Has anyone ever done the "BIG 3" on a 97 BMW 3 series? ?

See, I always tell everyone that a capacitor won't do anything, but no one listens. lol. Anyway, you HAVE to run a cable from the alt to battery positive. It's part of the Big 3 and if you want it to work you'll have to do it. I know it's expensive, I hate buying cable. lol Good luck!
