I installed a 2000 DX head onto my 1990 D15B1 (STD hatch) with a '90 Si intake manifold and computer. I am wiring the computer per the DX to ZC wiring outline on the Hybrid board, but I am having trouble finding the "Cylinder Sensor" to wire it.

Anyone have any clue what it is I am looking for????? Is it on the head or the manifold, and would the 2000 head even have it on there? Is it going to be a problem if I don't run it??

 

Oh, and I kept the D15 distributor on, will this work, and is it the reason I can't find it??
