Yeah this is how the one you are talkin about was set up -

I bought a kit off ebay and it was just one piece for the diode/regulator but I also had an ebay brand 180a alternator as well. Unfortunately I didnt take pics back when I had my buick. I'm gonna have to tear down my 03's stock 105amp in a few months and Ill definitely take pics of that.
