    On my 90 Silverado the trip odometer didnt work so I replaced the whole unit with a new one..odometer & trip
    Imight have reversed the four plug connector on the board... now the cluster lights dont work and the trip/odometer
    doesnt work. Seems like I''m doing one step forward two steps back.
    Anybody adept to cluster work on these 1990 relics?

    Have you tried seeing if the connector is backwards? Did you get this brand new or used? Maybe the one you got is bad?
