Where to wire the e brake so i can have video

Use the parking break bypass procedure, and there is no need to even hook up the break wire.
The parking brake bypass procedure is as follows:

1: Go into AM/FM mode
2: Hit "setup" on the remote control
3: Enter 543210 on the remote, listening for the beep for each number entered
4: A new menu will appear. Touch the button that has the hammer/screwdriver on it in the upper left-hand part of the screen.
5: Select Brake bypass to "ON" and hit the "X" near the bottom of the screen.
6: Use the unit wisely and above all safely. A ticket is one thing, causing a fatal accident due to negligence is another.
