I was given an Onstar FMV and am trying to install it. I am unsure of wiring, I was told to splice in to the ignition switch wires and use and the pink and the grey wires. I don't want to pay a mechanic $80 for something I can probably do myself. Though before I attempt anything I would like to know for sure what wires to tap in to before I go splicing in to anything or a better way with out splicing in to the wires on my car.
Thanks!
