Wiring

Does anyone know which fsm I should use on my 69 300 that was made Nov 68?
I have the 69 manual but I've pulled apart most of the wiring harness and the wires don't seem to match.
I started to trace and repair no backup lights. The 69 fsm shows the black and black w stripe from the trans to the fuse box. Good switch good ground, no lights. I pulled apart fuse box and it shows wires changed to white w/ white stripe inside fuse box. Fsm shows white going to purple wire at floor sill and purple wires go to back up lights. No circuit. Fsm shows purple wires change to white then go through fuse box. Simple circuit. Trying to trace two white wires, they go up into dash and I pulled dash and still haven't got to end of white wire. Fsm does not show all this.
Back up lights have good ground and work fine if I jump power to purple wire connector at drives kick panel.

The 69 manual is the correct one, I have found minor errors but generally they are correct.

Show a copy of the page and highlight the area you are looking at.

Just trying to get b/u working. I'll send it soon as I can. Just about got whole harness out haha. 3 days for a dang light.

The trans has the 3 wire switch and neutral switch works fine. One side of b/I switch and other side hot. Can't get lights to work or find which leg is not working. According to fsm switch closes and completes circuit but even operating another switch by hand and grounded. Lights won't come on. Don't think it would be switch or trans since neutral switch works

Mess haha

Ignore the heavy red marks. They were in book when I got it.
Diagram shows white wires coming into and leaving fuse box.
Diagram shows connector and turns to violet on other connector.
Hots and grounds and fuses test good in fuse box. Lights work when applying power to violet wire.

I think someone did some rewiring.
Before pulling everything apart: I would Check continuity from reverse prong at the auto trans 3-prong switch to the fusebox to determine whether you have ground. Then check continuity from the backup light socket to the fusebox. I would want to know which side of the circuit is the problem.
