Just purchased the alpine unit.Everything works except the video.I have searched and read about the pac-7 module.I will order it but in the meantime i wanna hook it up with a toggle switch or just directly to the foot and parking brakes.I just wanna get video for now.The car doesn't have to be moving.I have a 2003 F150 where is the reverse wire located as i know you can hook it up this way.Also on the foot brake i have 2 wires coning out.1 is blackThe other is GREEN/ red.Which wire do i use.

the bypass will not work with a toggle switch on the foot brake. The unit must see the polarity change. The brake wire is lt green (+). You won't need the reverse wire.
