    Perfect!

    Makes installing aftermarket stereos a breeze! I used this harness in my 1990 S-10 and it was a perfect fit. It even allowed me to make connections for my nighttime dimming when the headlights are on. You definitely need to read the instructions thoroughly to make sure you don’t make a wrong connection but this was worth every penny!

    Easy Install

    Upon recommendation from my local BB Car Audio Install Dept., this made it so easy to upgrade my old S-10 Blazer Radio to something more modern. The color coding matched 100% with the old and the new. It was so easy that I couldn't believe it.

    Best Buy installed my stereo for free. I didn’t do anything myself. I just bought a $99.00 JVC stereo, the harness and they put them both in for free.They also showed me everything about how it works. Very satisfied.
