Rally dash redo

Well another change.... radio wires...
68
White wire doubled up with red/tracer and orange (all 3 wires 18 gauge)
White > "D" cavity in b/h
Red/tracer > to "RADIO" hole in fuseblock.
Orange > #5 cavity turn signal connector.
67
Red/tracer 18 gauge > fuseblock
2 orange wires(18 gauge) doubled up, 1 wire> #5 cavity t/s connector.
2nd orange wire >round plug at circuit board(uh oh) for inst lamps.
Gotta think about this one. :BangHead:
Got nice fuseblock, b/h connector and dimmer switch plug from barracudakid so I think I've gathered all I need to finish up the harness. Keep coming across wiring changes :bs_flag:

Try to follow the current paths. Positive origin from -> to.
Power comes from the fuse box to the radio on a red wire. If white joins it and goes to 'D' cavity of bulkhead, does it join different color wire ( black or red again) in the terminal that takes 12 volts to the turn signal switch? Is there a wire outside that 'D' of bulkhead? I'm guessing not.
I don't know where 67 got 12 volts to turn signal switch. Could be directly from fuse box.
I'm pretty sure the wire from brake lamp switch to turn signal switch is white. They wouldn't have 2 of same color (white) going to that connector. So to pick up 12 volts at radio connector with a white jumper needs to change colors and join the front signal wires etc... to/from the turn signal switch, (taped into same harness). Like I said before, they would move things around to simplify or simply to save a little wire.
Orange to turn signal switch connector is for a column shift indicator lamp. That may be common to all, floor shift or not.
I know the rally panel has 2 circuit boards, needs orange wire to both. In 67 harness there is a weld splice buried under tape where this wire branches. Maybe they got them from 2 different locations in the 68 harness to delete that weld splice.
I couldn't sort it all on a computer screen. I need printed on paper side by side to sort all these differences.
