how do i identify the pin #'s on the ecu.

If you have a 98 ex, you look on the back of the plug with the wires coming out, and the side with the push-in release is the top. On a 98 the #'s go from left to right to the end of the plug, and then continues left to right on the bottom.

1 2 3 4 5 6 7 8 ...
15 16 17 18 19 20...

92-95 obd1 is like this

1 3 5 7 9...
2 4 6 8 10....

Hope that helps!!

 

but there are 3 different plugs, each with there own set of numbers.

 

92-95 Civic/Integra
