At first I was not going to use the GAD-27 interface to control the lights, flaps etc, but now that I am I need to change the switch wiring for these functions. The main power for these fuunctions go to the GAD-27 directly and the switches just work as a simple grounding switch to tun the function on and off. Flap switch as well needs to be rewired, no need for positive power lead, just a switch to ground function for up and down movements. Worked on the main harness as well doing some lacing and cleaning up the spaghetti
