DO NOT CUT FACTORY WIRE HARNESS
   
Aftermarket stereo installation? Purchase the aftermarket wire harness! This makes the installation easier, does away with improper speaker phasing and can save a headache. We discourage cutting the wire harness.
This section of our website is to help you locate power wires when installing external add-ons and extras. We hope this section of our site is helpful.
