that is what I diagnosed earlier... the Rambler's taillight assemblys are held in by the 2 screws that hold the lense on. there are 2 tabs on the back side attached to the body that the screws go into... I was testing, and testing and everything tested that it should work but it didn't ( this was with the lense off, and therefor a loose housing ).. went in here and posted the thread, then went back out and turned everything on ( with the lense/ housing fully attached ) and everything was working.
