I'm probably going to do the dual battery setup eventually. But where are people running the power cables into the cabin? I installed a ham radio in mine and ran the 10 gauge cables through a small tube (had to cut off a small rubber nipple on the engine compartment side) that is part of the big rubber grommet that holds the main wiring harness. It was a tight fit and it took a lot of work to get it through.
There seems to be another rubber grommet that is a bit higher than the wiring harness one, but on the other side, it looks like it would hit the firewall.
On the passenger side, the one grommet looks like it comes out behind the glove box which would block the wires.
Also, how are people running wire under the shifter to the console?
Any suggestions on location would be appreciated!
