early wiring help

[nuclearlemon]

have four wires on bosshogs rig we're trying to figure out. these are on a 1969 wiring harness on the drivers side apron midway down and we're installing a 1978 powertrain with 69 regulator, but 78 coil/alternator/starter

we believe we have voltage regulator, alternator, coil, horn relay, inspection plug, reverse light, fuse block, marker/turn/headlights, heater, starter wired correctly. we have identified the now dead 4wd indicator plug and the w/s washer plug. what we haven't identified are

single black/yellow wire with forked terminal approximately under the regulator (but we think we have regulator hooked up correctly already)

longer (6" or so) taped off pair of small guage wires with standard cruiser "T" plug setup with yellow/red and white/black wires, same location as above

3" or so paired wires white/lavender (which is normally ignition circuit) joined with a green/red at a forked connector, still same locale

lastly, just a bit closer to the firewall, under fuse block area is green/red and white/red joined at a forked terminal. white red should go to fuel sender system, green/red is often lighting. i'm pretty certain this goes to the fuse block for power to sender/turn signal flasher.

#2 looks like it goes to the transmission shift tower on my 6/72 pig. What's in the picture connects to 2 Red/Blue wires, with electric tape serving as a harness wrap here.

Possible wiring for #2

Line at my pinky goes off to transmission shift tower and emerges out of harness at my index finger. 6/72

6/72 LF engine bay inside apron

As for #1, this 6/72 is a completely different situation. Maps very poorly to your pictures.

i believe you are correct, after peeling back some tape, we had the reverse lites in blue wires, not green as thought. so we now have two blue/white wires with bullet connectors around the middle of the firewall but they won't be important to making it run, so they can be figured out later.

Bump. Still need to get these wires figured out ( the ones on the left inner apron area). Tia

Blue/White (LW) is usually washer motor pump in that location
The Red/Yellow (RY) and the White/Black would be for the VSV (Vacuum switched Valve
The two terminals with the forked ends connect to the fuse panel. The Green/Red(GR) and the White/Red(WR) both connect to the second fuse from the bottom of the fuse panel.
Hope that info is not too late!
