Yes, thats the one I have, thanks!

My goal was to get the original gauge to be operational again, as the previous owner had installed misfit aftermarket mechanical temp and oil pressure gauges below the dashboard. No original senders where in place. I asked my workshop to reconnect the original gauges, which failed big time...

Thanks for all help! (I have not tinkered with cars in 40 years, so the learning curve is steep...) Problem solved - We have pressure!

Thank you all! Just wanted to round up my own thread, got the correct sender and located the right wire. YES! - We have oil pressure!

Yes, but the current one is a very misfit mechanical Bosch hanging under the instrument panel, I want to get the original gauge working again with a new sender, thats me. :-)

I appreciate your help indeed...but sadly we are on opposite sides of the globe. :thankyou:

I think it has good chassis ground, showing approx 0,5 ohms between the outer(black) nut on the sensor and ground on the engine.

Thanks, now I learned something today as well! I just have the new water temp sender to play with right now, trying to check the sender with an ohm-meter just shows an open circuit, both hot and cold, might be faulty then?

Trying to get the original temp and oil pressure gauges to work, I found a new problem. The voltage in the gauge-wires are pulsating from 0 to 7 volts, this happens with the engine turned off as well. Is this normal? (If I short the gauge-wires to ground, the gauges goes to max, so they...

I really appreciate all your help, but living in an apartment with a garage below where NO workshop activities are allowed puts a lot of limitations to my possibilities.

Thanks! So it´s not possible to check the sending unit resistance just on the bench as it will show an open connection as it does, right? (Good to know about quality issues as well, that might show up after installation then...)

No light, just gauge. No compressed air available, hmmm. The workshop installed an incorrect oil pressure switch and connected it to the gauge that pegged.

Got a new oil pressure sender unit for the original gauge. Just wanted to test it before installation, but it´s an open circuit, is it faulty unit? (Tested my ohmmeter with a small lamp, and it showed 5 ohm OK.)

I really don´t know, but the harness looks very stock to me, I though that connector should go to some sort of sensor on the intake manifold, uncertain of the function, see below.

Great advise, I will test that, starting with the brown wire suggested above. The truck does not have an oil pressure warning light, but the wire harness might include that connector anyway, sort of generic harness for several truck models? (Just speculating...)
