Ive been researching for a few hours on this topic and I just cannot get a definitive answer.....
I am wanting to remove my factory oil pressure switch, and install an actual pressure sensor

My questions....
1, Is it possible to wire directly into the gauge?
2. Do i HAVE to have the OEM for the PCM?
3. What modifications will I have to do? Remove any resistors?
4. What are the specs on the threads of the OEM unit?
5. Does anyone have a part number for a good sender and/or have done this?

Im trying to get the most straight forward answer to see what plan of attack I want to go with, and to help others googling this with no straight answer.

Not going to work. PCM is looking for a signal from the Oil pressure sending unit.

So the aftermarket wont give the PCM a signal?
Curious as to how the switch will differ from the sender unit, I understand the switch is open until a certain pressure, then the switch closes, so then how exactly does the real gauge work so that it doesnt give a signal?

Carcrazygts2

It responds from the pcm. The gauge is driven by the pcm.

Any way to get it reprogrammed for a mechanical sender? I know the easy route is the external gauge, I'm just driven by curiosity.

No. You wont be able to change the way the gauge responds.

Where is the best location for an aftermarket sender?

Damn shame. I've really wanted to try and get an acutal working oil pressure gauge. not some dummy light.

You can add a mechanical gauge if that's what you're wanting to do.

I will be.

If you're just wanting to know what you're oil pressure is.
