B16A swap wiring

I have a 94 civic cx, I have ordered an SiRII motor for it(complete swap). I think since my car has OBD1 wiring that it will plug in. but do i have to run any extra wires for Vtec, Knock sensor, exc....?

if your car is non-vtec now yes you need to run, i think its like 4 wires for vtec.. im not sure about the conversion i think you will be ok.. but im not sure

does anyone know the specific location the wires go on the ecu, and where they go?

the ecu should be on the passenger side under the carpet (in the front seat) somwhere around there and the wires go into connectors right on the side of the ecu.

which harness will you be using?? if using your cx harness
you need to rewire to a 4 wire o2 sensor, add vtec wires,knock sensor wire.

I have to use the cx wiring harness because the jdm wiring harness is for a right side driver. Why do I have to have a four wire O2 sensor when i only have a one wire sensor now?

thats just how they have it on the b series, you need to convert it or the ECU will probably throw a light about the o2 sensor if you keep it one wire....
