Saw a question about enabling the high idle feature within the SMARTY software. Asked the folks at MADS and got this back:

I confirm that the high idle feature is automatically enabled in all the CaTCHER levels of Smarty S67.
In automatic trucks the high idle can be controlled by the cruise control.
In the manual trucks, the Dodge kit for high idle has to be installed in order to use it.

Now my question is what is the kit he is talking about.

Thanks,
Hal

You have to install a clutch switch. The clutch switch tells the computer whether the clutch is engaged or disengaged. It's basically a safety. Unless somebody jumps in with a link you'll have to search for the info on the part numbers and install. There's allot of confusing info on this so don't be in a hurry to buy parts until you sort out the particulars.

What are the benefits of having a high idle?

In the summer it will help your alternator keep up with the demand from idling with the air conditioning on and help the air work a tad better. In the winter it will help keep things warmed up a little also.

I have read (maybe on this forum) about grounding a wire that is in main harness near the clutch pedal that allows the hi idle to work. This wire must be the one that connects to clutch switch. The dealer install of the switch plus parts was about $300 when I asked about it at dealership.

I use it in the winter all the time. I go out and start the truck, turn on high idle, run back in house and then leave in about 5 min.

There are many posts on this in the 5.9 section. You do not have to have use the clutch switch (which by the way is expensive). On my 04.5 I used Cummins part number 3164263, costs $12.50, and its simply a wire with a male metal pin at the end which you plug into the #22 slot/port of your ECM. Put a ring terminal on the other end of the wire and ground it (use the bolt right next to the ECM) The ECM is located on the drivers side of the engine. Total time is about 30mins including coffee/beer. Load up your Smarty or go to the dealer and have him enable the PTO high idle feature. If someone needs more PM me and I will pass along info on a good "how to post" that is on another cummins diesel forum...........

The process to circumvent the use of the MOPAR clutch switch is different on the 6.7L trucks than it is on the 5.9L 3rd gens. All you need to do on the 6.7L/G56 trucks is ground one particular wire under the dash within the area of the 100-pin connector. Here is a picture of where it was on mine:

Thats why you're the man! . Good accurate information.

I have an 07 6.7 and I have looked and looked for this wire. Can you PLEASE show me this wires exact location? Lol I'm really wanting to get it done and I've spent orobably close to an hour standing on my head pretty much looking for this thing. Is it hidden in with all those other wires or what? Does it come out of the fire wall with the rest of them? Thanks a ton in advance!!!

You're not the only one Jweems21!! I can't find it either. I've had my truck a little over 2 years now, and I periodically get a wild hair and try to enble my high idle. Like you said, after about an hour of squeezing my 6ft 3in 230lb frame under the dash, I still can't find it. My truck is an 08, but I wouldn't think there would be much difference. Hopefully someone will be able to help.

Jweems21

Everybody I ask says "it's behind the harness" and that's as far as their help gets so hopefully I can get some real answers here!! Lol Im really wanting it!

I believe it comes out of the firewall but I can't be certain. It was about 6 years ago when I grounded it. IIRC, I removed the two bolts attaching the bracket holding the 100-pin connector to the firewall and the little green wire was tucked away behind that bracket.

Your best bet is to start taking things apart down there (within your own skill/comfort level) until you find it.

Jweems21

It's there!!! Lol I finally found it and grounded it. I took out the two bolts and removed the bracket, then took my iPhone and turned it on video and turned my flash on and looked around down there with it (using video makes everything easier to see where as you're looking at your screen.) it's in with all those wires but after it comes out of that last piece of tape holding them all together, it doesn't come down toward the harness, it's turned back out of the way. You might even be able to just take your hand and feel around and find it lol but I promise it's there haha i didn't think but I wish I would've took some picture. Also be careful when you go to put the end on because the wire is pretty short. I'll probably go back and add on one day and re do mine because it's kind of pulling on it. I hope this helps!

Nice!!! I'll take a look when I get home in a couple weeks. After you grounded it, how did you enable it? Just turn on the cruise?
