I have a 99 blazer and I just bought a new pioneer deh-3400ub head unit. I removed the bezel and everything but now I don't know which wires from the new head unit harness match up with the harness that goes to the battery. Is there anyone that can tell me which wires match up?

 

your best bet is to go get a wire harness from a car audio store or walmart there like 20 bucks and will save hours of cussing

 

I would agree. If you pick up a $20 wiring harness the colors match up to the Pioneer and will take you only a few minutes to install.

 

Thanks a lot It was 18 and change and all I had to do was strip and clamp the wires took me 15 minutes thanks for the help

 

glad i could help and that things went as planned
