Is the ECU for 93 WD21 4x2 the same for a 4x4 93 WD21?

the only difference is you dont have a transfer case

so, if i put an ECU from a 4x2 into my 4x4 it should work just fine? will the transfer case work with no problems?
IIRC you shouldnt have a problem, as the tranny would only be affected if going from a manual ECU going to a auto ECU (gear shifting types)
