unless you known what each wire does get the wiring harness or you very well may destroy your head unit
You should always use a wiring harness to install a stereo in a vehicle. Cutting the wires and attempting to hand wire is almost always a bad idea. The wiring harness is pretty cheap ($10-$20) and simplifies the whole procedure. Most of the time, the wiring harness and the head unit have similar colored wiring to aid in quick connections. Also, and more importantly, you can reverse the installation. The plugs will still be there and no cutting and rewiring at all. Remember, the head unit costs $150-$250 bucks, why would you cut corners on the installation kit?
