2006 F-250 6.0 Diesel (equipped with upfitter switches).

I want to hook up a 12 volt fuel shutoff solenoid for an auxiliary tank.
Is it as simple as connecting a wire from one of the four UPFITTER wires under the hood to the solenoid and providing a ground wire?????.......or am I missing some of the details.

Any Help Would Be Great since I don't have a good understand of wiring; I just usually look for the sparks!

 

There are four wires under the driver side dash that are for the up fitter switches. They are in a wire loom and can't remember off the top of my head what colors but if you look under there you will see them above the e brake. The wires that are in the engine bay on the fire wall are just that, dead wires so you don't have to run wires through there. If you use them you have to hook them up to the wires I mentioned before.

 

The AUX wires are behind the fuse panel above the pedals, you have to remove the four 11mm bolts that hold it in and pop it out, then there will be four wires labeled AUX1-AUX4. The customer access wires (dead end pass-through wires) are in a bundle over the e-brake pedal and come out in the engine bay above the master cylinder.

If you want to run wires other than the pass through wires, there are rubber grommets in the rear wall of the cab behind the seat, behind and above the brake pedal on the firewall, and under the carpet under the driver's feet.

Aux-1 Circuit No 1936 wire color: Orange/Lt. Green [30amp]
Aux-2 Circuit No 1933 wire color: Orange [30amp]
Aux-3 Circuit No 1934 wire color: Orange/Yellow [10amp]
Aux-4 Circuit No 1935 wire color: Orange/Lt. Blue [10amp]

What kind of shut off solenoid is it? The AUX wire will provide 12V, but only when the key is in the ignition and turned to run (KOEO and KOER IIRC). It goes dead when the truck is turned off and key removed. If this is like the FSS on a Dodge you'll need a ground, plus one wire to pull (open) and one wire to hold the solenoid open once it's pulled. Then the solenoid will close itself once you kill hold power.

 

Thanks for the feedback
It is a “Dan-Mark” 12 Volt Multi Fuel Shut Off Valve - normally closed and opens when 12 volt is applied. They have several models that get a little pricy but I am looking at the Item# 79-AFC11112 sale priced @ $33.95

Engineered for use in automotive, industrial, marine, motorcycle, temperature and dispensing control applications. . Minimum draw - .75 amp, 12 VDC when fully energized.

So if I understand this correctly:
• To control ON/OFF for the fuel shutoff valve with the upfitter switch.
• Do not use the wires under the hood.
• Do use the wires under the dash behind the fuse panel above the pedals.
From the chosen wire, run an extender wire through a rubber grommets to the Fuel Shut Off Valve and attach a ground wire to the sheet metal.

 

If the solenoid is in the bed, yes run a wire out the grommet on the back of the cab, because hooking up to a pass-through wire that ends up in the engine bay won't really help you out.

I'd put an in-line fuse holder between the Aux switch and the solenoid just for a second layer of protection, with a 1A or 1.5A fuse in it.

 

Thank You Texastech,
You certainly saved me a lot of head-scratching and second guessing.

Have a great day, you made mine much better.
