Hi Everybody! I have a 71 GMC Sprint that I've inherited from my father. He never did anything to it other than drive it for the last 25 years, now that I have it I've been upgrading and replacing. It has a 350...mild cam..dressed up with a bunch of Edelbrock stuff...carb, intake ect… The problem I'm having is finding a accurate wiring diagram. I understand they used 3 different ones that year and I can't even find one lol The wiring in the car isn't the prettiest and I'd like to straighten it out. Thanks for any help u may provide
