I finally got my high idle to work on my 07.5 6.7. I don't think that grounding the pin on the ECM will work as I looked at it from what a guy told me that has a 5.9 and it was all differant. So I unsnapped the big white wiring harness under the dash, just behind the emerjancy brake. You can see a green wire with a pink stripe on it and a black heat shrink on the end. It isnt very long but long enough to strip the end and put on a connetor to go under the bolt (1/2 " socket) to ground it out. It took about 5 minutes and works great. I did already have my dealer update it and he told me it only works on autos and I told him to just do it and I will take care of the rest, he did and now it works with the cruise.

 

I don't mean to start a fight, but my truck and every 6.7L I've seen has the cord, has anyone tried to order the kit and see if the block heater kit comes with a cord, It might be different here in canada, but I sounds like to me someone is removing the cord and making some extra money.
It does not make sence to me the the block heater comes with the engine but you have to buy the cord, this is the first time I've EVER heard of this, especially in a diesel, except for some forign cars like honda for example, you can't get a block heater installed at the factory, dealer has to install it.
I dunno maybe the canadian trucks just get the block heater kit for free because my window sticker doesn't mention a cord or the heater.

 

i think your right. they are putting them on in climates such as yours. whether they're doing it for free or not i am not sure. they may just include it and up the msrp the whopping $10 bucks.

 

I asked that very question after I had to go back and buy my cord. I was told that they only put the cords on the trucks that are going to areas that they (Dodge) feel they are necessary to use. They said that New Mexico, Texas, Oklahoma and Louisiana, for example, are considered warm climate states and they do not deem them necessary in those states. I told them that it should not be up to Dodge to decide whether I want to plug in my truck or not. Why should the cord not be a part of the truck if the block heater is on the truck? They just repeated what they had already told me. I then asked well how come they don't tell anyone this? They said that they are listed on the window sticker if they are included. My response to that was, I have drived diesel trucks for 8 years and had never seen one that did not come with the cord or that you had to specifically ask for it to be included.

 

fords are the same way. my last '05 hade the cord and it was listed on the sticker for $35 if i remember right. but when i was shopping for it, i noticed some trucks had the cord included and some didn't. all came with the heater on the block, just like the dodge.

 

I bought my truck off of the lot in Colorado and it did not come with a block heater cord. The local Dodgr dealer said the cord was $65 through parts including install. I called my local Cummins dealer and got the same cord for $13 and took 5 minutes to install it. And, if you buy the block heater from Cummins it does not come with a cord, you have to buy that separate.

 

The cord hasn't been standard since 05 I think.

 

How do you enable high idle on a manual? I would love to have that feature.

 

i have written about it many time on several sites. here are instructions and a link....

you don't need any extra parts to enable the high idle on a manual trans!! i did mine and have posted how to do it before (on other forums). you need to have the dealer enable it, just like on the auto trans. the only other step is to ground the one wire. the wire is located on the firewall. driver side, far left bottom firewall. basically if you go staight back from the emergency brake handle to the firewall, you'll see a large wire harness, white in color. you can unhook that harness, and behind it there is a very short (4 inches maybe) dark green wire coming through the firewall. the wire has a heatshrink cap on the end. strip the end of the wire and ground it to one of the two bolts next to the harness. that's it! let me know if you need more info. you'll need your flashlight to see that little wire back there. that's it folks no money on any parts. that wire is for the optional clutch safety switch. it is really not needed, as the transmission has to be in neutral and the emergency brake set, in order for the high idle to activate. if you touch the brake pedal, release the emergency brake or put it in gear, the high idle will disengage.

Hi, I'm a newbie also. So what does the high idle do?

 

the high idle lets you control the idle speed between around 1000rpm to 1500 rpm. this helps prevent wet stacking (not burning all of the fuel, causing carbon deposits), and keeps the exhaust system (egr valve and cooler, dpf, etc) cleaner. if you idle your truck at all, you need to have the high idle feature operational!

 

Thanks for that answer. I've been told that it's not a good idea to idle the newer diesels. I guess it's for that reason. I envision buying a slightly used Dodge 3500 dually to pull a fairly heavy fifth wheel travel trailer. If I can't find a good deal on a used one, I'll probably buy a new one. I know nothing about diesels as you might suspect.

 

Its not good to prolong idle on any diesel new or old.Lots of older one had manual pull throttles.89 Dodges did.
