I'm using the Tuff Stuff 100 amp one wire from Summit.I got the Ford style as it bolted on my motor plate the easiest.It's not small like the tea cup Denso's,but it works really good.I "upgraded" from a smaller amp Denso alternator as I'm probably going to put the car back on the street later.The 55 amp Denso style I had before worked fine,but I like the higher amp unit better.
