Do you need a wiring harness to hook up a Pioneer radio?

Yes, you need a wirring harness to hook up a Pionner radio on a Honda, because this will provide a standard platform for connecting stereo components of varying brands and models. The wiring will correspond to the leads of the adapter by colors or symbols, matching wiring groups to leads.

Any aftermarket head unit will need some type of wiring harness adapter to make it compatible with the stock speakers.
