    Description

    Please Note:

    Many used items in our pictures have been cleaned and/or bead blasted prior to being photographed to show condition and detail. 

    The item you receive, in most circumstances, will be pulled from the donor car and shipped to you without being cleaned. 

    We do not retake pictures each time a used item sells. Pictures are a good indicator of what you will receive, but not all used parts age the same. On high dollar parts, email us and we can send a few pictures of the actual part available.

    "Core" Items:
     If we use the word "Core" in the title of the product, the item has been deemed rebuildable, but has not been rebuilt.  The item you receive, in most circumstances, will be pulled from the donor car and shipped to you without being cleaned.

    Used late grade "B" under dash wire harnesses. There are two versions of this harness, and early and a late version. This late version is for Cougars built after to 1/3/1967, the early version is for Cats built prior to. 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.

    *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.

    Pros:
    Cons:
    Overall the harness is perfectly usable. The connectors were correct for the year and the harness was fairly clean and in good shape for the age with no dried up wires or breaks in the insulation. However, when I opened the box, one of the splices had come apart in shipping. I tested the rest of the splices that I could see and a few more came loose in my hand with very minimal pressure. I could imagine them easily coming loose while tugging and moving the harness while installing it in a car, so I removed the new electrical tape that had been applied to the harness and found a much larger number of splices. The description of the product said "one or two repairs" but it seems there were many more than this, more like 5 repairs comprising a number of splices each. Not a big deal for the most part, but a number of the splices that were under by the electrical tape were also loose and had to be repaired. I would suggest to WCCC that each splice be soldered instead of using crimps on future versions of this to ensure no intermittent circuits happen. I still think it's a decent deal if you need a harness but don't mind that it's made from pieces , but I now think the price was a bit high for the amount of work I needed to do on it.
