LED BLINKERS - Help

[BenzMeister]

I bought two LED's for my 99 C280 for the front blinkers and parking lihgt. When I installed them they were very dull. I went back to the store and both 2 resistors. Now my questions is the resistor instructions say to connect one wire to ground and one to the brightest light? I believe the blinkers are brighter then the parking lights. The wire harness has 3 wires 1 black with a white strip, 1 gray with a white strip and 1 brown. Does anyone know with line goes to the blinkers and which is ground? Many Thanks!

The brown wire is your ground. Now you you gotta find out which wire is for your positive between the black and gray.

As long as I know the ground, I can use a strobe to find the blinker, for some reason I think it is the black and white wire, I'll let you know if I'm correct.
