Pretty sure someone here will have the answer I am looking for. I have a 73 FJ40, that I am rewiring and I am working on the gauges. I know what all but two wires are for and they go to the back of the speedometer at the top, one black, the other white.
For the life of me I have not been able to figure them out. Would someone point me in the right direction please? I would surely apprecciate it.

Have an fsm handy?
That white wire is speed input to the emission computer. If you are not running that then it does nothing. There is a reed switch in the speedo that sends pulses to the computer to tell it how fast you are going.
That lower section of the black wire looks chewed up - I think I see copper peaking threw.

Thank you, I appreciate the responses. No FSM unfortunately. It doesnt have continuity through it. A speed input for emissions is not useful to me, so delete in the near future. Pre smog and it has a 305, 700r4 to np205 to centered FJ25 rear diff.
