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)
