Hey guys. Still working on this 1974 FJ40, tying up loose ends before it leaves the state in a few days. Have to do an FJ60/2F "internally"-regulated alternator conversion to accommodate the FJ60 clutched water pump that I put in, and am running into some trouble with wiring. @Coolerman made me a nice harness to move the wiring to the passenger-top side of the engine and convert from the 3-pin F alternator to the 2-pin 2F unit. He has a good solution whereby one uses the existing "external" regulator as a terminal block.
Problem: I don't have a regulator mounted to the firewall where it should be on a 1974...there's a stub harness on the old alternator which mates to a connector on the main engine harness, and a weird box that I can't figure out. See pics below.
The stub harness on the old alternator:
...engine harness side, mating connector:
...wire colors, engine harness side:
...weird box bolted to driver wheel well:
...the blue wire, butt-spliced to a black wire with a spade connector:
...can you guys help me figure out which wires are which, and where the old regulator is?
TIA!
