Ok I have a Jensen flip out and want to do the emergency brake wire to make it so I can watch movie, does anyone know how to wire that damn thing? I've tried numerous things and never had any luck with it, any help would be appreciated

did you try just grounding it? my buddy has a kenwood double din and we tried a few things and the ground made it work all the time

yeah i tried grounding it, blindly putting in one of those codes like 100 times. i have no idea what is gonna make this thing work lol
