help Q for peeps with civic si's
i've done a swap for my ek hatch and I'm using an obd2b harness which works fine with my b16a2 swap. my question is my harness did not come with the hard wiring for the second o2 sensor. so i had to transplant the wiring from my dx harness. is the second o2 hardwire on the engine main harness on si's or is there a sub harness within the chasis? this is my first post and i'd aprreciate the help. thanks in advance.
