I first wired mine using the oil pressure switch. I had troubles I thought were something else. I don't drive it a lot so it took me a while to realise i did not have those troubles in cool weather. Anyway I changed the system over to a wiring kit with relay and it doesn't give me those problems, which I now realise was the fuel pump cutting out because of how hot oil affected the pressure switch, any longer. And this is an inertia switch which I have not yet gotten or installed to shut it off in an accident. That channel has a vid demonstrating how they work and how to add them. https://www.ebay.com/itm/166629703151
Here is how I mounted mine in front of the tank under the skirt driver side. I used 1/8 sheet metal saved the OE mounts and added them some welding involved. Make sure your gas is low when you do it.I plugged the return line where the hard line ends up in the engine bay. I used a gas rated hose that I plugged with a bolt after a silicon cap melted.
