    This is the updated sequencer needed for use with the new Plasma LED's and the new updated flashers.

    NOTE: Although your existing emergency flasher might work just fine with the new sequential unit, it is highly recommended that you also use the same updated electronic sequential flasher in its place to guarantee proper operation.

    This is a direct fit replacement, just pop open your black plastic box located in the driver side trunk drop off and plug it in. Your January 1970 and newer Cougar will have external brake light relays taped to the outside of your box, this unit will internalize them with built in solid state units that are silent and much more reliable.

    This unit is located in the trunk behind the driver side wheel house and requires no modification to the original wiring. The two used sequential units shown represent the two versions this new unit was designed to replace. The unit without the external brake light relays was used in 1969 and early 1970. The unit with the four bulky external brake light relays was used from January 1970 to 1973. Note both versions use the same plug configuration. We highly recommend you change the flasher under the dash with our updated unit.

    Dear WCCC, I would like to thank you for having such a great product. It was incredibly simple to install. It has been years and years since the blinkers on my 1973 Cougar have worked properly. Most everyone I talked to about it, didn't want to have anything to do with it. Within the few minutes it took to install your product, I can finally drive my car again without having to worry about a thing. Thanks again!!!!

    I put this unit in my 1970 Shelby along with the flasher and plasma bulbs and all I can say is...WOW! I don't have to worry about other drivers not seeing my directional or brake lights. Very easy to install and I would highly recommend it.

    This unit worked very well and fit without any problem. However, it is difficult to get it to work with LED bulbs because of the issue of finding the correct flasher. Once I sorted that out things were fine. The manufacturer, Mr. Yarberry at Cougars Unlimited, was a tremendous help. His trouble shooting guides were invaluable.
