I got new OEM replacement terminals meant for an Avalon from around the same vintage:
90982-06022
90982-05035

Then, I made a custom buss bar to run off the positive terminal (copper bar, bend and drilled):




It has:
Headlight harness
Offroad light harness
Trailer brake and charge (on breakers)
Winch (also on breakers, but can easily be bypassed if needed)

It is wrapped with both heat shrink and silicone fusing tape for protection.

The ground side just has the engine, fender and winch connections. Charge wire, ground wires, etc are routed as OEM but all 4 gauge. Alternator is a 105 amp Denso from a Grand Vitara.
