Toyota Radio Information
Ok, Hopefully this will help everyone see how Toyota Radio’s work and what you can do to install different radios in your Toyota. This will be a rather long post and I’ve been known to leave out information that seems important to some people, so please try to understand what I think is implied.

There are basically 2 types of Toyota Stereos:
1. Internally Amplified (the amplifier is in the Stereo)
2. Externally Amplified (the amplifier is a separate component)

For the Internally Amplified Stereos I’m only going to discuss the most common type which is the 10pin 6pin Stereo.


10pin 6pin
This set up is pretty much used on almost all Toyota cars except for the upper end models. You will find many different 10pin 6pin type stereos, they are available in a single din or double din sizes and different combinations of drives.
The back of a Toyota 10pin 6pin radio looks like this.


The connections you should be looking at are the ones Labeled 10pin and 6pin, I will discuss the 12pin connection later.

Here is the wiring pin out of the 10pin connector:

1: FR+
2: FL+
3: ACC
4: +B
5: FR-
6: FL-
7: GND
8: ANT+
9: AMP+
10: ILL+

Here is the 6pin connector pinout

1: RR+
2: RL+
3: RR-
4: (usually unused)
5: LL-
6: RL-

Here is a picture of the connectors that plug into the 10pin 6pin Stereo


Now, if you were going to install a aftermarket radio into a car that has the above 10pin 6pin connectors you would wire these connectors into your aftermarket radio to plug into the above connectors (they mimic the back of a 10pin 6pin stereo)

Next is the 14pin Externally amplified Stereo
Here is a picture of the back of a 14pin stereo


And here is a picture of the 14pin connector that plugs into the 14 pin radio

Here is the pinout of the 14pin connector

1:AMP
2:ILL+
3:+B
4:MUTE
5:FL
6:FR
7:ANT
8:LL-
9:ACC
10:GND (SLD)
11:SGND (FADE)
12:BEEP
13:RL
14:RR



Next is the 15pin Externally amplified Stereo
Here is a picture of the 15pin connector on the back of a 15pin Stereo


And here is a picture of the connector that plugs into the 15pin stereo


Here is the pinout of the 15 pin

1: AMP
2: ILL+
3: ACC
4: +B
5: MUTE
6: FL
7: FR
8: ANT
9: LL-
10: (normally unused)
11: GND (SLD)
12: FADE
13: BEEP
14: RL
15: RR

You can easily add a aftermarket head unit and continue to use the Factory amplifier.
You will need to buy a “Toyota amplifier integration harness”
I think it is made by Metra and the part number is 70-8112
It looks like this


Next is the 20pin Externally amplified Stereo
Here is a picture of the 20pin connector on the back of a 20pin stereo


Here is a picture of the 20pin connector that plugs into the stereo


Here is the pinout of a 20pin

1: +B - yellow /blue
2: ILL+ Dark Green
3: AMP Red
4-6 (typically unused)
7: MUTE Brown
8: FR Black
9: FL Blue
10: GND (SLD) - Silver Wire
11: ACC - Gray
12: LL- White/ Light Blue
13: ANT+ Pink / Blue
14, 15: (typically unused)
16: FADE - White
17: BEEP - Red
18: RR - Light Green
19: RL - Yellow
20: GND (ground to chasis) - Brown

The 20pin externally amplified system can also use a Amplifier integration Harness
I believe it is made by “Metra” and the part number is 70-8113
