swapping a 1991 blazer grill to a 85 truck - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I picked up a nice 85 at the Pigeon Forge Rod runs last week, I would like to swap it over to the 91 Blazer grill! I found this tech article which proved to be of great help!

I found all the parts on LMC to do the swap except for the wiring, I've been told if you can find the blazer harness that plugs into the firewall you can just do a plug and unplug from the truck harness to the blazer harness, (not sure?) and I've been told you need pigtails and splice! I am not really sure what I need to do this, can anyone advise?

You'll also need a new core support. I have one id let go for cheap, and will be in NC in two weeks could meet you somewhere. I considered doing this swap but changed my mind.
