Ran the wires for the tail light. The tail light is a Whelen A500 style that is a combination light with strobe. I'll be going with 3 strobes. It's overkill, but never hurts to be seen. The cut-out was made with both a left and right handed pair or Wiess snips. It was then filed to make the edge smooth. I used two different holes for the wires. One was for the shielded 3 strand that runs the strobe portion of the light. The other was for the single wire that runs the standard tail light. My thinking was that, if for some reason, either wire rubbed through its rubber grommet and shorted out on the metal frame, at least the other would continue to work. I attached the ground wire using a standard 18GA grounding lug that was placed in between the channel and skin of the rudder. Both pieces were sanded, and continuity checks with a multi-meter showed that there was 0 ohms resistance between the connector's ground and any bare metal point on the rudder. I saved about 12 feet of wire to run into the fuselage for the strobe power supply hook-up.
