On my M725, it was partially converted to 12v, so I looked at the wiring harness to see if it was salvageable, and alas, it was not. It has a 12v 350 in it, and whoever did the conversion hacked it up electrically. There was a 24v generator hooked to most of the lights and a 12v alternator running the ignition on the engine.
My plan is to wire it myself, and I have puzzled myself into a fit.....
That said, I am building a loom, and I may be overthinking it, but heres my question(s):
Turn relay box: There isn't one, the previous owner has a simple three way relay with 5 outputs: indicator lamps on the turn lever, 2 left and 2 right. For the sake of not confusing myself, I'm going to use these terms: Tail light (normal, light is on), brake light and turn signal.
My question is assuming the switch is in the "Service Drive" position.
Looking at the diagram (I've included it as a photo for reference and a .pdf of you want a clearer image to download):
:
On my truck, power is sent to the tail lights via wire 21 to the taillights. I have power going to my turn relay with wire 467. I have already wired in the turn signals (22-460-461) to flash at the appropriate time with the taillights on. My issue is brake light signal. Based on what I see, when I apply my brakes, power will flow from wire 75, through the hydraulic switch, then back to 75A through wire 22, where in the schematic it goes to the relay box to activate the "Stop" side of the STOP/TURN function. I don't have the relay box, so how would I wire this to allow the brake function to work, but be interrupted by the "TURN" function?
