Scan Gauge application?
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!
