My wife and I recently purchased our first RV and we are very excited about it! It is a 97 Discovery 36RS with a slide out (36T?), Cummins 5.9 24valve, Allison 3060 DP. I was hoping to run a scan gauge to monitor real time conditions but so far after a lot of searching I have only found what looks to be an OBD-1 connector (rectangular plastic plug with 12 small square ports and only 4 prongs) in front of the firewall near the ECM. Am I missing something? Or is that the only diagnostic connection for this specific coach? If so, can is there a scan gauge that will work on OBD-1? Thanks in advance!

Are you sure you don't have a CAN bus. My freightliner used a scanguage D for the RV. Do a search on it. My rig is a 1999

Thanks for the info, Ranger Smith! I went to the Scan gauge site and immediately my question was answered! I found the CAN bus connection early in my search but did not realize that was what I was looking for! I have the 6-pin plug under the dash and in the engine compartment. Your help is very much appreciated!!!
