Ok here they are, I did have access to them:rolleyes: I Hope this helps.

That should help Good job Mike!

i need to rewire the lights, and all ground wires. so i figured i would just do all the wires.. but the most important is the lights and tail lights, thank you sooooo much, i will download them soon. and get to work....

You got it, its amazing how simple yours is compared to the newer computer controlled vehicles. It should be an easy fun project.:cool: Just use the same colors when your replacing the wires, keeps mechanics happy, less confused & follows the stock diagrams ;) Your lights are on the second PDF

1979 Blazer K5 Cheyenne, Trailering Special
 

I have a 30' camper trailer with a different type plug-in then I have on my Blazer. I'm looking for the wiring diagram for the plug-in on my Blazer and was wondering if anyone here might know where to find them.

I checked the previously posted wiring diagrams and didn't see anything in there about wiring for the trailer light plug-in.

Thanks Mike! The brake lights and turn signals on my '72 are finally working again with help from those diagrams.
