L-B racing

im putting a d16y8 in my 89 si and ive got everything covered except for the crank sensor. i figured out where the blue and black wires go. my simple question is, where does the white one go? i asked on the ef forum but those guys are to busy talking about baking headlights and body work. so if anyone can help id appreciate it. or if anyone reading wants to trade their obd1 dist for my obd2 stuff that would work too
