Replacing a car radio: instructions

Replacement should only be carried out with the car engine turned off. In addition, you need to make sure that the future equipment is the correct size.

To replace this device, you need to prepare the following tools:

• screwdriver;
• connection diagram for gu teyes on Prado 120;
• pliers;
• Euro ISO connector adapter.

Now you can start replacing.

The first step is to remove the old device. This procedure is performed like this:

Carefully dismantle the front panel, it is important not to damage the casing. Then we unscrew the screws that attach the product to the body. We put all the unscrewed bolts in a separate box so as not to lose them. Now you need to remove the device from the socket by pulling it towards you. After this, you need to disconnect all connectors from the power supply. We have removed the device, now you can start connecting the Prado 120 radio with an 8-inch touch screen

We have removed the device, now you can start connecting the Prado 120 radio with an 8-inch touch screen.

The connection diagram for the Tesla Prado 150 radio is below.

The connection occurs as follows:

1. Using an ISO Euro connector, we connect the positively charged terminal and then the negatively charged terminal.
2. We connect the car antenna.
3. We insert the body into the frame, the frame into the panel.
4. We secure it with screws.

This completes the replacement of the Toyota Prado steering radio. Now you need to check its functionality. To do this, you need to turn on the radio or other audio player.

How to properly connect the factory radio of a Toyota Corolla

In order to connect the standard Toyota Corolla radio, it is worth understanding the reasons why the device is being changed.

The fact is that the proprietary Japanese version upsets many because:

• has a crooked FM range;
• reads CDs that were not purchased from company stores rather poorly;
• can shoot CDs quite far;
• The disk reading function in MP 3 mode is completely absent;
• does not accept the flash drive;
• there is a TV available, but it often does not work;
• navigation has maps of Japan or does not work at all;
• inability to repair equipment.

Connecting the Toyota Corolla radio correctly will be much easier than connecting a huge number of wires to connect the MP 3 player. However, it would be better to replace the standard radio from the Japanese manufacturer with a European version for the Toyota Corolla, which can play high-quality video and audio files.

So, connecting the radio to Toyota 86120-60581 is done in stages:

How to connect AUKS to a Toyota standard radio

Often, motorists try to connect AUKS to the standard Toyota radio in order to make the most of all their capabilities. It is worth noting that the AUKS for Toyota Starlet 56037 is a connector for connecting digital media to it, including a flash drive, MP-3 player, mobile phone or tablet.

In order to connect a Toyota AUKS to the radio, you should perform a number of simple steps:

• remove the Toyota Corolla decorative panel;
• disconnect the rear window heating connector;
• remove the gearbox by disconnecting its wires and the ashtray;
• pull out the head unit;
• completely disconnect the connectors and antenna;
• disassemble the receiver housing;
• disconnect the cables;
• After that, to connect the AUKS, you need to solder the wiring to the board.

In order for the AUCS to work correctly, it is necessary to correctly pinout:

1. yellow and red wires are needed for channels;
2. the black wire is connected to the negative or ground;
3. The following should be soldered to the board:

• RCH – red;
• LCH – yellow;
• GND – black.

AUX connection

After this, all wires should be routed through a special hole and connected to the radio. The cable is easily routed through the glove compartment, after which the receiver can be assembled and tested by connecting a phone or flash drive to the AUX cable.
