If its a p-pump, the solenoid has 3 wires. ground, hold and pull coils. cant recall off the top of my head the color coding, but you want ONLY the hold coil to have constant keyed power. The pull coil can only be energized momentairily (usually energized with the starter) as it draws high current and produces alot of heat.

The big black one is ground. The little one in the middle is hold, and the one left over is pull. If you don't wire it through a relay, put an inline fuse in one of them just incase the starter contacts stick. You don't want to catch your truck on fire!

Reason: a to add more details
I got a wire harnes that is made for conversions for the fuel seloniod. It was like 30 bucks comes with instructions, and relay. It is complete just plug in and put the wires where it says. Just go to eBay and search fuel soleniods.
My shutoff solenoid went out on my 12v and instead of letting dodge rape me i went to tractor supply and got a throttle cable for a tiller or tractor and ran it thru firewall and attached to fuel shut off arm. Now it is a real mechanical shutoff and i could take keys with me and leave it running and locked all day long.
