b18c1 (gsr) swap into a ek wiring diagrams!!
THIS IS FOR: everyone who wants to keep the obd2a EX harness and install a gsr! it shows the wires you will need to unpin, solder, and cut! i just finished this a few minutes ago, and i listed ff technet as a major contributor!
-However!! Those who do not already have vtec on there harness will need to look else where, because i dont need to run it so i didnt make a diagram-

Just to clarify but this diagram is intended for someone who does NOT have the OBD2A EX harness correct? EX harness users would only need to perform IAB wiring and secondary O2 wiring I believe. If so, please specific so as not to confuse everyone.

Curious... what's the point of the CKF and crank sensor wiring? When I did mine, I don't think I messed with those at all... If I remember right, my EK y8 had knock and CKF and I just plugged them in. Never threw a CEL for them.
I did however, have to swap pins B16 and (if I remember right) B15 for the fuel pump relay, or else it wouldn't start. This is in a 2000 car with a 2001 B18C1, and staying OBD2B.
EDIT: oh, didn't see you were talking about OBD2a cars.

Ek hatches did not come with downstream plug under the chassis. only the ex came with it. the ek hatches are on the dx harness.
