Which crank trigger goes to which wire

[RichHawk]

1987 911 3.2L Stock Motronics system. Getting ready to put the engine back in.

I had a lousy loose label on the wires that connect to the two crank triggers and the head temp sensor. When I pressure washed the engine bay last week, I blew the label off.

I know the engine won't run if you mix up these sensors. I'm hoping someone can guide me on how to identify which wire from the body goes to which sensor?

I kept the wires on the engine side in the correct positions on the bracket (Pictured) that bolts to the intake, so I'm hoping that Porsche kept the orientation correct AND hoping that the body wiring is somehow identifiable without tearing things apart.
The closest I can hope is that the two white wires shown below are always in the same orientation, left to right, in the factory wiring loom.






Can anyone tell me which body wire is the speed sensor, and which is the reference sensor?

Thanks,
Richard

I moved this over to the technical forum, as it's not directly part of the rebuild.
Specific question here if you can help me answer I'll be most grateful.
Which body wire is for the Crank speed sensor?

Thanks,
Richard

Bottom black one is the ref sensor
Speed sensor in the middle.
Cyl head temp is the white one.

If it doesnt start with one way switch them, if thats the only problem it will be solved as they are both the same part doing different things.
