wiring diagram

I found these diagrams at mymopar.com

I have started rewiring with the harness that has the neutral safety switch, starter relay ground, what looks like the dryer pressure switch wire for the a/c (blue wire).

The diagram A above makes it look like this plug shares wiring with the wiper motor. The way they are grouped implies that anyway. The wiper motor is a different plug.

Also, If anyone would have any pictures of firewall wiring, routing, looms, ties etc., any good reference pics. I could use some help getting the routing back to normal or stock looking.

Thanks for any help!

On the firewall side, the wiper motor connector is separate from the (auto trans) neutral safety/back-up light switch and A/C blower motor connector. They are immediate neighbors at the bulkhead connector however. The dark blue A/C clutch/underpressure switch circuit wire is wrapped with the blower motor wire(green) but connects to cavity #20 in one of the other firewall side connectors.
