the ECU tag on 91 looks like this, if 89 the 56b is 60A coded.
see the US mark for USA, this means it runs USA smog devices. THAT "AT: mean for automatic trans, yours will show "MT" for manual trans.

we need to know this so we can see what degrees the last own swapped in wrong parts. (desperate for sure)
now if learn 91-98 sidekicks well this funny list makes sense, this is my 89/90 differences page and is prime information on why wrong parts work wrong.
The early 2 years have vast differences, they look kinda same but see here.
