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 your original mechanical relay will be C8WB-13A366-A or C8WB-13A366-C, the Ford part number this unit replaces is C8WY-13A366-A or C8WY-13A366-C.

This is referred to as the "K5" relay in the Ford service manual. This relay causes the flashing action of the 1968 Mercury Cougar instrument panel indicator lights.
*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.
