Metra 70-5519 Radio Wiring Harness for 2001-2003 Ford Mustang Mach 1 with Amplifier Integration - Perfect for Car Audio Upgrades & Stereo Installations

Metra 70-5519 purchased through Googol. This was exactly what I needed to replace a broken Mach 460 stereo with a Kenwood. The kit has two connectors, one for the radio and one for the amp. The colors matched up exactly to the Kenwood connector wires. My only concern was all the amp ground wires didn't have an equivalent Kenwood wire. But I just connected all the amp grounds with the regular ground and it worked fine. I connected the RCA jacks to the Kenwood SW jacks. The Kenwood has two sets of RCA jacks with one labeled front and the other labeled Rear/SW. Since the Mach 460 has some big subwoofers in the trunk, I figured using the SW jacks is the way to go.It took about an afternoon to wire everything up and it sounded great. What I like about these kits it that you don't have to guess at the wiring or hack up the original wiring. So if I decided to trade-in the car, I can just put the original radio back in and keep the radio for another car.
