Made up the brackets for the wing root connectors. The right wing will have a large CPC for the data and a molex for the lighting wire. The left has a much smaller CPC for just the pitot sense and OAT probe and a similar large molex connector for lighting and the pitot heat. I am also making an accommodation for coax in the left wing so will provide an adel clamp just in case. Marked and cut and bent some scrap aluminum plates to make the brackets. Laid out where the connectors would go and started drilling. Need to get a larger step drill bit for the large CPC on the right wing. Proceeding with the left wing. Got the CPC drilled, then marked the adel clamp location and marked the molex connection. Predrilled the corners of the molex then used a dremel wheel to cut the opening. Finished it with files. Fits good. Running a piece of the Vans conduit in the left wing for potential coax. Using shark bite clamps to secure to the ribs. They're a little big but wrapping the conduit in six wraps of electrical seems to work well. Marked on the inboard rib where the center of the adel clamp would fall then tried to center the conduit on that point. With everything clamped tightly in close proximity I shouldn't have to worry about chafing at the end of the conduit. Riveted the shark bite clamp in place. The rivets will preclude rivets in the middle of the connector bracket but can still fit four rivets total. Trial fit everything. Looks good. 9/26: got the pins all crimped and finished off the left wing root connections. Very happy with how it looks.
