Depends on how old the unit is. The new one will come with a new wiring harness.

...as long as you buy another pioneer...i know its common sence but i had to through that in. sometimes companies will change a wire or two or add another wire for something. as long as it fits and its pioneer to pioneer you'll be fine. if you buy an kenwwood or alpine and it fits it prob will smoke a little too...
