The next project is to find a way to bring the wires to the rudder tail light (position and strobe). After considerable head scratching I decided to drill one hole in each of the rear bulk heads close to the bottom of the fuselage. Because the F-712E tie-down bar take up most of the lower part of the F-712 bulkhead I found a spot just to the left and close to the bottom of the tie-down bar for the wire entry hole. I drilled the holes to 1/2" and inserted the plastic grommet. Drilling these holes was a real pain, using all kind of extensions for the step drill. The next problem was that I forgot to pull and connect the position light wires. That was a real contortionist job. Now I have all the needed wires at the empennage (Position, strobe, magnetometer, elevator trim). Fuse828: Magnatometer, Strobe, Elevator Trim, Position Light. F710 Bulkhead. Fuse827: Strobe, Position Light. Between F710 and F711 Bulkhead. Fuse824: Strobe, Position Light. Back of F-712 Bulkhead.
