I have two 94 blazers. One is normal, and everything in the manuals goes smoothly. The other one, the one I really like and am working on getting just right, is a blazer SPORT model. I bought a harness kit for the radio, to upgrade it to an aftermarket unit. However when I pulled it apart, the wiring is completely different from my other blazer, and every 1500 i've ever seen in the year range. This one has an amplifier, tape deck, and stock radio setup. Now stupid me, I dont need the old stuff, so I cut wires to make it easier. So right now I'm running without a radio.

Is there a different wiring harness I should have bought? Or am I stuck rewiring everything according to my new head unit?

 

all set, just found out the wiring harness i was looking for was tucked up in the top and much shorter than the other blazer's harness. It was attached to the top of the amp way up under there. All good now.
