Default please help me identify ECU....

i was at the junkyard and went to pull the ECU out of a 88-89 Integra and noticed that the ECU plug wasnt connected to anything then noticed a ECU sitting behind the seat, bonus i dont have to pull it, but closer inspection revieals that it has a gray plug terminal (OBD1-2 right?) and is a PR4 ECU.
now im a Civic/CRX guy and all my other ECU's have a date stamp on them somewhere, i dont see one on this one. the PR4 ECU would be in every non-VTEC Integra from 90-00 right? how do i identify this ECU? and how do i know if its an auto or 5-speed ECU?

oh yeah the tag reads: 37820-PR4-A11, 490-104011, ABJ

I do belvie the PR4-aXX where the aXX designates the auto/manual config. I have a 91 pr4 taht is a manual and its an a10. 92-93 is a OBD1 nono-VTEC pr4 for the B18a1. You can convert it to stick. for example my ecu is:

37820-pr4-a10 (its the part number) the second half is hte serial number.
