*PARTS LIST IN DESCRIPTION BELOW*
In this video, I show how I wired an inertia switch and fuel pump relay into an electric fuel pump circuit. I use a 4 pin relay, two inline fuses, a single pole single throw switch, and an external fuel pump for the demonstration. This type of circuit is great for if you are wiring a race car, a hotrod, or just learning the basics of car wiring. Hopefully you enjoy the video!
