i dont know where to wire it in on yours. its a 30v. mine is a 1.8t. I just replaced my original oil pressure sensor with the AEM one (which is a 4 wire) and grounded the original single wire to a ground to shut the dash warning light off. I can tell you that i wired power from the fuse block under the dash with a inline fuse.

 

Yes, the term is what it is a oil filter sandwich, Go to ebay or look online, Here is a link

I got one when I had an accord that I was going turbo, it helps you keep everything original and has 3 ports 1/8 NPT (National Pipe Thread) which in most cases your Gauge would come with a 1/8 NPT threaded sensor and 2 or 4 wires usually it would come with instruction on wiring bit all you do is connect the black to a good ground and the red to a hot side w/switch, I typically wire it to the ignition switch, that way it turns off and on when I turn the car on.

The way it installs is when you remove you oil filter it screws on where the oil filter would go and it has an external threaded stud for your oil filter, and that my friend is why it's called an Oil Filter Sandwich.

The Sandwich cost about 30 dollars free shipping, for the price it better be free shipping. Make Sure it's for year, make, and Model oh and Engine.
