Yeah going to have Vintage Air, Fans, Killer sound system, 440 RB 240 TF heads and so forth. With a 3 wire set up and no altmeter would I still need to run a wire form the alternator to the starter to pull some of the juice off of the factory harness. Yeah If I have to pay the extra $$$ that's fine I just want my electrical system working right and safe. Getting the correct mounting brackets and pulleys to work with the AC is a big plus also lol. Thanks!
