You mean the factory pcb inside the tail light assembly?

The left is factory----works perfect.

The right assembly is new and doesnt have a pcb----just wires right to the bulb sockets that unscrew . Then new plug to factory plug

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
