hey, my car is a 98 integra ls with a crv bottom and a gsr head. i am running a chipped obd-I p28 ecu with the conversion harness. i am throwing three engine codes:

9 Cylinder sensor
21 VTEC spool solenoid valve circuit
22 VTEC oil pressure switch circuit

do you think that the wiring is just done wrong or what? i have no clue where to start to fix this. please help
