    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:
    ? L36 90980-10859 2.3 II m antenna amp
    A L37 90980-12404 0.64 II f
      2CANH=G 3CANL=W
      5SNS2=B 18SGND(nxt 3) 17MACC=R 19MIN+=B 20MIN-=W (mic)
      21CGND(nxt 3) 22V+=R 23V-=B 24CA+=W (camera)
    B L38 \__ component    90980-12552
    C L39 /   tuner        90980-12012
    D L40 90980-12038 1.0 III f / 2.3 II f
      1B=SB 2ILL+=G 11ACC=GR 12ILL-=W-B 13ANT=BE 20GND=BR
      5ATX+=G 15ATX-=R 10SLD(nxt 4) 8R+=G 18R-=B 9L+=R 19L-=W 7MUTE=B
    E L41 90980-12460 0.64 II f
      7SW1=R 8SW2=G (steering switches)
      11IVO+=Y 12IVO-=BR 13SLD(prv 2)
      15ARI=B 16ASGN=W 17ALI=R 18AGND(prv 3) 19AUXI=W
      9TX1+=LG 10TX1-=P (parking assist ECU?)
    F L42 90980-11909 1.0 III f
      1PKB=R 2IG=B 3SPD=V 5REV=P
    G L45 90980-12551

    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).
