I have a '65 C body that I am going to switch over to a 1 wire setup. Off of the voltage regulator, I know one wire goes to field and the other goes into the bulk head. I know right off the bat that the field side can be eliminated because I won't need it. Can I just clip the wire going into the bulkhead and be done with it?

The wiring has been hacked and I am eliminating anything that will not be needed.
