It's now a $9 option on ordered trucks from Dodge.....

 

Go to your Cummins dealer and get the cord. Dodge rapes you. I got mine the other day at Cummins Great Lake here in WI and the cord cost a whole $10.66 but I had to pay $5.00 for them to ship it here. That took all of a day. Save your self time and money. The fleetgaurd # that is posted is right on. Also it is a very easy install, you just have to use zip ties instead of the push pins that come with the Dodge cord.
