Install went fine. All is working great. No tail strobe on that year. Sure did not take an "hour", more like 6 if is you first time. Biggest work around for me was getting something for the strobe housing to screw into. I will put some pics down below. Question I have is right now the yellow wire is not attached. Given just wing strobes, If I attach both yellow wires- the sync wires, how does the "brain" know how to sync them? Just curious, I am guessing the old power packs took care of that job. Is the circuitry built into the strobes? Does the yellow wire just interrupt the ground for a split second?
