I screwed in another Adel clamp placed around the second wiring tube from the left. I drilled a #19 hole in the F-607 bulkhead and also in the EDC-10A bracket. I used #8 cap screws and nuts to attach Adel clamps for holding the OAT wire and the EDC-10A wire. I ran RG-400 wire for the marker beacon thru the left outboard tube. I crimped a BNC connector to the aft end of the wire.
