Electric fuel wiring questions...

[Big Calo]

Getting ready to do an electric system for my cousin. I did a search and turned up for a power source there is a terminal on the back of the fuse box, behind a little lid, to tap in to. I'm not at my truck right now to actually put my eyes on this but will check it tomorrow.

What I have now for the wiring is 12ga wire, 30 amp inline fuse, and a 30 amp relay.


What I didn't find is where do you guys get your key on power for the relay?

Use th original fuel heater wire for your trigger key on tap.

You can use the side of the glow plug relay that ISN'T the brown/orange wire for the keyed power.

You can tap into stud on the fuse box where the battery connects too.
