I believe the wires were to a heater strip to keep the mech from freezing up in the cold, the mech should be mechanical no power required.
Brian is correct. Some of these machines had a small ceramic heater strip in the coin rejector that was designed to keep everything from freezing on machines that were in outdoor locations. That should not be a necessary part on a machine that will be used in the home or garage. If the strip is still there, it should be visible on the front of the rejector about half way down. I would just remove that entirely.
I am getting ready to start a 110 restoration with my son so I will be watching for your pictures!
