Used grade "A" under dash wiring harness with a black plug end for the standard 1969 Mercury Cougar with air condioning. Mercury used either a black or white plug end during the 1969 model year run. If you have a blue printed circuit board, this is the unit you need. All electrical harnesses are inspected, repaired, tested, and ready to install.
*NOTE* Excludes Eliminator - see 1969 XR7. If you send us your old used under dash harness, you will receive an in store credit of up to $100. Also keep in mind that we buy original under dash harnesses. We are interested in all under dash harnesses, but are primarily interested in the XR7 harness.
