Good stuff. That Youtube fix should hold up too, especially with LEDs. Might help the new guys if they could see the crimping process. A short segment of video is repeated around 3m45s.

Have the same G.I. issue on the to-do list for my beater Taxi, plus some old operator hacks to deal with.

EDIT: You inspired me to work on mine. Found J6, the G.I. input, was also bad. Using the Molex 08-52-0113 .156 trifurcon replacement pins since they grab the header pins on three sides (still have incandescent lamps in this old beast).
