ok, all the documents on how to wire up your b16a1 into a 4th gen si say that you need to extract the pins from b5 and b19 and replace them with the vtec blah blah blah, thats not my question. my question is that when i unpluged the harness from the ecu i found that there were no wires or pins leading into b5 and b19 for me to replace.....Is this at all normal?
