Looking into this some more for the combination gauges in my truck. I have a few part numbers, see if this jives with anything.
  • 1FZ temp sender is 83420-16040
  • 3F-E, 22R-E, 3VZ temp sender is 83420-16010 (superseeded to 83420-20020)
  • I think the 5VZ temp sender is 83420-16020
So if anyone's done the 50 and 110 ohm resistor mod on a 1991 or 1992 FJ80, then the same modification will work on 22R-E and 3VZ trucks. If the temp sender on Red Chili's engine drives your dash gauge to the same spot as with the old engine, then it's probably got a similar profile. Anyone have an extra 83420-16010 temp sender? We can verify it's response and either do the same values or adjust them slightly to the right profile.
