i have a pioneer avh-p3100dvd
i have an amp in my car, and there is no power antenna wire on the 3100 so i have it currently set up as follows
blue (on wiring harness)-power antenna
blue/white(on wiring harness)-amp turn on <=====these are all twisted together into one
blue/white (on receiver) - power amp
now if i take that blue/white cable from the receiver out of the crimp and wire it to a relay wont it not power the amp?
