I believe I have figured out that the Lite Blu and Brown (or Orange) wires are redundantly redundant....with the MSD and Pertronix perhaps. In stock config, orange (or brown) wire is +12V at "start/crank" from "I" terminal on starter solenoid to +coil....and Lite Blu is Resistance wire from switch...for "run".
I know that one red is +12V "Run" to MSD. (top in pic)
Second red with shiny crimp goes to +side of Pertronix unit in dist.
Guessing that third of my Red wires is main +12V from the ignition switch during "RUN".
With +12V going to both Pertronix and MSD, then the resistance wire, as wired, is unneeded?
(Depends on if in the IGN switch if RUN and START are connected together during start.)
Also, I don't know if the "Start" wire (Orange) is needed any longer to bypass (the resistance wire) or provide full +12V during start.
Both the resistance wire (lite blue) and the bypass (orange) wire circuits would be in parallel during crank or "start".
Gonna go stare at SOBill's drawings some more as well as the MSD tech sheets.
Worse case, when I get this all put back together, I disconnect these wires and see what happens! If nothing happens...better plug them back in! If noting still happens....hmmm, left something unplugged!!!!
Some really great ideas for junction blocks etc here!!!!
The good news, is that I have now identified cut wires and "hangers out" wires for the most part!!!
OK, time to get back to busy!
Thanks all!!
