I would go with Ron Francis or M&H.I would stay away from the painless wiring .I'm not happy with my painless kit, I wish I would of spent the money on a factory color coded kit.I don't like the painless kit because they don't come in gm factory color codes and it has a bunch of extras that I didn't need.Thank god I save my old harness, I will be slowly replacing everything on it from M&H
