I have quite a project on my hands, a 1982 Toyota pickup SR5 that spend most it's life as a farm truck in the salt belt. I'm doing a full overhaul of the whole truck. I have a offenhauser intake manifold and weber carb. I'm also rebuilding the wiring harness and trying to make the truck as simplistic as possible. So my question is, what are the sensors so I can order new ones?

 

My diagrams don't go back to 1982 but,

I see a dash temp sender, EGR bmsv, ECT for emissions comp, and temp switch for AC cut off.

None of these have changed much in the 80-90's except maybe the ECT (engine coolant temperature) sensor which went to a two wire sender (since it's important it has the same ground as the computer)
