Can you do the same thing by tying (GN/OG to YE/GN) and put a 20k ohm resistor between (GN and BU/WH)?
I'm not sure so just asking? It would be a lot cheaper and pretty easy?

There are how to’s on YouTube where guys do this and it’s cheap. Under $10. The BD kit is nice, plug and play, and adjustable

So, I have the BD kit. I went this route so that I can adjust the rpm and two, I can switch it off so it does not automatically go into high idle every time I stop and set the parking brake. As I am new to the 6.7, what RPM are you folks using for a situation like sitting on the side of the road in winter waiting for the road to open? I have spent countless hours sitting off the I-80 between Rock Springs and Laramie over the years and while I never had an issue with the 7.3 and I could just let it idle all night, I am adding the BD to bump the RPM up a bit and I was thinking of running it in the 1,100-1,200 RPM range. Anyone out there know the best high idle RPM for the 6.7 to keep everything working properly?

I don’t have the high idle kit but I did do the resistor mod which gives me 1200rpm. In -40C, 1200 rpm not only keeps the truck at normal operating temps, it does a great job of warming the truck up. I don’t see a need for anything higher. I idle at least 5hrs per day at work in some of the most extreme cold temperatures that most wouldn’t see.

Mounted mine on the passenger side. Set it in and forget it. I heard 1250 rpm is the sweet spot

For me 1250 is too high. I have mine at about 1050 which works great for my climate.

Thanks for the replies,
I was thinking 11-1200 as a ballpark. I see one of the systems run at 1400 but that is too high for what I need. I should only need it when the interstate is closed but I have read so many horror stories about how sensitive these new systems are that it makes it difficult to weed through all the opinions. I told my wife that I will just take the 7.3 until I figure out this 6.7.

Mattymax - I plan on leaving mine switched off as I don’t want it to activate every time I pull into the driveway and set my parking brake. I will probably mount it on the drivers side or maybe in one of the console compartments so it’s out of the way.
