What wire turns on the rear amp?
 

I'm installing an Android that came with the Toyota Harness but it doesn't turn on the amp for the door speakers.


Looks like one wire is missing from the 6 pin and I suspect that is it.


Looks like there are lots of threads about this but I'm just not getting it...

Here's what's on the 6- and 10-pin radio harnesses in my 86:

6-pin connector on back of radio:
Pin 1: Yellow = right rear speaker positive
Pin 2: Purple = left rear speaker positive
Pin 3: Black = right rear speaker negative
Pin 4: Unused
Pin 5: Black with white stripe = Illumination
Pin 6: Pink = left rear speaker negative

10-pin connector on back of radio:
Pin 1: White with blue stripe = front right speaker positive
Pin 2: Black = front left speaker positive
Pin 3: Red = Accessory switched 12V
Pin 4: Orange = Battery constant 12V
Pin 5: Black with blue stripe = front right speaker negative
Pin 6: Yellow = front left speaker negative
Pin 7: Black/blue = Ground
Pin 8: Unused
Pin 9: Brown = Factory amp turn on
Pin 10: Purple = Illumination

Knowing this might help you sort out your problem. Good luck!

Thank You, that made me notice the Toyota harness that came with the radio was missing the turn on wire.


All working now. :thumbsup:
