    New electronic K7 / 13A366 Turn Signal Relay for the 1967 Mercury Cougar

    At last, there's a solution to a problem that almost all early Cougars suffer from. If the turn signal indicators in your dash only blink once, and then pulsate slowly without going out, you need this new electronic relay. It's a direct plug-and-play replacement, and it will give your indicators a nice on-off flash, complete with a mechanical click sound, all in time with your turn signals. We're excited about this simple fix; it's great to see and hear the indicators working properly.

    The number stamped on the original relay that this replaces is C7WB-13A366-A, the original Ford part number is C7WY-13A366-C.

    Check out this quick before-and-after video demonstration:





    This is referred to as the "K7" relay in the Ford service manual. This relay causes the flashing action of the 1967 Mercury Cougar instrument panel indicator lights.

    Replaced Ford part number C7WY-13A366-C.

    *CAUTION* The 1967 and 1968 K7 relay look similar, but are not the same. Damage to your wiring system will occur with the wrong relay.

    An excellent replacement part. It does fit in the original location and plugs into the original wiring harness without modification. I did have to adjust the mounting tab so that the relay mounted flat in the original location. Its good to get that audible relay click and see that the instrument turn signal lights now turn off and on.

    Pros:
    • Quick and easy installation
    Cons:
    • None

    You have to have this, the blinkers have never worked this good. I will put a blinker on even when I turn around in the drive way.
