How do you tell if ecu is auto or manual?

[Superhatch]

I've got a P75 ecu out of a 99 RS Integra. I dont know whether it came out of an automatic or a manual Integra. I've had it sitting around for years and I've never used it. Is there some kind of distinguishing number or mark to tell which kind of car it came out of?

Post up the number on the side, like this one:

Ok....on the first line the numbers are: 37820-p75-a04
numbers on the second line are: 980-316232

I have an obd1 p75 if you need it.

Not 100% certain but it should be manual

88-91 ECUs (PM6, PR4, PW0, PR3, PM7):
5spd = 000, 001, 002, A00, A01, A10, J00, J001, C01, C00
Auto = J51, J50, A50, A51, 901, A60, C50, C51, X30, A80


92-5 ECUs (P28, P30, P61, P72, P91, P08)
5spd = 000, 001, 002, 003, A00, A01, A02, C00, C01, C02, J00, J01, J02
Auto = J50, J51, 901, 902, C50, C51, C52, A50, A51, A52

96-00 ECUs (P2E, P2P, P2J, P72)
5spd = 000, 001, 002, 003, A00, A01, A03, C00, C01, C02, C03, J00, J01, J02, A11, C11
Auto = A70, A71, A72, A91, A92, C70, C71, C72, C91, C92 From the patterns we can learn the following:
-First letter = country of orgin
J = Japan
C= Canada
A=USA -Second digit, if 5, 7, 9 then ecu is auto usually
