Any info on the RoadRelay4 or other simular system for the 2003 Cummins HO Engine would be appreciated.

I have read a little bit about it but don't know a whole lot about it. Seems really intresting. Maybe someone who know can tell you haow they like it or what not. But here is a link to Cummins site. http://www.cummins.com/na/pages/en/p...lectronics.cfm

I called and asked about it, Cummins said that Dodge is not giving them the information they need to be able to make a Roadrelay 4 for the 3rd gen trucks. Could be wrong through, I called about a month ago looking for one for my truck, Cummins has a 800 number for the electronic stuff on thier website, that's what I called.

I wouldn't hold your breath. with the 03s, DC forced Cummins to produce an engine that they could not work on. seriously, DC is protecting their own service shops by preventing you and I from going to Cummins for service, something we can do now with our pre-04 trucks.

They would have to re-design the system to be compatible with the DC computer system.
