1992 Bronco digital odometer -- help!

Hi all,

This is my first time posting here, so forgive me if I ask a questions
that seems obvious. I just purchased a 1992 full-size Ford Bronco
Custom, and the digital odometer doesn't work. Everything else is
functional. Is there a specific fuse or relay that I can check, or do
I need to replace the gauge cluster to fix this? Please feel free to
email advice directly to the address listed below or to post it here.
Any help is greatly appreciated.

Thanks in advance,
Mike Berger
