Yet none seem to function on my vehicle other than a light that lights when fuel gets low. There is at the base of the dash, though, a 'maintenance' plug in which provides all this information to a properly configured reader. I have friends with Winnies who have bought an after market reader that uses the same source on their RVs to provide performance data; maybe there is such a gadget for the Sunseeker vintage base chassis
I believe the reader you are referencing is called "Scan Gauge" about $150. It will work on any vehicle (including the Sunseeker) with an OBD port under the dash.
