This is a good used power wire that passes through the firewall, travels along the passenger side engine compartment and mates the the rectangular power window relay. Fits 1969-70 Mercury Cougars with factory power windows. This is a Grade B harness that has been tested, inspected and repaired as needed. This harness will function properly, but will have some obvious repairs. We also sell a Grade A harness that will look much better for judging.
