Trying to follow the Large Yellow #50 wire from the ignition to give power to the starter solenoid. I've had to re-wire my car - it was a burnt out interior and doing an engine swap. When I tested a large wire that I believe to be headed to the starter I only get 5.4 volts - not 12v. I may be wrong about the wire but it comes from a branch as pictured with two wires coming in and two going out (first 2 photos). My ignition has only 1 yellow wire at #50. As described in SpiderMike's post:

the only difference is the yellow wire at "R" is not yellow on my 86 but green (as pictured in the 3rd photo probably because my 86 is a late year build with 87 wiring perhaps).
Is there somewhere I can trace the yellow wire out of the ignition. It goes into the bulkhead and into the large wire loom but other than my first two photos not sure if that is the wires. Also not sure what type of connector is shown in the first two photo. I think a wire goes into the smuggler's box to deal with shutting AC off when cranking as picture in the 4th photo. Perhaps Timmy2 or Spidermike can chime in.
