Help with where to install oil sensors on OFH

[The 92 Laser]

Ok so I bought a oil temp and oil pressure gauges(premium prosports) I have a 92 laser AWD with OFH off a 90 with an external oil cooler. I was wondering where to put the sensor at? I modified the pics(sorry they are a little ghetto Im not very tech savy) Any help would be great.
Thanks Ross

Both the gauges are electrical

4 is where you would put the oil pressure sending unit.

Here's what I did to install it:

Ok so i guess your using a mechanical oil pressure gauge? Mine is an electrical so i would do the same thing but with the T right?
Thanks oss

I would get a T BSP fitting for spot #4 and install them both there. That's the stock oil pressure gauge location.

You could also get the sandwich plate Prosport makes. Not sure it would clear the alternator and downpipe on a 1g with the 90 OFH though

Sorry to thread jack but what goes in spot 2? Mine has a plug in spot 1 and an open one in spot 2.

Bringing this back up because I need to get this done and didn't want to start a new thread. Using the picture from OP, I have an open thread in 1, a plug in spot 2, feed line to turbo from 3, and oil pressure unit on 4. What do I do with 1? Should I just plug it?
