[QUOTE="Nevalite, post: 4498405, member: 581408"] Hey guys: I have an Alpine MRP-M850 coming in and I decided to do the big 3 to help out my electrical system a bit. I just need some help making sure I have the right spots. From what I understand I need positive alt to positive battery, negative battery to ground and engine block to ground. I think I have those first 2 but the last one I'm not sure, here's what I've got. This is the positive terminal of the alternator, that I connect to the possitive on the battery, right? [IMG]http://img148.imageshack.us/img148/5329/dsc00710uf1.jpg[/IMG] I need to also add a wire to this negative terminal of my battery and connect it to a ground on the chassis, if I follow one of those wires I should find a ground spot right? (Don't worry im getting new battery terminals :P ) [IMG]http://img135.imageshack.us/img135/7451/dsc00707uc3.jpg[/IMG] Now this last one I have no idea, where do I find the engine block to ground wire? If I follow the second wire from my negative battery terminal will that lead to the engine block? Here's a pic of under the hood, maybe point me in the right direction: [IMG]http://img209.imageshack.us/img209/5047/dsc00711co4.jpg[/IMG] I think the first 2 are right, I'm just not sure where the engine block to ground is.
