When making the underhood connections, make sure you use the oil sending unit wire connection from the Montero - not the one on the StarQuest harness.

The StarQuest connector is just beside the detonation sensor harness connection. Tape it off.

The one you want to use is on the part of the Monty harness that runs under the windshield washer tank. This section of wiring will still be there after you remove the entire carb harness. You will find it right near the washer tank. Mine was resting on the fender well looking lonely. <img src="/forums/images/graemlins/smile.gif" alt="" />

Plug it in to the sender - you got oil pressure. <img src="/forums/images/graemlins/kewl.gif" alt="" />

Thanks to Monty McV and FastEddy for clearing these muddy waters. <img src="/forums/images/graemlins/cheers.gif" alt="" />
