Big red is main ISO switch, from left to right, Fuel Pump, Alternator Power, Thermo Fan. As the original wiring of the car was altered when i brought it to run the battery in the boot for some reason the signal wire for the alternator wasnt working so i just wired in a new one with a switch. The custom fuse box runs all the switch power, gauges, thermo power ect, along with running the standard 32 fuse boxes. Rear of car is custom wired by me as I had no normal rear harness.
