WoooHooo! Easy Peasy.
Found the wiring diagram for the velvac mirrors here:
https://www.velvac.com/sites/default/files/resource-files/2020_wiring_diagram_-_ford_e-van_7475242_12.pdfThe Velvac mirror was trapping water inside between the mirror casting and the gasket. Thats what was corroding the outside, it creeped around the edge from the inside. Lucky for me the gasket protected the door...could been nasty. Still works fine... anyone need a pair of mirrors?
The connector on the new mirrors had 3 terminals, one appeared to be a common, with two wires on it. Pushed wires in... and it worked! (But horizontal was vertical..) Switched the two single wires, and it was fine.
So it ended up using the yellow, black and white wires from the original controller. Yellow was common, connect to the two wires from the mirror. Black on the coach went to yellow on the new mirror, and white from the coach to green on the mirror. Works perfect!
No heaters, so i put a pigtail on the + wire and left it protected. Might use it to switch ramp lights.
Put the new headlights in...
Damn. Looks new, and the pattern is SO SO SO much better than the old ones. Sharp cutoff line. Painted the grill areas that were gray to black, it looks like an Explorer? Expedition? Definitely changed the look, but looks factory. Will post pics, between finishing windshield, lights, and TV mount i didnt get online, much less post pics.
Also got the LED lights put in the headliner to light the front area. The original light didnt cut it.. now there is NO lack of light. Used these:

Mrs V is VERY happy with the new look on the coach. Mission underway and going well!
