    Can't help on direct interchange, but once you get to OBDII systems (96 and newer), they're pretty specific. The replacement will have to have the same engine/trans, and may require a re-flash with the dealer for all the accessories to work right.

    thanks Bob, we got one from a 96 4.0 auto and it seems to be correct, the cruise control even works now where as it didn't before lol
