    Description

    *NOTE* According to Phil Parcels of the National Cougar Data Base Project, the approximate cut off VIN for determining EARLY or LATE 67 is: 7F91C547891

    Cars with a VIN number higher than this would use the late sequential unit. Cars with a VIN number lower than this would use the early sequential unit.


    This solid state turn signal sequential kit eliminates all the mechanical motor-driven sequencers and relays used in the trunks of the 1967 Cougars built after 1-2-67. One system module replaces all these parts found in the Cougar trunk: Sequential flasher and motor (the noisy one), directional relay (the big one) and the emergency relay (5 pin). It plugs into the original wiring harness and mounts in the original location on the original rubber board without any modifications! These units never fail as they are solid state. We have sold hundreds of them with no problems. Comes with a three year warranty. 

    Replaces Ford Part # C7WY-13A366-B

    Asked:
    I have Sequential unit # 26708, + a bunch of different plasma LED bulbs. Do I need pt. # 31291, specifically the module pictured?

    Answer
    The flasher upgrade is recommended, some cars need the flasher upgrade, some cars work fine without the upgrade.

    Question
    Asked:
    Are these units compatible with the LED and "plasma" lamps?
    December 6, 2020 1:07 PM
    Answer
    WCCC Admin Answered:
    The 67 and 68 can use the same sequential unit for LED / Plasma / Convention bulbs, although it is recommended that you do not mix them. If you are upgrading to LED/Plasma bulbs it is also recommend that you upgrade to the solid state sequentail unit if you have not already done so.
