Ok so my hmmwv wait to start light flickers faintly and erratically after starting if I move the shifter out of neutral it will not flicker it also flickers if I jiggle the shifter weather started or not. I un plugged the neutral safety switch and park brake switch and it still flickers if the shifter is jiggled not started. I installed a ground harness hopefully the proper way and it still does this. If it is a bad shifter and all electrical stuff is disconnected how can it still flicker jiggling the handle? unless I am missing something
