How do i by pass parking brake wire for indash dvd jensen vm9312 i'm puting it in old car no p.b.

Hi jason
To answer your question;
You do not need to connect that wire but you need to bypass the parking brake function in the menu.
Here`s the parking brake bypass procedure:
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.
Hope this help Cheers
