Aftermarket stereo installation?
Why purchase the aftermarket wire harness? Installation is easier, no guess work with wire color codes and a Headache Saver!Factory wire colors codes are not universal. See Aftermarket Videos above.
We discourage cutting the factory wire harness.
This section aids in troubleshooting and determining wire color codes, phasing for speaker hook up, locating power wires for installing external devices and add-ons.

IMPORTANT - There are two (2) yellow*, two (2) gray and two (2)
brown wires in this harness. Locate the +12 volt constant wire first.
Label it or splice to constant wire on aftermarket stereo first. Swapping
yellow wires will cause damage to any aftermarket stereo. Check fuses if your unable to find +12 volts.
