Ah okay, yeah that's what I first thought it to be, a LOC. Well I don't have stock HU, so Il'l rip that out and all it's wires.
And as for the big 3, it's just the way it looks. I did the alternator to the positive, as seen there. Then I grounded the battery and engine block in the same spot, the chassis does go back to the negative battery, and I tested voltage at all wires to ensure it was done correctly.
Thanks for the concern though //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif It's just the pic is a bad angle and the wire goes down from the terminal, not straight across like the stock one.
