Question about 1999 Buick Regal
The back end of my car was hit by a plow and I'm trying to make it street legal by replacing the one light that was smashed up bad (rear L turn signal). I bought a stand-alone turn signal from Wal-Mart with two wires (red and black) coming off of it. The wiring harness to my car's original taillight had three wires (black, green, brown with white stripe). I have no clue how to wire this up because I can't figure out what color is what (I assume one is the ground). Originally the new turn signal worked except was blinking fast as it normall would if one of my turn signals on that side was dead. Then I rewired it at which point it was blinking at the appropriate speed, however when I got back into my car I noticed all of the lights on my dash were dimming in sync with the blinker. I'm sure I have the wiring wrong or I'm not finding a good ground or something. The other thing is that there are two more wires that came out of the harness that originally went to a small running light (black and brown with white stripe). I didn't hook those up at all because I wasn't going to try to replace that small corner light. Would these symptoms be caused by having those wires not hooked up to anything at all? Any help would be much appreciated
The Light has SOMEWHAT 3 Wires The EXTRA IS The Mounting Bracket IT IS The GROUND now thet light to see white or brown is TAIL Light or Turn GM's Usualy USE BROWN as TAIL LIGHT that would Make the Only WIRE Left as Turn SYGNAL..you may not need to GROUND New Light to BODY the Black ic a Body Ground ALREADY GROUNDED Good LUCK

You should just be able to find a hot wire 12v most likely the black wire, the ones with stripes are most likely tied in for trailoring lights. If there are only two wires 1 wire can go to a bolt or other bare metal to ground. You have a test light in the light itself, wire the 1 wire to a good ground and with the other end of the light wire touch to black wire with the appropriate turn signal on and when the light blinks in correct rhythem than viola, you have the correct wire. Direct current operates thru the light it doesn't have to be hooked up to alternate back to the power source like A/C. You could dissasemble the good/other turn signal and see which wire goes where, but with double element bulbs it is a 50/50 chance on which one is the turn lamp or the brke lamp. good luck.
