I am going to add aftermarket speakers to the factory head unit. I have taken the door panel off and looked at the speaker connectors. I will have to cut the factory connectors off, and I was wondering if anyone knows the color codes for the factory wiring harness? I don't see any (+) or (-) on the speaker, and the connector looks like both slots are the same size. I know the aftermarket speakers that the small lug is (+) and the big lug is (-).
TIA,
Bill
