It is called a "fuse" junction block but I don't see anything about it that would appear to serve the purpose of a fuse. I had a starter go bad on me. I replaced the starter and all seemed fine but now I get nothing other than a single click sound and lose power to the cab. The link I shared above mentions "Once installed all of your cars power runs through this connector. Your car will notrun c orrectly without this item."
