i have a customer that had me put a N1 in and grounding the eBrake didnt work. now i see you have a mod for it on here, but i dont remember ever doing this years ago when this came out. and ive done a lot of these N1's to. will a switch do the trick also or will it still cut the video out after a certain speed? and i thought i remembered something about running your video out into the camera input.
