Question type: Maintenance & Repair

tdi engine was removed about 1 year ago and a used one was going to be
install but things came up and now i'm fuzzy on the function of this 3rd wire
with a regular terminal that would go over the stud where the battery wire is
on the solenoid but i feel this could be a heavy ground wire , testing with
ohm meter and test light did not prove anything .  i' m a ford master tech
