You tap into the head right under the coil on the passenger side:

You can use the 1/8" tap to tap out the port and screw the connector right in, like I did, or if you're worried about taping the head, order a Autometer 1/8" BSPT adapter.

Here's an install article:

Mark, does the BSPT adapter have a 3an fitting and it just screws in without having to tap the hole?

The 1/8" BSPT adapter from Autometer has a male 1/8" BSPT thread on one end and a female 1/8" NPT thread on the other. The F-Max kit comes with a -3AN to 1/8" NPT Male thread on the end that's supposed to tap into the head.

In that picture the braided line actually goes to an Oil Pressure sender I installed on someone elses car. It has the 1/8" BSPT adapter screwed into the head. The 1/8" NPT to -3AN adapter fits into that and the -3 braided line fits onto that.

Yes, there is no need to tap a hole/ THe 1/8" BSPT adapter screws right in to the stock port.

Cool, I'm glad to know about this, better spending the 10$ then deal with tapping another engine. It worked fine, but you can never be 100% certain no metal bits get inside.
