Question About Air Schematic Legend

It's too hot to work outside, so I'm hiding out in the house doing a little light reading, specifically, I'm studying my Air Schematic.  I notice that many of the components are marked with a upper-case letter inside a circle.  For instance, the drain valves on the air tanks are all marked "L".  The one-way check valves on the tanks are marked "I".  I assume there must have once been a "legend" sheet to accompany the schematic.

Question:  Has anyone ever seen this legend, or more to the point, does anyone have a copy of the legend?  My hope is that it might specify the actual part number or provide a detailed description of the OEM part.  That would certainly make it easier to find replacements, when necessary.

Thank you for any input.

Foretravel is a huge tease. They give you PART of the wiring diagrams and drawings when you buy the RV.......I've had the same questions about some of the diagrams.

That legend on the schematic is all you are going to see. Only Foretravel Part numbers would be shown anyway.
Mike Grimes in Parts Dept I believe has the OEM part numbers (The Holy Grail) you seek.  :headwall:

Thanks, Barry.  That is, sadly, the answer I expected.

I'd settle for at least a complete set of wiring diagrams that show dash wiring, component labels, etc. It's a shame they don't give them to the owner when they buy a half million dollar piece of equipment...or at least give the option to purchase for a few hundred bucks. I'm sure Prevost and bluebird have complete service and parts manuals available for purchase (or include them).

Ours came with an almost complete set of schematics, wire numbering list, etc.  Maybe yours got lost somehow before you got the coach?

Yes, it is possible.  Not hard to understand, since we are owners #5.  I feel we were lucky to get as much factory paperwork as we did.

It's not complete. I have all the pages, but when you really start needing to trace wires, like which wire from the light relay goes to the dash, etc....the info is just not there.
