    I just purchased an oem dvd player and while it was being uninstalled it was cut from the head liner above the drivers side by the vent ducts. I know the harness has 3 wires. Can someone help me configure these wires as well as letting me know if I have a sunroof will the mounting bracket fit.

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

Sonata tail light socket melted. attempting to replace with after market socket. red, green and black coming form vehicle.

If you have a test light or voltmeter, turn park lights on and find the one wire on vehicle that is hot-it will almost surely be red or green, as the black is surely the ground wire. Now on the new socket, you need to know this: If those bulbs are two filament bulbs (one filament for park lights, and the other filament for brake or turn or both) the brake light and the turn light will be brighter than the park lights. You can tell the difference in brightness, and the brake lights are always brighter than the tail (or park) lights.
How many bulbs are on this socket? Do you have 2-filamet bulbs or just one filament bulbs? Maybe you can figure it out by looking at the other side, see how or which lights are for tails and which for brakes.

Put a 12v test light on one of the wires with the key on the one that lights is positive. That goes to the positive terminal (coil has instructions Right?) of the new coil the othe negitive terminal will blink when you crank over the engine be sure to set parking brake and chock wheels for safety before cranking engine!

1989 chevy have brake lights when park lights are off but when park lights are on have no brake lights pulled the light cover off noticed that the middle buld was on which is for stop, tail, an turn...

Check the brake light switch on the brake pedal. Sounds like it slipped out of adjustment. When pedal is depressed, the button on switch will extend and be on to pass current to the bulbs.
Also, you need to figure out the tail lights: those two filament bulbs are for park lights and for brakes/turn signals. One filament is for the parks, the other filament is for both brake and turn signals. American cars have the brake lights wired through the turn signal switch- from the brake light switch on the brake pedal to the turn switch, and then out to the rear bulbs for brakes and, or turn signals.

I had the dvd player/radio /cd player replaced in my 2007 Yukon, the cd player would not read discs, the dealership ordered a new radio & now the dvd player reads disc region error & will not play...

If your using copies then some dvds wont read them even if the old one did, sometimes its a gamble if it reads or not, if your using a master then i would have them check it out, it may be bad or need programing, it funny because sometimes it will play a copy and sometimes not, thats what i've run into. hope this helps.
