Fun fact: I just noticed that the RGBS cable that comes with the GBS pcb, is the perfect size for the kick harness header on the Minigun...just a couple pins extra. Good to know!
Another question...how would I correctly wire up a kick harness for the Minigun header pins? Like orientation-wise? I can easily find pinout diagrams for specific pcb's, but is there a pinout diagram for the Minigun?
