where are these wiring diagrams ?

When the Winnebago wiring diagram says: "see manufacturers diagram for additional information" where does one go for that ????

That is often where the Winnebago portion ties into the chassis which is built by others. In your case, it is likely to be info from Chevy that is needed and I find that is much harder to get for the speciifc items we often need.

I will contact Workhorse and ask for assistance there. I am trying to repair an intermittent power loss to my dash 12v outlet. I plug my Garmin into that socket. There is a small 20amp atc fuse w/orange 18ga wire for the cigar lighter going somewhere (?) and eventually one of those yellow (but in this case 10ga !) wires attached to the 12v outlet. Trying to track that part of the harness. I will go looking for a relay that may change the wire gauge. Also going to check other devices that may be on that same 'LS' wire circuit. Also curious: What devices are controlled by that large rocker switch "Engine' vs 'House' ??

Careful!! When you speak of 18 gauge wire and 20 amp fuse, my first thought is it was added by a previous owner without too much thought!
Of course that could be totally wrong but when I think of dash 12Volt outlets, I tend to think of them as fused pretty light and not 20 amp!

My thought is that it may go just about anywhere that a previous owner might have found??? Or does it look like original?

On the switch, I suspect that is the switch for changing radio power from coach to start battery and it does likely go to a relay. I tried to tie into that as a handy spot for both battery supplies as a quick,easy point to add a small volt meter on the dash to watch as I started the engine. But the dash switch also made the polarity change and I blew up the two dollar E-bay meter before I figured it out!
On a 2015 Vista, the relay was way back inside on the firewall where I could hear it but never saw it before trading the RV!
Sometimes there are mysteries that I never solve? The RV after 2010 do not have the complete wiriing schematics that pre 2010 do. Without wiring charts, those mysteries are much harder!

Richard, all this wiring looks very much original. And that 10ga wire to the cigar lighter is more like 8 or even 6 ga ! (I found some wire marked 10ga and this yellow wire is 1-1/2 times that in diameter.)

I1v3fr33ord1: Thank You for the link. I have studied those diagrams (for Hours) and they are very helpful. I need to find a 'component locator' and there are items I have not found yet. It is certainly another piece to the puzzle.

My greatest difficulty is discovering the interface between the multi-colored wires of the Workhorse wiring to the Yellow+ and White- of the Winnebago wiring. Again, the smallish orange wire under the small atc 20amp fuse in the I/P extension (C254) to the heavy ga yellow that directly powers both front 12v outlets.

That component locator is your 3D interactive parts list. You can isolate individual parts by location down to the smallest items.
