Hi Joe,

Yes. I took one from a '86 4kq and put it in my '85 4kq.  You need to
remove the trip computer's switch harness in one piece.  Don't cut off the
end connector or you'll regret it-the wires are all grey and took me a
while to get them connected correctly.  You'll also need the ecu from the
same car.  The ecu has some outputs necessary for the trip computer or it
won't work correctly.  The good news is that the harness from ecu to the
trip computer's function switch is already there-red connector with 4
leads-just tucked into the harness jungle behind the relay mounting frame.
Just fish it out and plug the trip computer's switch harness into it.  The
2 pin connector for the cruise control moves to a new 2 pin connector on
the trip computer module (was located next to the speedo cable).  Virtually
plug and play.  You'll probablly have to calibrate the display for actual
MPG.  The default setting gave me something like 33 MPG-its really more
like 24-25 MPG.
