Fast idle solenoid and timing advance solenoid both have power when the key is in the ON position and the engine temp is below 115 degrees.
The fuel shut off solenoid has power when the key is in the ON position.
Power for all IP connections is supplied by a red green stripe wire, is splits after the chassis to engine harness connector near the dip stick.
After the wire splits, one goes to this switch, then on to the cold start and fast idle solenoids.
The wire changes color at the switch, the wire color out depends on the yaer of the harness.
Very common for the connector to get pulled off the temp switch when working on the glow plugs or alternator.
Then neither the timing advance or fast idle work.
