I wonder if that is pissing of the computer ?????? Is there anything on the factory pcb (inside tail assembly) besides traces ( capacitors/ resistors ) ???? Maybe the computer senses that ???


what is confusing is i KNOW im getting voltage to the Left bulbs (they work fine) ..........and im clipped right to that...to the Right bulb........thats baffling me


Yeah. What happens if you swap the left tail light to the right side then? Just to hook up and try that is.
I've never bought a new tail light but would have thought it would be identical to the old one and still use that board part. Maybe that's the problem? Unless it was having issues before?
It knows when a light doesn't work so maybe somehow the setup on the new tail light is messing with the system somehow?
