Got around to finishing some wiring tasks in the tunnel. When I installed the ADAHRS unit, I secured the wire cable with a zip tie—just didn’t look right. So, into the tunnel I went armed with a right angle drill attachment, adel clamp, screwdriver etc. Opened the existing hole where the zip tie had been and installed an adel clamp. Also added a stick on mounting block to secure the OAT wire that connects to the ADAHRS unit. Wiring in the tail cone looks much better.
