Sadly no, thanks for the link. Before I got the RV I was reading those from cover to cover. I was very excited.
I was at the RV today, taking more of the Bus Wrap off, this time on the front of the slide which was in. I did get a lot of it off, but I also accidentally triggered the turn signal trying to fit between the driver's seat and the wall. When I was packing up I was near the battery compartment and heard the ticking of the relay that controls the turn signal. It was that plastic covered item with all the protected wires going to it. The one above the filter in the last pic above.
Very excited to have that one sussed too.
