1990 Mighty Max - Overdrive In/Out

[pennyman1]

The temp sensor is located on the intake in front of the throttle body. it is a one terminal sensor. It delays the availability of o/d to when the truck is up to operating temperature. It is an emissions thing and is not necessary. There may be 2 sensors near each other in the same location - one is the gauge sensor and the other is the o/d sensor. both have black wires, but one should have a white tracer - that is the gauge sensor. There should be a spot on the intake beside the throttle body that has 1/4 inch lugs held on with a bolt - that is where to ground the sensor wire to give you o/d at any temperature. Hope this helps.
