Ken, i'll take a stab at this one. going by whats on my car.
the green wire coming off the ac compressor goes to the thermal fuse connector. 3 wires as u say
the green off that goes off that (middle wire) goes to the evap thermal switch, located by blower motor on evap case. I usually access thru side grill. this will also have a tan wire to it.
The black wire goes to the back of the compressor to the super heat switch.
I'll try and get some photos from my wire diagram and email to ya.
Ken
