Ok so most of the wiring in my 76 k5 is old and needs replaced. Now I can just buy a few spools of wire and go to town replacing stuff or I can buy one of the Painless wiring harnesses. Has anyone use one of these before? How well did it work for you? It's for a pretty much trail only rig but needs to stay street legal. I was thinking of doing the 12 circuit universal one, now I'm wondering if I want to get rid of the dash and do a push button start or get the colum adapter.
