Howdy Chris - Yes, all of the holes are for the cables. I will post a photo of the box with cables installed soon. There are 5 holes for the 5 cables running to the front of the vehicle: 1 shared ground cable that connects at the starter/trans/engine (4/0), 1 aux battery cable that runs to the power interrupt mounted by the isolator (4/0, for the winch), 1 main battery cable (1/0) that runs directly to the starter (B terminal), and 2 charging cables (2 gauge) that run from the isolator to each battery. The charging cables are smaller diameter. So I ran them through 3/4" conduit. The larger cables required 1" conduit. I also have 2 holes in the rear of the box. I'm planning to install a quick-connect terminal at the rear bumper (area), which will draw from the aux battery. That will provide access to power at the rear for running a cooler, compressor or giving someone a jump start. Lastly, the box between the batteries is a 150 amp circuit breaker for the main battery. That will act as a fuse on the main, should something go awry. But I like the idea using a breaker, being that you can reset it and go instead of hunting for a spare fuse... <img src="/forums/images/graemlins/kewl.gif" alt="" />

Regarding the jack, I have a Hi-Lift jack that will be mounted on the rear bumper. The factory jack won't reach the frame unless I boost it with some blocks. So a farm-style jack mounted outside will have to suffice... <img src="/forums/images/graemlins/evil.gif" alt="" />
