yes, my ecu page, see the list of all ecu's shows that all things same, the 3sp and 4sp ECU are same
but i cant answer for the all things word.
look at this list please. (ECU's there are many)
2 links here, covering all USA an Canada, ECU ( and Puerto Rico)
all of them
see Real ECU here;
http://www.fixkick.com/ECU/ECU.html#EPC
lets pretend you want to swap a 95 and 95 ECU, from 3sp to 4sp (just ecu)
Note page does not mention 3sp and 4sp, that is because they are the same , with is not same
are the other criteria
engine type. 1 injector or 4
there are 8, 1995 ecu , in N.America, and way more world wide, (smog parts,4wd/doors/MT version, and Ecode markets)
you tell me the ecu you have now, p/n and can answer way better,
the ecu has a tag and an number .
looks like this.

(harness question are even more complex. short answer all are different, by trans, body door count, engine, 2wd/4wd, lots and lots of harnesses.
ill later to day ,do a harnesses EPC look up.
this is the most hard question of all, (vast harness configurations exist)
but will try. 3sp and 4sp, swap. (not m/t as we already know its wont work at all)
try to understand the car comes in many forms, not just 3 or4 speeds
2door
4doors
8v
16v
2wd
4wd (and all permutations there of)
MT 5sp
AT 3sp
AT 4sp
all those. cars run different parts, and harnesses tops this list. (and matching ECU.)
mixing parts between them can be hard work.
lots of home work !
and smog rules. (smog parts change by country and state, EGR tops list and EVAP)
The ecu is also tuned for the weight of the car, (door count tell it that)
also expectations come in to play.?
1: passing a smog test>? on pre 1996 cars in usa is super difficult (low VW today) the pre 96 bet the rolling dyno sniff test here, IM240 tests.
2: just runs ok, dont care if CEL lamp warning glows all day. and code 51 DTC errors. all day.? (ecu might run funny like this in USA only)
3: might have flat spots in the throttle due to ECU mismatch or smog parts not right matching ECU and harness? (EGR tops this list)
4: car moves and shifts gears, 1,2,3, or even 4, (or ok to skip a gear?) (is home made manual shift'er ok? on 4sp,. hummmmmmmmm)
5: car moves shifts all gears automatically. but TCC don't work., (m/t to 3sp this is what you get)
6: some cars have ABS and 4wd and ABS WORK TOGETHER.
7: Some cars have RWAL (rear wheel antilock brakes) and works with ECU and and 4WD modes... (goes off line in 4wd it does) (danger if not)
exceptions, are never known unless stated.
in the usa, finding a 3sp is like this
find a 2door, most have a 3sp. if not m/t
the short car is lighter and runs the low torque rated 3sp.
2doors. most have it.
the 4dr have 4speed, here.
outside usa, lots of other mixes....
