Definitely EA81. The giveaway is the sideways mounted thermostat that faces to the rear of the vehicle.
The EA82 unit has the thermostat housing on the front of the intake manifold and it sits horizontally.
Hope this helps!

Bennie, PS "kits" of all the parts needed seem to sell easily for 550. I remember surprise at someone paying 100 and then going for reconditioning costs. I have thrown a few out before then Matey will just have to be content with what he gets or puts away again
Look to the exact schematic for your model and year. My guess would be that the wires go straight from the ECU to the sensor (i.e. no fuse between), so you're probably down to a wiring fault.
The solenoid grounds through the transmission case. Make sure the transmission ground strap is in place and has clean, tight connections with proper star washers to bite through paint.
