The Repair
The diagram below is the left rear lamp cluster for the 900 sedan. Only part of the circuit is shown for the repair. At point "A", drill a small 1/8" hole through the plastic to allow a new ground wire into the cluster. Attach the wire at point "B" with a small self tapping screw. Route the wire through the newly drilled hole and the attach the other end of the wire to any good ground point on the car frame.
