okay, do you have a multimeter? you have a constant 12+ and a negative. to test 12+ use negative probe and connect to bare clean metal. use positive probe and touch each wire. once you find 12+ keep on the 12+ with your probe and use your negative probe to find ground. there is a input that will only sense when the radio comes on. im guessing its a positive. get a friend to turn your radio on. and probe one wire. no signal then its not it. try it all over. not sure of the rest but i will try to stop by the shop and look it up. what does it say the wires are for on the antenna instructions or guide?
