1971 Slant-six ballast resistor ID
If you want to figure out what each blue wire connects to, without unwraping the harness tape, make continuity checks on each one.
In other words remove them from the resistor and each other. Then check each for connection to the alternator field, regulator, and any smog era devices such as choke assist if they are present.
My guess is that one wire is the J2 from the key switch Ignition Run. It should have a white tracer on it according to the book.
And the other leads to a splice or a junction at one of the other terminals.
