You may have bad valve seasl for the using oil part or the heads are plugged up and not draing back down, easy enough totell by pulling valve coverif you see a bunch of crap all over it's gunked up. I'm sending two harness drawings which tells the color of the wires and where they go, not much else help with this. Or you could get a another harness off of same year truck with same engine. I am taking this that it's a trooper and not a trooper ! With a2.8l engine. Otherwise this will be wrong. Temp sender is third pic, actually all sensors
