P72 is OBD2....you need a P28

uhhhh, ding, you're wrong...


There are obd1 P72's.


I can't remember the coding, but looking at the plugs is a super fast way of checking it.

as stated, there are obd1 p72's.
look at the plugs. each connection should have 2 rows of pins. if there are 3 rows, it is obd2.

quick google search says it is an obd 2a gsr. but looking at the plugs will definately tell you.



top to bottom
obd 2b
obd 2a
obd 1
obd 0

yes the OBD-1 P72 is a 94-95 integra GSR ecu look at the clips if it has 3 sockets then its the OBD1
