Just finished doing my first mod to my 2005 F350 KR, and boy- was that easy- 10 minute job and hardly no effort required...it's what they call the New Stationary Elevated Idle Control for 2005 Model Year Light Trucks
. Basically, it's a mod that will allow you, upon certain circumstances, get a 1200rpm stationary idle for options such as PTO applications, or for any time where you will be idling for more than 5-10 minutes and need a higher idle. Not to get too in-depth here, but the 6.0's have a tendency to "wet-stack", which means on a persistent idle, the un-burned fuel in the cylinder has a tendency to pass the rings and into the oil resevoir, therefore "making oil". This simple mod will eliminate that condition if used. For practical purposes, if you are idling for an extended period of time, it will also allow better cooling circulation (both engine and A/C, if used). For this simple hookup, you will need a 2005 truck that has Outfitter Switches, but it can also be accomplished by fitting in a standard switch, but this will not detail what you need to use a standard switch- only the Outfitter Switches.
I 'borrowed' a post from TDS that even makes this alot easier...thanks to 6Robert2, who I believe actually borrowed it from another post.
<span class="ev_code_BLUE">You will need the following:
1ea - 2005 Ford Truck
2ea - red butt connectors (or solder & tape)
1ea - available UpFitter switch (although any 12v switched source will do)
1ea - access to this forum
1ea - crimping tool
1ea - long nose pliers
6" - stranded hook-up wire (14-16 ga)
11 mm - socket
1ea - ratchet for socket
1ea - ability to follow directions
1ea - garage large enough to enclose the truck (especially when raining)
1 to 6 - 12 oz refreshments
1 - Ford Tough tatoo
1ea - Electrical Engineering Degree
1pr - non-conductive footwear
Remove all rings, watches, & bracelets (a must when doing electronics)
Remove the drivers side access panel (below the steering wheel)
Using the 11mm socket & ratchet, remove the 4 bolts which hold the fuse panel. Gently, pull the fuse box through the opening and leave it hang.
Look for the UpFitter wire bundle as noted in this photo:
Choose which switch you want to use. I used Aux-4 as it is one of the 10 amp circuits and only a signal voltage is required. Here is a list of wires:
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]
Pull the black end off the chosen wire and strip off 1/4" of the insulation.
Crimp one end of one butt connector to this wire.
Prepare the 6" wire by stripping 1/4" of the insulation off both ends.
Crimp one end of the 6" wire to the open end of the butt connector used above.
Crimp another butt connector to the other end of the 6" wire.
Locate the top of the parking brake pedal (approximately 6" below the AUX wires).
Locate the SEIC/CASC wire bundle (about 12 wires with black ends)
Locate the solid ORANGE wire. There are many orange wires in this bundle, but most have a color tracer. You must use the SOLID orange wire.
Pull the black end off the SOLID ORANGE wire and strip off 1/4" of the insulation.
Insert the SOLID ORANGE wire into the open end of the butt connector attached to the 6" hookup wire.
This completes the electrical portion of this project. You need to replace the fuse box and access cover.
All the following are required to enable high idle:
Parking brake applied.
Foot off of service brake.
Vehicle in PARK (automatic trans.)
Foot off of clutch (manual trans.)
Foot off of accelerator pedal
Vehicle speed is 0 mph (stationary)
Brake lights functional
Engine at a stable base idle speed
Start your engine! Flip the UpFitter switch. The engine will idle up to 1200 rpm. If any of the required items changes state, the engine will go to its normal idle speed. If the item state is changed back to the required state, the idle will return to 1200 within 3 seconds.
Obviously, you are at your own risk in trying this out- I do have to stress that when he says 'make sure you ge tthe solid orange wire", that's a tad difficult to find it, but then my eyes just ain't the shape they were in 20 years ago...so there!!
