Bulkhead wires difference between '71 Dart and '71 Demon?

Mattax said

Looking at the plymouth version, the rallye instrument cluster and standard instrument harness switches the cavities for the horn and starter wires. Looking at the engine diagram, that may be a mistake in the instrument harness drawing.
Here's where it is best then to compare with what is on the car.

Yes Mattax, you're right.
As I have to replace my dashboard harness, I will compare the new one with the old and invert the two wires if necessary.
Just wanted to find an explanation.
Probably a difference between standard and rallye clusters. Badly documented in Chrysler wiring diagrams

Thanks a lot
