I have a 04 6.0L psd and would like to put a high idle on it can I do it throw ecm on the truck??

 

This works well I did it to my 04 will raise your idle to 1200 rpm with just a toggle switch.

thanks for the info...

 

I wired in a switch like mod sed... getting 12 volts at white w/blue wire but still no fast idel... any help...

 

What switch did you use i use a toggle single pole on off. I had no problems. Make sure when you start the truck have your foot off the brake and turn the switch on if you have your foot on the brake it wont work.

 

I used a single pole switch... and even tried a jumper wire... checked with meter and getting 14 volts at ecm...

 

BigDog13,

Check out this link:

It talks about some trucks needing the emergency brake set before the high idle will work.

 

BigDog13,
If its any help, your switch should have 3 terminals, wire 294 goes to source(positive, +), wire 322 goes to ACC ( Accessory ) and the 3rd terminal is grounded. I wired mine in this manner and it works fine. The switch also has an LED that is lit when on and a protective cover. This is on an '04

 

I am planning on doing this mod saturday. I took delivery this morning on my 06. I am looking at wiring it upp to one of the upfitter switches, I shouldn't have any trouble should i?

 

This is the easy step-by-step instructions to set up your '05 or '06 Super Duty to have a high idle option. This is for diesel trucks with the factory auxiliary upfitter switches. This procedure replaces the need in the older trucks to buy an AIC (Auxiliary Idle Control) module from Ford.

Tools needed:

Ratchet with 10mm socket
Wire stripper
Crimper

Parts:

One butt connector for 18ga wire

How to do it:

• Pull the full panel cover off. It's the big panel just below the steering wheel. The top just pulls out from the dash and then swings down to let the bottom catches come free.
• Remove the 4 bolts (10mm heads) that hold the fuse panel in place. Pull it out and let it hang down.
• Find the upfitter switch you want to use (see picture above for location).
• Find the SEIC or BCP wire you want to use (same picture above).
• Strip the end of each wire 1/4" and crimp the butt connect on them to connect them together.
• Put the fuse panel back in place and reinstall the bolts.
• Snap the fuse cover back in place.
• Drink beer. (Very Important Step!)

SEIC or BCP Wire?

You can hook the switch to either of these wires to achieve high idle. However, they each have slightly different behaviors. If you're doing this mod to help keep the AC cold or the heater hot, or keep the revs up when jumpstarting somebody, then you probably want to use the BCP (Battery Charge Protect) wire. If you're doing this mod to use the PTO (Power Take-Off on your transmission), then you probably want to use the SEIC (Stationary Elevated Idle Control) wire.

If you want to hook up to the BCP wire, find the purple wire with the light green stripe in the bundle just near the top of the emergency brake pedal. Note: don't be fooled into using the light green wire with the purple stripe. That's the output wire for a BCP indicator lamp.

If you want to hook up to the PTO wire, find the solid orange wire in that same bundle (near the e-brake).

Differences in behavior:

BCP

• will automatically vary RPMs from 1200 up to 2400 to maintain battery charge
• does not lock the torque converter
• has an additional wire that is an output that can be used to turn on an indicator lamp to show that BCP is active. i.e. if you want to install an LED in your dash to tell you BCP is on. Since the upfitter switch has a light on the end of this, I don't see much point in this (if you're using a factory upfitter switch).

SEIC

• does not automatically vary the RPMs. Sets idle at 1200 (unless you take advantage of the additional control wire).
• has an additional control wire that you can hook to a resistor to vary the RPMs. You could install a variable potentiometer (i.e. a **** on your dash) to let you dial in whatever RPM you want, when SEIC is active - from 1200 to 2400 (I think that's the max).
• locks the torque converter

Which Upfitter Wire to Use:

There is a bundle of 4 wires. They are just behind the top of the fuse panel. They're all orange, with different colored stripes. They are:

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]

The high idle circuit needs minimal current, so you may as well use Aux-3 or Aux-4 and save the high current switches for something that needs it.

Final Notes:

By far, the hardest part of this (for me, anyway), is actually stripping the wires and crimping on the butt connector. There just ain't that much room on there to fit hands and tools. It would probably be a lot easier if you used a short piece of additional wire and two butt connectors, as the two stock wires don't have a lot of extra length between them to reach each other. Nevertheless, I managed to do it with just the stock wires and one butt connector, so I'm sure you can too.

Once you have this done, to actually try it out, you have to do this:

• start the engine.
• set the emergency brake.
• have the transmission in Park.
• do not have your foot on the foot brake.
• flip the upfitter switch to the up (On) position.

Once all the conditions are met, the idle will go right up to about 1200. If you step on the foot brake, release the e-brake, or put the truck in gear, BCP (or SEIC) will disengage and the RPMs will drop back down to 600ish. If you undo/redo the correct conditions (i.e. take your foot back off the brake, etc.) the RPMs will go back up within a few seconds.

 

I do have some reference photos, so send me your email address if you'd like them.

 

Question: What's the advantage/disadvantage to locking the torque converter? I notice it doesn't lock the TC in BCP mode, but does in SEIC. Why? Which configuration is preferable?

 

tvsjr:

You want to lock the torque converter when using the PTO provision if you are running a PTO driven pump, generator, aircompressor, etc. The PTO provision is standard on the 2005 and later M6OD 6-speed manual tranny. The PTO provision is an option (option code 62R) on the TorqShift 5-speed automatic tranny. If you don't use anything driven off the PTO provision, you would use the BCP wiring instead.

 

You lock the torque converter to run the PTO provision. The reason for this is that the PTO gear is splined directly to the transmission torque converter turbine shaft for the TorqShift auto tranny with the PTO option.

The PTO provision is standard on 2005 and newer M6OD 6-speed manual trannys. It is an option (option code 62R) on the TorqShift 5-speed auto trannys.

So, if you're not driving anything (hydraulic pumps, generators, etc) with the PTO provision, use the BCP wiring instead.

 

If you want to hook up to the BCP wire, find the purple wire with the light green stripe in the bundle just near the top of the emergency brake pedal. Note: don't be fooled into using the light green wire with the purple stripe. That's the output wire for a BCP indicator lamp.


I have the done the Stationary Elevated Idle Control mod, and it works great. Does the 04 F250 6.0L have the BCP option?? I have looked but can not find the purple wire with a green trecer in the same bundle of wires with the SEIC.
Thanks for the info.
