Honda o2 question?

[GSRteg®]

Ok i did an engine swap into my 93 cx hatch... I swap an OBD2 engine in. Now the question is do I have to do a 4 wire conversion to my one wire o2? Im asking bc I get a engine light and I checked it and it blinked only once, meaning o2... btw im using a p28.

Now here are the intructions on how to do it that I found on the net:

Using a P28 ECU (and should work for most obd1 ecu's with 4-wire controls) Run O2 Sensor signal (white) To D14
Run O2 Sensor signal Ground (green) to D22 (or any good Ground)
Run O2 Sensor Heater Circuit Control (black) to A6
Run the other black heater circuit power wire to (A25) or any good switched +12VDC source.

Ok you see that it tells me were to pin in the wires correct, but there are already wire in those slots... do I just splice them in with the one's already in there?

Any help would be good thanks for looking.
