I need your help, if you have installed an oil pressure gauge please tell me where you installed the Oil Pressure Sending Unit. I know where to hook up everything besides this. Please HELP!!!!

You'll need an 1/8 BSPT (male) to 1/8NPT (female) adaptor that can be had for about $6 from www.mcmaster.com get the stainless steel one, its the best. The stock oil pressure sending unit is on the rear passenger side of the engine, on the same bracket that the oil filter hooks to. You'll need to get an oil pressure sending unit socket from an autoparts store and screw the adaptor in there with teflon tape then put your sending unit in there or the line or whatever you have(mechanical or electrical). Hope this helps,

I got one of those, and its great, I can have the idiot light (stock light on instrument cluster), my autometer gauge and oil feed for the turbo. Very nice piece!

I have an Splitfire electric Oil pressure gauge, it has 2 adapters. You should be able to match it with no problem. It took me an hour to install and wire.

Be careful if the adapter is brass. Brass adapters are known to break on a regular basis.

ok now im confused if the threads are 1/8 bspt where the idiot light plugs in then why on the adaptor would they only have 1/8 npt female holes wouldnt you need at least 1 1/8 bspt hole for the stock sending unit

If you are talking about the nissport adapter then it has 3 1/8 NPT and one 1/8th BSPT hole. I attached it to my car today and everything works great. In the process of doing a oil temp gauge and also the water temp gauge. The oil temp is much harder since I decided to tap the gauge into the oil pan.

yes but the original oil sencerhas 1/8 bspt threads how can it be screwed it to a 1/8 npt hole and not cause proplems

The adator that was mentioned previously in this post has 3 1/8" NPT female ports and 1 1/8"BSPT female port on the end for the stock dummy light to hook to, it also has one 1/8" BSPT Male where it goes into the oil filter bracket.

I just finished my three gauge install and will post pictures for everyone with a how to tommorow.

is the stock oil pressure switch, under the car on the passenger side? does it have one yellow wire coming out of it?
I was down under that side of my car when i replaced the knock sensor and i was wondering what that was?

Yeh, its right there near the knock sensor, it has one wire and has a rubber boot covering it. Not sure what color the wire is though.
