I have a 2007 ES350 w/ Nav, non-ML, and would like to know if anyone here can tell me which wire on the factory amp can be used for remote accessory.

I've searched CL, googled and googled, I found a few diagrams, but none identically matched my car. I found a few posts that say to use the gray wire. Problem is, there are two gray wires, one on each end.

I am installing an aftermarket mono-amp for a subwoofer and just need to know which wire to tap.

Thank you!

 

just use an ACC wire.. doesnt have to be from the radio..
