EMS 220 DB 37 PIN 13 GROUND

[N125YX]

I've accounted for all the ground (black) wires from the DB37 both visually and ringing them out with an Ohmmeter, but there seems to be nothing connected to pin 13 on my factory harness (which according to the manual is supposed to be black/ground). I even rang out all the other wires. I don't think I have a problem, but I'm perplexed. Do I have a problem?

It's not any different than the other grounds (ie, you can use them interchangeably). So there's nothing functionally wrong about your setup other than your harness is missing a wire, which I do apologize for. You can sub any of the other ground wires for any sensor that needs a ground.

Thanks, on with wiring!
