Sorry I can't report that I know anything about the Virginian wiring and how it's installed but I do know that none of the wiring diagrams I've seen make any note of the tracers or lack thereof on the wires.
I had to make my own harness for my Allstate but luckily enough I had a used delapitated, faded one to copy and was able to identify which wires had tracers on them.
I make a spreadsheet with gauges, nodes and colors on it. It might be helpful to you if they used the same color schema on Kaiser and Frazer cars. They likely did. See the values listed for the HJ and compare to your diagram. If the Tracer column is blank, that means there isn't one otherwise it's listed. Also be sure to follow the gauge listing on your diagram because even on the HJ, the cars with Delco vrs Autolite use different gauges. Example, the white wire from the starter button to the solenoid on an Autolite equipped car is 16 gauge but on a Delco equipped car it's 12 gauge. If a 16 is used where it should be a 12 it will likely not work well and could melt. Good luck!
