Hey man, I just went through your whole thread. Nice work on the Montero. I'm really interested in your wiring setup. Primarily your main harness wiring and breaker that you added. I'm planning on adding a higher amperage alternator and want to streamline the power supply. I normally tie the factory harness in to the battery, and then run a nice big 4, 2, or even 0 gauge cable from alternator to the battery. But that's using a GM Style one-wire alternator with internal regulator.
I see some extra leads off your battery setup, is that all for the extra fuse box under the rear seat and power supply? I'm a big electrical safety nut and don't like fire, so I want to make sure i plan out my wiring with the new Alternator properly as well as reducing any bottlenecks, draws, or wastes from the power supply. With winch in the plans, I'll need a serious power supply with little power loss. Winches draw about 300 amps so I'll need to ensure power is clean and free. Any issues with doing new cables on the Montero?
I also make my own battery cables and I've run into a few vehicles that have some oddball splices.
