The engine sensor harness has several black wires. Appendix C in the manual shows what sensor each of these black wires connect to. The only way to determine which black wire goes to which pin is to actually do a continuity check on each black wire (since the color coding is identical). When I connected several engine sensors, I assumed that ANY black wire could be used on ANY sensor that required a black wire, since ALL of the black wires were connected together internally in the EM. Is this true? If it is, then the wiring I have done should be OK. Appendix C (which was not yet in the manual when I did some of my wiring) seems to disagree with this logic, showing which sensor each black wire should go to. I am presently unable to perform any functional tests of many of these sensors since I am some months from being able to start my engine for the first time.

Thanks,
