This solid state turn signal sequential kit eliminates all the mechanical motor-driven sequencers and relays used in the trunks of the 1967 – 1968 Cougars. One system module replaces all these parts found in the Cougar trunk: Sequential flasher and motor (the noisy one), directional relay (the big one), emergency relay (5 pin), and the stop lamp relay (for early 1967 Cougars only). It plugs into the original wiring harness and mounts in the original location without any modifications! These units never fail as they are solid state. We have sold hundreds of them with no problems. Comes with three year warranty. Note: If you are unsure whether your Cougar is a late (after 1/2/67) or early (before 1/3/67) model then order this early unit as it works on both.
