90 temp sensor wiring

[no1of consequence]

leif,

the sensor controls a few things, the temp gauge, the dash auto-check
system, and an ac switch. i just had to rewire mine as the plug
disintegrated.

from the bentley for 80/90/cq:

1T = BL/BR
2/R = BL/W
4C = BL/Y
3/+ = BK/BL


lead identification on the thermoswitch:

---------------------|
  T          R  |
  +           C |
---------^------------|

+  carries plus voltage from terminal 15a
C sends signal to overheat warning light above 120 C
R goes to a/c safety switch
T  sends signal to coolant temperature gauge.

hope that helps,

-jim
