just a quick question about ecu interchangeability....

[thesupragod]

Will a turbo 5 speed ecu from a 1990 work on a wiring harness on a 91 or 92?

Thanks in advance for any input!

im not sure but your supposed to match them so you wont run into problems. sorry i didnt really help.

Yes the TCCS should be just fine. 87-88 are the same (yellow plug) and 89-92 are the same (gray plug)

'89 isn't the same as 90 and '92. '89's change mid-year. You should always treat '89 cars as their own special bucket of bolts.

Early 89's often match 86.5-88 cars, even if they have gray plugs. Late '89s often match the 90-92's.

it should work 90-92 have gray plugs.

If any of you have a 91-92 turbo 5-speed ecu that you are willing to part with... Let me know!
