Fuel Pump Wiring

The wire I'm thinking of is thicker than the stock pump crap. IIRC it's something like 12-14ga if I am thinking of the right one.
Yes that's the wire I'm talking about. Do you know what size it is approx? I'm thinking of tapping into that wire at the fuel tank and run a wire to a relay near the pump module and use the stock pump wire as a trigger, just like you described. If the trailer wire is fused in the stock fuse box that would be sweet.
If your talking about the power wire that runs to the rear for trailer brakes, that would work, but your gonna have to find it in the fuse box and repin it for a relay.
I just hooked power to the battery under my truck and ran a 8ga wire back to the tank. Used the factory Fuel pump wire (grey) to trigger my relay. Im runnin two 255 pumps all the time ( i forgot about hooking the second one up at the track and havent unhooked it yet) fed from a 10ga and a 8 ga wire. with a 8ga ground

You should be able to tap into the Accessory power wire for the trailer harness. It's bigger than most of the wires, so should be able to handle a higher load. I want to say that it's fused with a 40 or 50 amp fuse. From the factory they aren't connected at the fuse box, you'll have to check and see if yours is or if it needs to be hooked to one of the accessory studs, and you'll probably have to add a fuse for it as well. I'd imagine that would handle the draw...the downside is that it's always hot, so you'd have to figure that part out.

but i believe that factory wire is a 14ga?
