Default 98-99 CL & 98-02 Accord OBD2B ECU pin-out

This is a OBD2B ECU Pin-out for the 98/99 Acura 2.3 CL, should be exactly the same for 98-2002 4cyl Accords.

Great thread thank you.
After many parts replacement (TPS, MAP, Injector, distributor, plug, plug wire, compression test and some more) today I found the culprit is an intermittent issue on middle-green white cable on MAP socket.

Question: can I safely rewire both 1. from MAP socket to body ground and 2. From ECU pin to body ground?

Thank you.

Hey man I know this thread is over a year old, but I'm such at the same spot as you were. I'm trying to swap harnesses in a 97 to the harness used on a f23a1 but don't see any pin outs for those two grey connectconnector information on your solution would be greatly appreciated

97 style plugs newest the fuse box

97 Again

98-00 ish that fit f23a1 harness

F23a1 plugs

Any help would be greatly appreciated, I posted this question in my thread I started when I first began this swap journey. Like I said any information would be appreciated.

Did you ever figure this out? Doing a swap from auto to manual on a 02 my harness is from a 01 but c102 is different one is square one is rectangle? C101 and everything else plugged up fine
