Question about 2003 Chevrolet Trailblazer Ext
I need to figure out how connnect a parking wire of the dvd player to the negitive gound of the parking brake light????
On the parking brake under the dash is a switch at the top that actuates the parking brake light. On most vehicles most are two wire switches, but some are one wire switches. If you have a two wire switch then you can unplug it and use a test light with the ignition turned on without starting the vehicle and test the wires to see which is the hot wire and then connect to the one that has no voltage on it because it is the ground for the switch. The wire is used to detect the parking brake position as engaged before it will allow viewing of the DVD player when the vehicle is not moving. When the brake is off the DVD player will not play DVDs, this is a safety measure so the driver will not be distracted while driving. Good Luck, RAC
