I've been picking the web apart trying to find anything on a 0 gauge side mount battery cable (for performing The Big Three) and it seems to be a product that no one makes. I remember hearing that making your own cables usually ended bad, as corrosion from the top of the battery would wick down the cable, which makes every bit of sense, that, and I also can't find a side mount battery terminal end for wire. Everyone makes one for making your own top mount cable, and they make "side-mount adapters" which doesn't seem like that good of an idea based on how close the battery is to the fender, and the lack of a insulator around the top-mount style connector. Does anyone have advice on this, or know where to get 0 Gauge Side Mount cables?

 

Find a battery shop that makes cables for boats. They will have the correct large cable and sidepost ends, and a machine to crimp/press them on. You will probably have to press one end on and fit the cable to your car. Mark the orientation of the other terminal end and then have it crimped. When you're done use some good shrink wrap on the ends (the shop should have that too). You will not be able to twist one of these cables like a stock one, so make sure the ends are lined up correctly.

 

Dumb quesion: what's the big three??

I put a 0 gage battery cable going to my 140A alternator, bought the cable from walmart and a side terminal with the two bolts keeping the cable (not the crimping type) from Pepboys. Sprayed battery terminal protector on it- had it nearly two years no problems (red top optima.)
