the 96+ V6 IMRC controller box isn't hard to replace at all.
You remove the plastic "duratec" cover on the front of the engine (three 7mm(IIRC) screws) then the IMRC is visiable beneath that. Four screws hold that in (10mm??) and a plug on the right edge.
Remove the plug and screws, then trace the cable (that goes in to the rubber grommet on the imrc) back and down low in to the engine at the LIM (just below the Throttle Body/Air Intake)
Simply remove the cable from the bracket there, and replace with your new IMRC/Cable.
It would be EASIEST to replace it if you removed the Air Intake (you can leave the TB on the UIM, just pull the intake off the TB) SMALL hands might do it without removing the intake.
All of this assumes you ACTUALLY have a non-working IMRC, and the problem isn't actually something else. Let us know if you aren't SURE its the IMRC.
