swapping ecu's help

I am doing a 5-speed swap in my 92 ls h/b.The ? is can I use a 90 or 91 5-speed ecu?Im lookin on ebay and some say 90-91 / 92-93 but then some say90-93?I need a real answer.thanks... p.s automatic sux balls

either will work... but the 92-93 would be best to get if possible

isnt the 92 an OBD1 and the 90-91 an OBD0 so u will need a OBD1-OBD0 harness?????

Yes go with the 92-93 ECU

Thanks everyone .92-93 it is.
