Okay, where are my 904 Torqueflite wiring experts?

I downloaded the factory parts manual for 1974 and there's no guidance that I could find about this harness and its clips. Here's what I believe is factory correct: This harness comes from the bulkhead disconnect in the engine compartment and travels to the passenger side of the firewall. There, it has a plastic rectangular clip taped into the harness that allows the rectangular slot in the plastic clip to fit into one of those bendable tabs welded onto the firewall. This holds the harness to the firewall. From there, it descends to the first clip which is attached to the circular hole in the mounting ear molded into the right front of the aluminum bell housing. This clip is an odd looking squarish clip with tabs that fit into the hole and has a round keeper at the top that the harness passes through. The harness then travels up and over the bell housing and passes through a clip attached to the top of the bell housing where it bolts to the engine. This is a simple clip with a rounded loop at the top that holds the harness. Finally, the harness travels back toward the left side where it plugs into the neutral safety switch. At this point, it passes through a final clip - another of the odd rectangular ones just like the one on the passenger side. This final clip fits into the hole in the flat ear that is molded into the case right next to the neutral safety switch. Anybody want to weigh in on this? BOB
