Temp sensor on pside oil line is tranny temp sensor for overheat light on dash, set to come on at 122*F per FSM.

The o/d relay grounds thru the temp sensor on intake/water neck, smallest sensor, single wire. Absence of a/c compressor will not affect ground path. Ground the sensor wire and see if you have o/d. Check sensor for corrosion preventing grounding. Or check with ohmeter for continuity from connector to ground...
