So I installed a switchback led 7443 (2004 TL) on the driver's side but seem to have probs with the passenger's side.

The passenger's side has 3 wires (as does the driver's side) but slightly different coloring. One is black, one is red, and one is white. I know black to be grounding but which is the parking light? The resistor needs to be tapped into grounding and parking but I seem to be having problems with the quick blinking rate.

So red or white for parking lights? I searched thoroughly on ALL the led threads and couldn't pin point which color.

 

The resistor should connect to the turn signal wire and the ground. Not the parking light wire. I'm not sure of the color, but you have only 2 wires to choose from. tap into the red one and see if that works, if not, just tap the white. Black is ground.

 

Oh yeah that's what I meant.

I installed on the ground (black) and white (probably parking because the blinking rate on the switchbacks have been equalized).

No problems.

 

Which resistors did you purcahse/use? I tried using the 50 W 6 Ohm resistors from V-leds and they don't seem to be working.

Where did you get the switchback led's

 

I did a search and found a few posts and read through them and used the links I found to purchase the switchbacks.
