I plan on installing an aftermarket headunit. I know where all the wires go except two. They are both short and blue. One is (Blue) Motor Antenna Relay Control Lead and the other one is (Blue with a white stripe) External Amplifier Control Power Lead. I think there is an amplified antenna feed on the C2 harness does one of these wires get connected to it? or is these wires only for an external amp. Also do I need to do anything with the can bus wires? Will I lose any functions? I do not have the infinity system or no external amp.

 

as far as i know.. if you arent installing an aftermarket amp (which it doesnt sound like you are, maybe you are though??) you shouldnt need to worry about those two. the solid blue one, for the motor antenna relay is for a motorized antenna (sends it a signal to turn on, basically - - we dont need that for our antenna, obviously) and the blue/white one does the same(sends a signal telling it to turn on), but for an amp.

At least this is what i plan on doing when in install mine next week.. If im wrong someone else say so cause i'd like to know
