OBD0-1 conversion , Ign. Timing Adj. Connector?

[Arvid]

I´m done with a OBD0-1 conversion on my 89 CRX. Everything is working correctly with no codes, however I´m unable to find out where the Ign. Timing Adj. Connector is located on a OBD1 ECU. On the OBD0 ECU it´s located at pin B20 according to this link : https://hondaswap.com/forums/index.php?showtopic=29360

Can anyone tell me where this is located on a OBD1 ECU ?
