Hi Idle Mod
Ok, must be stupid or something. Found all the wires needed mde the connection and it don't work. I tried the orange wire and found in another forum the purple/green str wire (BAC) ad neither worked. Are there fuses somewhere for these switches? I looked behind the eglove box but only found relays and a 5amp fuse but I understand the switches are 10 and 30 amp would assume the 10 & 30 amp fuses to be somewhere?

One more thing
In "JimRietz" wonderfully written discription he states the orange wire is used for the Idle mod. and then connected to the appropriate upfitter switch. In another forum it is stated that the BCP or purple/lt.grn striped wire should be used. Which is correct or the differences in either?

From the diesel stop website for the high idle for 05+
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

I have heard that the orange wire holds the rpms at 1200 rpms and locks the torque converter and was designed for use if the trans had a pto adapeter on it. The purple wire was designed for stationary running applications and is electrically based. It will not lock the torque converter and will raise the rpms to at least 1200 and it will go higher if there is a higher electrical demand. I have also heard that you need to have the ebrake pressed for the purple wire and not for the orange.
So, they both do raise the idle... I chose the purple wire because I though it would be handy for recovering from the glow plug usage and if I were trying to jump start someone.
edit - ^ he beat me to it...

Which wire?
"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)."

Thanks
i wasn't sure what the orange one was. I will change it to the purple, should have when I was there. Thanks

I was curious if anyone with the orange wire could comment if the trans warmed up faster with the torque converter locked up or not...

Good question.
If I had the 06 I would have leaned toward the BAC wire.
