Wow! 16 pages, I read most of it several times. I like pictures, please see attached. I found a picture of the Signal Stat 700 on-line. This mod should work, however the brake lights will over-ride the signal lights. That could be solved with relays. This requires modifying the switch. Remove the two black wires from the switch. Move the red right rear wire to the other end of where the black wire was, same for the Left rear white wire. Where those two wires were tie that point to ground. Add diodes as pictured. Connect the brake light with diodes as pictured. The diodes on the brake light circuit will prevent the flasher from crossing to the other side. The diodes on the signal lines will prevent the brake signal from illuminating the front bulb when the switch is on. Also attached a picture of the stock left turn position to understand what is going on.
