Unless this works...Perhaps I need to browse a different section on this forum. heh
M/F Locate the black ground wire and the unit's parking brake wire. Consult the unit's manual if the parking brake wire is insufficiently labeled.
M/F 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.
M/F Slide the male spade portion of the T-tap connector over the bare wire. Crimp it in place with the crimp tool.
M/F 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.
M/F Slide the male spade connector into the female receptacle on the tap, until it seals firmly.
M/F 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.
