I recently switched over from a Sony Head unit to a panasonic one. Me and my friend just switched wire harnesses(undid the connections then reattached to our owns), and now I'm left with a blue/white wire on the deck side of the harness. The car side doesn't have a wire that will match it. The deck side just has a blue and an orange wire left over. I taped it off, and hooked the deck up, but my front left speaker won't work(Yes it did work previously). Now I'm in a pickle, what do I do?
