Do you have to buy a wiring harness for an aftermarket radio?
Whether you’re installing a new stereo, swapping out your air conditioner compressor, or just replacing a set of speakers, you’ll likely find yourself in need of a wiring harness. These simple devices make it easier to connect new electrical components to the factory-installed wiring in your car.
Are all aftermarket wiring harnesses the same?
For the most part, the wiring colors on aftermarket stereos and these adapter harnesses are standardized. That wasn’t always the case, but these days you can pretty much count on the red wire being switched power and the white wire being the positive lead for the front left speaker.
