97EKCRVtec

I'm currently in the process of swapping my B20Vtec into my 1997 Civic Hatch (CX) The motor is OBD1 (Orginally in my 93 DA) Obviously the Civic is OBD2a, I bought an OBD2a to OBD1 ECU Harness, and Repinned the Harness for the 2 wire IAC Valve, VTEC, and the Knock Sensor..
My question is... What all do I need to rewire/repin/redo on the CX Wiring Harness to make this OBD1 motor run correctly?
and should I run the CX Primary o2 sensor or use the o2 sensor from the 93 Integra?

What all do I need to (re)wire besides the Dizzy, Alternator, VTEC Soli., VTEC Pressure, IACV, Injectors, Knock Sensor?

Basiclly I'd like some help figuring out everything I need to do to make this motor wire up correctly using the CX Harness on an OBD1 Motor

Are you gonna run Hondata? You can use the CX Oxy sensor. You will need to extend the wires as Bseries primary O2 is farther away then SOHC. You dont need to rewire the Dizzy if you have a Bseries OBD2 dizzy.
Also if you run hondata (maybe others I only run Hondata) you can eliminate knock sensor O2 sensors ect, and not have to deal with the wiring. However will be hard to pass DEq when the time comes.
I converted my whoole motor to OBD2 then just bought a OBD2-OBD1 harness. Wired up VTEC, IACV and extended O2 senor

That help?

Yeah I'm running the S300. Thanks, I wasn't sure about the CX o2 sensor..
I already have the Knock Sensor pinned and wired up so I'm okay on that.

The only thing I'm not 100% sure on is my MAP sensor, the cx harness has a 3-wire map plug and my motor is using the 2-wire MAP, I honestly haven't looked around much on what I need to do to fix this. Got any ideas on what I need to do? I'm guessing that the 3-wire map is Positive, Ground, and Signal wire? and the 2-wire is Positive and Signal?

My car will pass PA Inspection, but it won't pass PA Emmissions since they plug the machine into the obd2 service port, But I got a friend who does Inspections I'm sure he'll pass it regardless.
