PN for the Cummins Jake Brake switch

[Mark.Smith]

Anyone have the part number for the plunger switch on the stick that operates the Jake Brake on the 2005 models? I have looked everywhere and can't find it. Our local Cummins dealer says he's never seen one.

I "Think" it's discontinued...but I'll check...

The part number supercedes to a dash mount rocker switch........not good...

is the most economical way in my opinion. You will have to craft up some way to mount it if what you already have can't be modified...

Thanks for the info! So far my switch is working but at some point it's going to go T/U.
