Got my rig back last night. Taillights worked again. It looks like they simply replaced the connector and wrapped tons of tape around it. Oh well, at least I know where the problem is, if the taillights go out again
On the subject of taillights, I noticed that all the upper round ones are foamed in on the back. How do you change the bulbs on them? Do you simply pull them out from the outside? The rubber gaskets seem pretty tight and am concerned that the wires might be foamed in too, preventing pull-out of light.
