It's interesting how the beat goes on about drawings. The subject has a life of its own. Electrical schematics & plumbing routing diagrams (IMO) hardly constitute specially designed & machined parts. They are certainly not trade secrets. Also, there is not an item in a coach that isn't off-the-shelf from another manufacturer.
Just think how handy it would be for so many to know if their bathroom sink empties into the black water tank or the grey water tank; or what water is filtered, etc.
Just think how nice it'd be to know what circuits are on each breaker; where the A/V equipment connections run, hey, where the splitter resides for the TVs.
My dealer claimed a need to "keep trying connections" till they get the right ones for the transmission overdrive operation & indication! These were connections into the transmission ECM (electronic control module)! One wrong move & GS would have been waranteeing a thousand dollar computer to the dealership. Fortunately, I went ahead & accepted my coach with an inoperable overdrive. Then pulled a couple strings within GS to get the exact expected connection, including wire colors & connector positions. No experimenting,,, On the 1st try I had OD & a yellow light. & while I was under the dash, I found out why & corrected the inoperative fog lights that puzzled the experts.
I previously worked for a company that manufactured paper processing equipment. True, we NEVER sent out detail drawings of machined parts, but we did provide assembly drawings. Our customers HAD to be able to dissasemble/assemble & adjust the equipment. Not be able to machine the spare parts, just use them. Similarly, the customer was provided with every wire connection, wire size, wire color, junction box, switch detail & the manufacturer part number needed to replace bad items.
Gosh, I get emotional over this subject... Ha Ha Ha. I assure everyone, it is a loosing battle with GS. They have their corporate policy & that's that. To vent my frustration, I have pretty much traced out & accounted for every wire & device in my coach by myself.
