DON'T REMOVE FACTRORY CONNECTORS!!!!!!!!!!!!!! Spend $15 and buy a wiring kit. It plugs right into your vechile wires and the kit tells you what wires are what. Splicing the wires will lead to headaces down the road!!!

I dont understand why you would need that unless you took off all the wires and took out all the plugs and forgot how the wires were.I have the same truck and I always do the plugs and wires one at time to make sure I make a mistake.If this is your ploblem let me know because i might be able to walk you though it.

If it is the factory Delco/GM radio, should work something like this.

Turn the truck on (does'nt have to be running just accesories on), turn the radio power off (turn volume knob all the way left till off, or power button off depending on the radio). I believe there are two buttons on the front next to each other, seek/scan maybe? Press and hold to change the time. One does hours, one does minutes.

if you know the firing order, then get #1 on TDC, and then take the cap off, the rotor should be pointing forward, thats where number 1 wire should go.
