Hi I am wiring in an fm modulator and am wondering if anyone can tell me what are the wire colors for ground, power, and accesory. The only diagram I can find has the ground as black\blue, and power as grey\red. but I am not sure which wire is the assesory. The only other wire that looks like it has power is the relay starter inhibit grey\orange, which I think keeps power to the radio until a door is opened. Also, on the back of my stereo (non mft or sony) there 2 plugins but only one is used. Does anyone know what the other one if for. Thank you.
