Used under dash wiring harness repair plug and pigtail for the neutral safety switch / back-up lights and engine feed harness for the LATE 1967 Mercury Cougar. Works for both standard and XR7. This is part of the 14401 main under dash wiring harness.
*NOTE* The blue/red to yellow/black wire is for the radio feed. The only difference between the early and late harnesses, is the early harness has an extra blue wire.
