Under the rubber cover is the 175 amp fuse that goes between the alt and the started relay supplied with the alt when you order it. Other than replacing the stock wire with this, it's pretty much just un-bolting the stock one and replacing it with the higher amp one. I did buy the smaller pulley from him to increase the amperage because it spins faster at idle which is good when you're crawling and using accessories at the same time....
