    Description

    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.

    This is for the crazy dash indicator light system that some mad scientist at Ford designed. The system is genius...but hard to troubleshoot. My system has the 1157 plasma LED rear, 1157A LED front, the factory and the Cougars Unlimited solid state sequencer. I also have the LED dash lights.

    With this setup the load across the K7 relay coil drops from factory of 8-10A to less than 2A. 2A is not enough to pull in the K7 coil...so your turn signal lights in the dash will not cycle with the factory K7 relay. My dash lights stayed on all the time! The solid state relay fixed this right out of the box. Mount it, plug it in, and it works. I love it when a part does what it should...right out of the box.

    As with all things Cougar under the dash, it was crowded to install, but fits perfectly and works great. It's nice to have properly blinking dash turn signal indicators.

    I had no flashers flashing on the dash, research lead me to buy the K7 relay. I had to move another relay to attach this one because it is about 1/4 inch wider than the original, but was not too much of a problem. Kind of tight area to work in, that is all. Once I got it installed, my flashers in the dash were working, with sound too. Even though they were working on the outside before I installed the new one, it would have drove me crazy not working on the inside. Great product
