Hello all, I have a Navigation radio removed from a 2010 Prius. JBL E7022, Toyota part # 86120-47390. I can't seem to find a wiring diagram to locate power and ground to bench test this to make sure it works. Can anyone help? Thanks Kevin
Well, you're welcome to my hastily typed-up notes from one day when I was looking in the wiring diagram. Looks like I wrote them in a [number][circuit]=[color] format, which would mean connector L37 position 2 is the CANH circuit and green, position 3 is CANL and white, and so on. Circuits you could care about for power purposes include B, ACC, and IG, and of course GND. Notes like (nxt 3) or (prv 2) I added on shield drain connections to indicate which circuits run in that shield. Code: ?

Appreciate the help but I still don't understand which two wires I need for 12v / ACC and ground. I can't decode it.
Thanks for your good work. I am in a different situation, I am installing an aftermarket head unit. ( Long Story Short) I am finding RL+ RL- RR+ and RR-. Can you tell me which one has it. I tried to find in L40 but no luck.
I haven't poked at that in a long time, but this is the JBL system with the separate amp. It might be that the R and L pairs shown above (8,18 and 9,19) are all that goes from the head unit to the amp (besides the 5,15 AVC-LAN pair).
