Review on Metra 70-5603 Amplifier Integration Harness: Enhanced Compatibility with Ford Vehicle Models by Roel Lebron

I bought this harness to install a secondary receiver on a 1995 Ford Ranger with a Ford Premium audio system. Works great for me, just plugged into the pre out jacks on a new stereo and plugged the jack into the factory wiring harness. I connected the black shield ground wire to the ground of the backup power connector. The wiring harness easily integrated the factory amp into my setup and avoided using a bypass amp harness to connect my speakers to my new stereo. Excellent goods!
