Exhaust brake feature
Hello All,
I am loving my 2012. I had on my 07 a Pac Brake and always left it on but in severe winter driving. I wish I could do the same with the factory exhaust brake.
Is there any way I can get the Tow Haul and Exhaust brake turn on by default?
Brother would like to do it in his 2013 too.

I'm not sure why you would want the exhaust brake on when on a slippery surface as it will spin the truck quite easily. I do remember a thread on here about wiring the 2011 truck so that it would always turn on though.

I had it on almost all the time. I turned it off in severe weather.
I will look for the 2011 post.

I don't think the 2010+ trucks can be wired like the earlier 6.7's due to the accessory switch arrangement. I've been told that the truck and be reflashed so the exhaust brake switch remembers the position it was in upon restart. Shut the truck off with the switch on and it will be on upon restart.

Old thread I know but what is the benefit of leaving the exhaust brake and/or tow haul mode on all the time??? I LOVE mine but only use it while towing....us there an added advantage of using it all the time???

None really. Tow/Haul acts like a sporty mode with higher shift points and better throttle response since the engine is likely running at a bit higher RPM when you step on it. When on the highway in 6th gear and not in Tow/Haul, the tranny drops back to 5th easily and takes a while to respond to pedal input.

Yes... using the exhaust brake on slippery roads is basically has the same effect as an aggressive downshift with a manual transmission. It will send you on a ride you most likely don't want to take.
