Hi i got a 91 integra with a b16 in it. I still need to wire the vtec into my ecu. I have a PR3 ecu. I was looking at the conversion wiring, and for pin b19 it says it is supposed to connect to the knock sensor. on my integra there is a wire going there already for a P/S pressure switch(dont have powersteering in my car anymore). Do I just cut the wire and and tape it up and connect my knock sensor wire to the ecu? And for the 2nd 02 sensor wire(my car only has 1 02 sensor) can I connect the wire on c8 to the c8 pin and the c16 pin(just like run 2 outputs from 1 wire?) If you dont understand me trying to explain this message back and I will try and explain it better. thanks Dan I also found that wiring for a trailer works well for wiring vtec(4 wire harness) can be purchased at home depot, lowes, rv sales, etc..
