ive used american autowire before on C2 and C3 corvettes. very good product ive found. they are restoration quality and not meant for extra stuff. however i just tore a brand new one apart for a C2 to incorporate all the things added to the engine bay area. ive got the wrap they use for the harness too, so after adding what i needed i made it look stock again. well its a lot fatter, but it looks great. they make a great product, but it may not be right for you. just depends on how many changes youve made over factory
