Speedometer Replacement/Cable/Horrible Day

The small black wire about halfway down the column? It attaches the column to the dash just for grounding purposes. So just hook it to one of the bolts on that side that held up the column.
yes, you should actually have 5 nuts to bolt the column to the dash. nut / wire ring / nut on one of the studs.
and incase it wasn't totally clear, DISCONNECT THE BATTERY before moving the cluster. sometimes you can get away with not shorting the ammeter studs on the dash, sometimes you don't :oops:
