Long road trips often require a little more in-car entertainment than others. DVD players located in the vehicle's dash are an ideal spot to play back video content for passengers wanting more than a book or music to pass the time. Very often, car audio manufacturers default on the side of safety, assuming that irresponsible drivers will watch a movie while driving. Simply bypassing the parking brake feature by grounding the brake wire ensures that responsible adults can enjoy the video system they paid for to its fullest extent.

Skill level:

Things you need

  • Wire snips
  • Insulated T-tap connectors
  • Crimp tool
  • Video unit's manual

  1. 1

    Locate the black ground wire and the unit's parking brake wire. Consult the unit's manual if the parking brake wire is insufficiently labelled.

  2. 2

    Snip the parking brake wire using the wire snips, halfway up the wire. Strip 1/4 inch of insulation from the radio end of the wire.

  3. 3

    Slide the male spade portion of the T-tap connector over the bare wire. Crimp it in place with the crimp tool.

  4. 4

    Snap the tap portion of the T-tap connector over the black ground wire, aligning the metal teeth in the connector with the wire. Press firmly until the clasp engages on the connector. Wiggle the connector a little to ensure positive contact with the wire.

  5. 5

    Slide the male spade connector into the female receptacle on the tap, until it seals firmly.

Tips and warnings

  • Although it's possible to attach the parking brake wire to a toggle switch, newer head units often reset themselves after toggling the switch. By attaching the brake wire constantly to ground, the DVD player always thinks the parking brake is engaged.
