I had a 2003 Holiday Rambler with Cummins ISC (315HP) engine until recently when we got a 2009 Tiffin with a Cummins ISC engine (360 HP). I expected my VMSpc USB JIB to fit our newer engine but the plug is different! What are my options?

Yes, you will need to Buy the 9-pin Harness from us, and open the JS-501 JIB and remove the 120Ohm Resistor Jumper..

Well I got the cable and today was going to get it all connected. However, in the JS-501 JIB I found what appeared to be 3 jumpers. One in upper left, one about in the middle and one in the lower right area! No idea which one is the right one to disconnect! Anybody out there know?
