I dont see a real need for the TCU in a 94 , the main benefit IMHO of the TCU is the first gear start (there is also a trimode out which is differnt but never owned those) and in a 94 you enjoy 1st ger start w/ the stock TCU.
The ECU installation is not so difficult even I can do it (which is sayign a lot), but it IS a bit of a hassle to get to it.
The below is for a 91 but it should be identical or nearly so for other model years:
1) remove kickpanel right in front of speaker on passenger side front leg room area (on right next to door). It pops out and there is also a screw.2) remove the glove box door3) remove the screws under the glovebox door attaching the kickpanel under the glovebox.4)Now you cna pop out that second kickpanel.5) with the access you just gained remove all the 10mm lugnuts holding the ECU to its bracket, alternatively you can remove it with the entire bracket.6) swap the new ECU into bracket being careful to put the connectors in evenly and at once (to not bend)7) install everything in reverse order.
I dont blame anyone who wants someone else to do it tho.getting the strings to loop over the clips just right to hold up the glovebox took me forever..:oface.
