    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.

    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.
