Help choosing Idle control valve

[Nuzzi]

Ive been looking around online to find a new replacement idle controller before I plug in my new ecu. The problem is they are all listed as direct replacement for all years '90-'94. I have a '91, and as far I know the 90/91+ are different...how are they listed as the same?

Assuming it's not the "pigtail" version of the ISC it's for your car. Lots of 90 owners are switching over to the 91+ version and extending the wires to accommodate for the lack of pigtail on the new version.
