I've got the same problem with my 1986 300 SDL. My plug center "D" shapped center piece is broken off. I know the allignment is off. Previously my climate speedo / odometer wasn't working. The climate control was working when the key wasn't fully engaged. When the key was fully engaged, the clomate control worked intermittently.

After rotating the plug on the rear of the cluster, the speedo still isn't working, climate control works much better (but not perfect). The radio, and accessory light aren't working. Can someone offer some suggestions. Maybe even a picture of the attached plug at the proper angle? I did find a diagram of the pins and their corresponding numbers. But there are no number on the circuit board to aling.

Sorry for all my babble, I was attempting to be clear and complete.

Ron
