Need help reading backup lamp diagram

[my5thmopar]

1972 Dart A904. I had the column lowered working on the horn stop lamp and time delay. Now my backup lights don't work. Everything else is still working. Fuse is good and so I'm sure I have a loose connection. What I don't understand is the diagram. Starting at the transmission switch. I see the B2B-188K terminating to a connector C and jumper-ed to D on bulkhead. But, now I'm lost because I don't see a connection on the next diagram. I'm guessing here but, does the ckt go through the column wiring or the other molex connector at the bottom of the column. Any help would be appreciated. Craig

Edit update went for ride hit brakes and horn sounded. Is this related. Also found better diagram and will review. Thanks

There were a couple of years there where the bulkhead connector diagrams were screwed up. Look for the wire number / color instead. I'll see what I can come up with, "stand by"

Pay attention to the 4 speed vs auto wiring, tho, which is a bit different.

Looks like one goes to Z where it turns to white in interior, from there to the kick panel connector for rear harness

In this particular case the A/B diagrams from MyMopar might be of help:

Also be aware, than "in through these years" there was a mistake in the bulkhead connector re: horn wire and start wire was a mistake.
