I am putting the original radio back in my GN today. The problem is that I have the Black/White/Blue connectors and the Yellow connector which all seems correct, BUT there another wire that is actually 4 wires glued together from the factory. They do not go to any of the connectors. These have been spliced directly into the wiring harness for the aftermarket stereo and I can't seem to figure out where they go for the factory radio? The wires are bule,light blue, yellow, and brown. Am I missing the connector for a harness or where do these go? Thanks -----Jeremy
