[Electric Land Cruiser]

IMO the wiring part of an EV conversion is the easy part, ie "connecting" everything. Just follow the wiring diagrams of the components you buy. Getting the mechanics working; powering the wheels and building a box for the batteries are the hard parts.

I think a Wrangler is an awesome starting vehicle for the conversion. Depending on what transmission it has I would either direct drive into the transfer case or maintain a manual transmission for extra ratios off-road.
