    Description

    NOS sequential unit for the taillights of the Mercury Cougar

    Ford part # D1WY-13A366-A.

    1971 Cougars built from 2/1/71 to 5/15/71 used a unique sequential system in the trunk, D1WY-13A366-C. It uses two connectors, grey and light blue, that are no longer serviced. When the sequential system must be serviced, it can be replaced by an NOS unit, or a replacement unit, such as the C9WY-13A366-AL sequencer shown below. Since these unique connectors are no longer available, the connector plugs on the tail light harness must be replaced with the more typical red and black plugs. The C9WY-13H366-AR harness connector repair kit provides these plugs along with about 12” of wire for splicing. Installation requires cutting off the old grey connectors and splicing on the new red/black connectors while matching up the wire color codes. Slide heat shrink tubing over each wire and solder (no butt splices) each connection. Wrap the bundle with electrical tape to protect the connections. Remove the old sequential system board from the black case, install a new C9WY-13A366-AL sequential system board and plug into the harness. Replace the turn signal flasher can with a D0WY-13A366-AR when using 1157 bulbs or a D0WY-13A366-L flasher when using LED bulbs. Remember to test both the turn signals and brake lights prior to driving the car.
