I have two blue wires.... one comes from the headunit and the other comes from the adapter harness.
The one coming from red adapter harness is on the left (Bottom in my hand) and the one coming from the headunit is on the right (top). Both Remote Amp wires, I just don't know what to do. Do I solder it to HU remote wire and leave the harness wire taped and alone? Or do I connect it to the adapter harness blue wire and leave the headunit wire alone? Or do I connect it to both the HU remote wire and the Adapter Harness wire, making a three wire solder connection?
