ECU`s

Hey, i was wondering if anyone could tell me what these 4 ecu`s are from. I have a 92 rhd and i know 2 work in my car, 1 doesnt, and 1 sorta works. Heres the PN for all of them:

N3A1 18 881 (heater controls dont work, and idles funny)

N3Y7 18 881 (works good)

N3A7 18 881C (works good)

N3F1 18 881A (dont fit, harness connectors are different)

Any help would be great

Thanks

N3A7 18 881C is the one that belongs to the your 92 JDM, same unit was in mine.
Federal/USD are different than JDM, main different no EGR, no CEL ++++

Just for reference, but don't quote me:

N3A1-18-881(a,b,r etc) (Federal 93)

N3A3-18-881 (California 93-94)

N3C1-18-881 (Federal 94)

N3E1-18-881 and N3D1?-18-881 (95's)

N3F1-18-881A? (JDM 96+ Series 6 or 7)

Replacement ECU:
N3A1 18 881R ECU (Federal 5-speed)
N3A2 18 881R ECU (Federal Automatic Transmission)
N3A3 18 881R ECU (California 5-speed)
N3A4 18 881R ECU (California Automatic Transmission)

N3Y7 18 881 I believe is a European ECU, so use the N3A7 18 881C or buy a aftermarket like a PFC.
