The Generic Electronic Module is a PITA...
Disconnect the battery ground
Remove the steering column cover
Remove the bulkhead electrical connectors from the (B) instrument panel fuse junction panel.
Remove the instrument panel fuse junction panel bolts and remove the interior fuse junction panel nuts.
Disconnect the GEM electrical connectors from the GEM.
Remove the screws and the GEM.
After replacing it may take some driving to get it to act like it's supposed to... then it'll be alright after the "relearning".
