I figured I'd post up my installation of the Big 3 to help the guys out. Its enough I think for everyone to get an idea. I did mine with the plan of having Audio system grounds to the frame. In which I grounded the battery directly to it. Here we go, I will acknowledge a couple things I didn't utilize cuz it was too late...lol (sorta) These will be the areas your going to be workin with when you pop the hood I tried to make my pics user friendly as possible. The first wire I'm doing is the battery to frame ground.(This could be run to the chassis but for good current flow from the back grounds I'm going to the frame directly.) You can run this wire down next to the radiator. UTILIZE the plastic loop that is open on the radiator!! I cut my wire already before I noticed it. 1/0 fits right in it. You may have to put your terminal on after its through there though. Then there is the bumper support bolts that make a perfect ground connection. They're right under the Washer Fluid jug behind the drivers side fog light. Grab your 15mm socket and remove the 3 bolts that hold it on. Easy job except for the damn dirt in your face. Wear goggles...lol Then use whatever tools you got to clean the metal off to make it bare. I used a Dremel but whatever you can come up with will work as long as you get everything off of it. Then do the same thing on the mating face of the support and where the connection will be me made. I used a step bit to make the terminal hole larger to fit the bolt. Gravy. Then just bolt the support back on with your wire connected to it. Make the connection at the battery and your finished with the battery to frame ground. I used KnuKonceptz terminals which have "compression fittings" so not having the terminal on yet was fine but I cut the wire too short to utilize the loop on the radiator. I didn't see it before hand oh well.
