i had to buy a wiring harness becuase it was chopped off to install an aftermarket cd player (previous owner.) My question is, there are 2 plugs in on the back of the stock cd player...is there supposed to be 2 plug ins plugged in? After installing the new wiring harness I had 3 wires left over: Pink, Purple and Blue. The cd player turns on with lights but doesnt do anything.....help please!??!
