I am new to this site so I am sorry if this topic has already been covered. Seems to me it probably is but I dont know where to find the info .I have an 04 325I. The rear signal light plug melted. I went to the dealer to purchase a new bulb assembly and plug. They gave me a copy the upgrade bulletin which requires installing a new ground wire to both right and left side assemblys. I purchased the parts to complete upgrade. The instructions were a little vague. Has anyone performed this upgrade. It seems simple if I can figure out where to attach the new ground wire to the car or into the vechicle harness thanks Rod
