I am wiring a cd player in my truck is it necessary to get a wire harness that is made for the year make and model of my truck or can I just cut the factory terminals off and just connect the like colors?
While a wiring harness isn't strictly necessary, It's highly recommended. The wiring color code on an aftermarket head unit will match up properly with a vehicle-specific wiring harness. The wire colors of your vehicle wiring will NOT be the same as the wire colors on your aftermarket unit. You have to match the wires up according to function, not according to color.
