Should be 2 harness connections tucked/taped up in the dash, to the right of the heater controls.

If you have the 1 wire OP sensor...you will need to replace that with the 2 wire and locate that second wire in the under hood harness.

Oh....and you also need the harness(s) from the gauges

 

Maybe............ :D

The red low oil pressure light in the dash is Yellow/Green stripe and goes to the vertical terminal of the T connector on the sender. The wire for the gauge is Yellow/Blue and goes to the horizontal terminal on the sender

Did you find the connectors tapped up by the heater? Those plug into the gauges. Out in the engine bay should be the other end of the Yellow/Green wire probably tapped up between the alternator and the starter. If not there, run your own wire back to the gauge.

Yes...you need the 2 wire sensor to make the OP gauge work

Follow the wire(yellow/green stripe) back into the harness that goes to the idiot light senser that you have/had on your block, somewhere in there will be the stub because someone cut it off, or you will find it taped backwards, following itself back into the harness to keep it out of the way, I just can't imagine why they would make a harness without that wire. If you cannot find it after looking for it as I discribed, just wire it yourself, but you will still need a console harness for the gauges just for the plugs to wire it yourself.

Most likely taped up in the main harness....the only 2WD 720s that came with those gauges were the STs....I believe.

Are them two wires connected to anything? I do not know the napZ engine harness very well, all my 720 harnesses are diesel except for one 1980 harness i have in my 66 datsun 520, I went outside and got a couple photos of what you are looking for, my plug is wired in with the alternator, starter, and tranny wires, it has a big rubber protecter and a "T" plug.
