Used early grade "B" under dash wire harnesses. There are two versions of this harness, and early and a late version. This early version is for Cougars built prior to 1/3/1967, the late version is for Cats built after. In January of 1967 Mercury eliminated the stop lamp relay and integrated it into the sequential main turn signal relay, known as the K8-K9 relay. The early and late versions will not interchange with each other. All our harnesses will be inspected, professionally repaired, tested, and ready to install when they arrive at your door. Grade
"B" harnesses may have one or two repairs as where the grade "A" harnesses
will be rare uncut beauties.
*NOTE* 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.
