this thread, which is somewhat helpful.
I will be looking for the same thing (next week) in our 2003 UF. I want to get the VMSpc bundle, and some tire monitors. I looked the other night briefly, but didn't see it. Does the UF's dash hinge up, by chance? SilverLeaf told me they thought 2003 was right about the time Cummins switched from the 6-pin to the 9-pin plug, so I am definitely going to have to scope it out before buying.
By the way...SilverLeaf Electronics also sells Pressure Pro, which does not offer the capability to replace the batteries in the tire sensors themselves. But that system interfaces with the VMSpc, which would be quite valuable, near as I can tell.
Can anyone help with any additional information on these things? We bought the rig last Fall, just in time to put it up for the Winter. And we just got it out of storage last week--we're using it for the first time next week. Lots to read!
Thanks in advance!
