ECU swap in a '90 lude

[Eaglesguy]

Hey all,

I need to changed my ECU in my '90 Prelude and I need some help figuring out which ones are compatible.

Currently the car has an 88 or 89 JDM B20a and a 37820-PK3-A00 ECU. I purchased an '89 37820-PK2-66## ECU only to find that the mount points are different, as well as the connectors on the side. I was looking at getting a 37820-PK2-A00 from a '91 and was wondering if I will have the same problem, or if it will be exactly the same as a PK3-A00 with a possible difference in tune.

Thanks for the help.
