Review on 📻 Metra 70-1858 Radio Wiring Harness: Ideal GM 88-05 Harness Solution by Sebastian Erik

I needed this to install a 2 din stereo in an 01 GMC Yukon but the factory amp wouldn't turn on so I couldn't get any sound? I'm thinking that maybe a pin is missing to turn on the amp? Because I did a lot of research before buying everything needed to upgrade the factory radio and it should work without bypassing the factory amp!? I got my new radio working by building a bypass wiring harness, something I wanted to wait for but finally got it working. If it had all the contacts from my factory radio I would give it 5 stars.
