Wiring diagram
 

Does anyone know where I can find a wiring diagram for a JVC KD-APD89 headunit? Wanting to know what wires are what on the harness.

Im not going to garentee this but im 99% sure this is right. all JCVs ive owned were lil this.

Memory (+12v Constant) Yellow
Ignition (+12v Switched) Red
Ground (-) Black
Power Antenna Blue
Amplifier Turn-on Blue/White

Right Front (+) Gray
Right Front (-) Gray/Black
Left Front (+) White
Left Front (-) White/Black
Right Rear (+) Violet
Right Rear (-) Violet/Black
Left Rear (+) Green
Left Rear (-) Green/Black

EVERY aftermarket headunit is like this

O ok lol. I think pioneer are just a little different tho

:)...

Sweet thanks man!

One more question, I can run two amps off the same amp turn on wire right?

yes just run a jumper wire from 1 amp to the other

Like connect it amp to amp or just the wires on the back of the headunit?

run a remote wire from the head unit to 1 of the amps and then where you connect it to the amp run a jumper from there to the other amp if they are both close or you can run two off the headunit either way it works just easier the other way ... guessing you're running a 4 channel for your mids/highs?
