1987 944 Odometer not Working

Any ideas for troubleshooting the odometer on my 1987 944? Stopped working. Speedometer works fine.

Sir Klinker :) since you have been dissapointed with your earlier post, please find attached link that may just be what you were looking for...of course I would have gone on my normal rant and rave that it does this and that, but since you are only looking for a solution...ths will surely help
