My 76 Fj40 with stock engine. The guages do not work. the only one that does is the alt one all the others including the illumination lights do not work. But one blinker works. I took the guage cluster out last night and looked at the back. It looks like the previous owner had other wires connected to the individual guages in the back but they actually go to no where. Mine has this plug in the back and I know they go to each individual guage and lights and blinkers. I used the wiring diagram for a 78 fj40 to trace the wire but no luck seem to be different colors to me. There were multiple yellow black wires. I toned all the wires going from the guages to the senders and they tested out ok.
My question is. Is there one common wire that powers the guage cluster? And what color is it. Can I bypass that wire and tap into the guage cluster? Does anyone have a wiring diagram of a 76 FJ40? It's driving me crazy not knowing temp, fuel, and oil.
