... you probably could retrofit the trip computer fairly easily if you can 
get the switch and the LCD module out of the other dash.  Why would you want 
to put something in your car that isn't that likely to work well anyway?  ;-)

I'm not being totally facetious here ... you'd probably find that the resis-
tor that senses throttle plate position in the airbox isn't reading correctly 
... if it is wired in at all.  If you really want to do it I'd recommend 
checking the Bentley wiring diagram to see how it gets connected up and make 
sure that you pull these parts out of the donor.  I'd be surprised if your 
car didn't have the wiring already in place.  Hell, our '88 5kCSTQW has the 
wiring for the alarm system in it ... I doubt very many were sold with that 
option!
