Ryan, I HAVE a non cut perfect 1961 Falcon wiring harness in my possession right now...
I'll let you have it for $40 bucks
I thought it was faulty so I swapped it out for another i had but it turned out to be a poorly grounded headlight switch was my problem.
The Pink wire is a resistance wire that will heat up when the car is running because it is naturally reducing the voltage from 12 to about 6 or a little less, to run the Points and coil.
Gotta use a ballast resistor if you do not use that wire.
