So I have a 2000 Si with a bad harness so I bought a 2000 ex harness and converted the cpk to the 2 wire. On the distributor plug the b16 has the big plug but the engine harness as the little plug. I converted the engine harness to the big plug to match using this diagram:

Is there anything else I need? I matched them up as per the diagram but I did notice the the big plug is calling for the blue engine speed output but it ends on the distributor plug and the engine plug is capped off? Any inputs?

Also will the OEM P2T ecu plug right into the ex harness and run fine?

Thank you!

 

What is this?

99-00 Civics do not require a blue tach wire at the distributor because they get the rpm signal from the ECU.

 

Sorry RonJ I ment CFK. The ex has a 3 pin and the B16 has a two pin so I just in pinned them with the old connector and left off the middle black one.

So I'll be fine using the diagram that I posted?

 

The EX and Si both have 2-wire CKP sensors.

I think you mean CKF sensor. The B16a2 is missing the black wire of the EX.

 

Yes you are correct I get them mixed up. Thanks for clarifying that RonJ. Any thing I should worry about using the ex harness? P2t will still run the engine?

 

RonJ what is the best solution oxygen sensor? The Si uses a different plug the the ex. The plugs are different and so are the part numbers...Are they still compatable?

 

Repin from your old harness.
