Here are a few examples of the electrical shenanigans I was talking about last night:
My glow plug system uses a glow timer (ecu) to control voltage and duration to the glow plugs through the use of two relays, a water temp switch, and a resistor (the sender in the sketch).
I'm trying to translate the voltage flow diagram to something that I can actually use to make a harness with the connections in the right spot.
This is the glow resistor that has the #87 hi-current source from the glow relays.
I'm also working on the circuit for my fuel pumps. As I mentioned, I'm going to use a oil pressure switch to control voltage to the fuel pumps through a relay. Then, I'll use a second 5-pin relay to control which pump will activate based on a dash mounted rocker switch that controls the Pollak switching valve.
The next one I'm working on is the headlight system. The factory FJ40 headlights puts all the current through the headlight switch and turn signal stalk. I'm going to use a pair of relays to keep the draw away from the turn signal stalk.
Step one is to figure out how the original FJ40 headlight switch and turn signal stalk were designed to work... which has not been easy.
