I'm not quite sure how to wire them up so that they alternate when flashing. Anyone ever done this or know how it's suppose to be wired?? Even better does anyone have a schematic of it?

 

mine does that from factory when the parking lights are on, and when the parking lights are of they all flash at the same time....

 

I'm refering to wiring it up so that the signal and side marker alternate. Like when the rear turn light is on the side marker for that side is off, when the rear turn light is off the side marker light is on.

Your car did not come like this from the factory.

 

well... mine seems to have, unless its something with the flasher...

 

My car does that from the factory as well. Alternates. When one is on the other is off.
