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