F.Y.I. since I could not find any info on this on this forum I decided to post this for others,as an alternative to the dash switch for use in autos,here is a switch bracket available from Pac Brake for auto trans. equiped trucks Part # C18081..$30.00 Can.. Add your own small toggle switch.Simmilar to the one for mannual trans.Very handy to use.

 

Has anyone tried using the exhaust brake switch and bezel from the 6.7 trucks yet? Or is not a simple open closed contact type switch?

Its just single pole switch,you need to ground the input to the ECM to make it work.I've driven the 6.7l and tried the brake switch on it too,I like mine better,just flick it on/off with your thumb,its easy to find witout looking.The bracket could be just a bit smaller ,but its ok.

 

Why would anyone shut the brake off. Mine is always on. I actually could live quite happy if there wasn't even a switch - just wired in the always on condition.

So seriously, why do you shut yours off?

 

Some people shut them off when driving in the winter. It's a scary situation on a snowy road when the back end comes past the front... I'm sure theres other instances too I'm not even thinking of.

Anyone have a part number for this bezel he talks about? I want to get one to mount other switches on - my stock one is a storage pocket....

 

You don't always WANT it on. Going down a hill with the brake on sometimes I'm going too slow, I turn the brake off and use the brake when I need it, plus, as already mentioned going down snowy or icey roads with the ex brake on the rear end tends to lock up.

 

I leave mine on most of the time.

I will shut it down when in the snow, without chains.

I also will always shut it off when climbing long, steep grades with lots of sharp corners, during the summer. Compressor cycles on/off with each corner. Compressor has a duty cycle of 25% so it will heat soak, with all the continuous on/off cycles and then not work until it cools off (30 - 60 minutes later). The heat soaking is more problematic due to my compressor mounting location at the front of the engine.

If I were to do it again, I'd mount it in the alternate location in the fender well that PacBracke now describe.

 

Can you elaborate on the location in the fender well? I will be installing mine in the next couple of weeks and would like to check out this option.

 

For the most part my PacBrake is not shut off either, but I do shut it off when snow or ice conditions exist.

I am moving my brake off the engine mount, just gets too hot there, and it does heat soak a lot. I was looking at several places that could be good aux mounting points, will have to go to Pac's site and see if they have any technical information on alt mounting places.

PacBrake site has a document in their literature section:

New Compressor Mounting on 2003 and newer Dodge Trucks

which describes how to mount it on the passenger side fender brace.
