I've had so many requests from members here to join that I am here now! If anybody is interested in a factory style full plug n play 4-HI upgrade harness, here is a pic of what I offer currently. I build a vast line of restoration quality harnesses for 73-87 trucks and I build full time both stock and build to suit harnesses. These 4-HI kits have become popular enough on the 47-present forum that I'm typically 2-3 days before shipping since I can't keep them in stock lol. These are not complicated to build on your own but if you want a stout factory style upgrade, this is it.
