Cheap fix for the dreaded bad fuel shut off relay issue.

I got pissed off and realized i could simply wire up a cheap ford mustang starter relay in place of the $100 plus one that plugs in. the ford starter relay is 12 bucks at kragen's.
just supply the 12 hot from the original harness to one of the large posts, the power out to the plunger solenoid to the other and the hot when crank goes to the small terminal on the relay. it does the same thing that the factory one does but can handle a hell of a lot more current. the last wire on the factory plug is just a ground. since the ford relay gets ground through the mounting tabs it is not needed.

If I recall, those Ford relays last forever, too. The Cummins relay is hard to find when you need one, I'm definately going to try this if my relay goes again.

manual shutoff

i put a manual on mine once it fell apart, was and easy and works great. one less electronic gadget to mess up.
