'95 S10 Blazer. The Delco radio finally died, got an after market along with an install kit and new speakers.

Installed it, was a little tight but it works, the dash lights don't. Have (2) wires left over from the wiring harness, one goes to 12 volts when the headlight comes on, the other wire is a light color, maybe a buff color that is a ground. Did use the 12 volt battery, 12 volt ignition and ground. Everything else works like it's supposed to. Fuese are all good.

Thoughts, ideas? Getting so I can have the dash bezel off and the radio out in about 10 minutes.

 

Currently installing an aftermarket radio into my 95. Did you have a wiring harness, or did you cut and spice the wires? I haven't noticed any problems with mine

Now that I think about it, though. I've never turned the headlights on, so I don't know if the dash lights work lol

 

Original wiring harness came to a plug with (5) wires. 12 Volts battery, 12 volts ignition, Dash lights, ground and another ground. Radio input only needs 12 volt batter, 12 volts ignition and a ground. I cut the original plug off and spliced the wiring harness that came with the new radio to the original power harness. I did run new wires to the new speakers.

Everything works except the dash lights and the warning buzzer that tells you that you left the headlights on. Buzzer does work, it reminds you that the keys are in the ignition.

 

There's a lot more than five wires in there. This is my factory wiring


My radio came from a friend, and already had a factory harness adapter. I soldered that to the radios harness:


It's completely plug and play. I retained the factory harness, dash lights and buzzers work.

Those adapters are super cheap, and the colors match that of the radios wires, making it very easy to hook up.

Any way you could put the factory harness back together, and get an adapter?

 

The black plug which is power is the one I was referring to. The other 2 plugs are for the speakers.

Yes, have the factory plug, I cut the wires long enough so I could splice them back if needed. Just left the speaker wires and plugs, ran new wire as I suspect that a short in one of them was the cause of the radio failing.

 

Fixed it.

Seems the switch was bad.....
