has anyone ever had a problem with an aftermarket radio in there dakota, i have the premium system which has a purple/yellow stripped wire that connects into the central timing module, when you hook up an aftermarket radio there are no connectors that use this wire, without it hooked up my wiper blades will not shut off, the locks dont work on the doors, the dodge dealership told me that the wire needed to be plugged in is there anyway to bypass it?
