Used plug and wiring pigtail for the brake light warning switch located on the drum or disc brake distribution block mounted to the driver side fender apron. This is a plug and section of wire for repairing the underhood harness.
Works on late 1970 - 1973 Cougars and Mustangs. The only difference between the late and early pigtail is that the late plug is white and the early plug is black. No difference in wiring.
