Ive been searching old posts looking for where most people mount their oil pressure sensor. I have an electric sensor that came with an auto meter pressure gauge. It has a 3/8" NPT fitting. I have read that the OEM oil pressure sensor in our car is an "idiot light" type on/off switch. Since I am running an AEM EMS, could I just replace the OEM sensor with my new sensor? Or would this cause problems? I could short the sensor feed to always return "yes oil pressure" if needed. Let me know what you think, or if anyone has any better suggestions on where to mount them without buying an oil filter screw on mount. Thanks!

You can use the stock oil pressure sensor location, but you'll need an adatper with 1/8" male BSP threads and 3/8"female NPT threads. I ran a line from the stock pressure switch location into a 4 way tee which feeds my SC and oil pressure sensor.

Thanks for the info and pics John, thats a much better solution than mine. I have a supercharger also, and by using the 4wayT I would then also have a location for an oil temp sensor. Thanks, again.

you can just remove the stock one adn put the aftermarket sensor in its place, you will have no problems or check engine lights at all. The stock one is only there to turn the oil light in your dash on, but the if you have the gauge you dont need to worry about that. also the threshold is so low on the stock sending unit by the time it turns the light on you have more then likely already caused damage. You should also knwo there is another oil pressure unit that is used for the vtec system.

hope this helps!

Caution: do not screw your oil pressure sender into the oil pressure switch socket without putting in an 1/8" BSP adapter. The threads are close but several owners have stripped the threads on their block when doing this.

I highly suggest you screw in a small braided 4an line to the port, then put a tee at the other end and attach both the pressure switch and the pressure sender. This minimizes the chance of a fatigue failure due to engine vibrations.

Xviper has a great writeup on this if you do a search.
