I'm replacing the failed OEM power antenna with an aftermarket one. and as the new one uses two wires 12v, and radio switched 12v for a trigger, I'm wondering if anyone knows the correct color wire to use for the trigger. There are a lot more than two wires at the OEM antenna harness plug and I want to be sure I use the correct one for the trigger. I found the 12v constant, but a couple of wires go hot when the radio is turned on. Can anyone help. Thanks
