Hopefully soon. I have to get over some knee problems before I can get up there. Is there something particular you are looking for under the wingman? When I did have it off once before to clean it, there is a "W" shaped opening in the bottom. You can see what looks like a greenish circuit board inside. I don't recall seeing any numbers.
I. Sent, you answered. You needed me to take photos with the wingman removed. However, I can't get up there at the moment due to a leg injury.
I can send the same photos again to refresh your memory if you like.
