Lights and wiring!
This was a huge undertaking, I have a ton of lights and electrical equipment.
I installed the stock battery out of the 4Runner, for the time being.
I picked up a stainless steel box for free, so I used it as my electrical control box. Here is the front of the control box; switches w/ waterproof boots, indicator lights, shore plug and digital voltmeter.
Shore plug in use, it connects to the batter charger/maintainer
