To ensure every one of my electrical issues were not going to come back and haunt me I replaced the turn signal switch. This was one of the more rewarding jobs I have done on my Cougar, it fixed 2 problems. 1. emergency lights and 2. After engaging the turn signal lever it would never turn off because the cam would never cancel/disengage the lever, I'd be driving around with my turn signal still on this part fixes that. Don't forget to order part # 10686 .Don't get frustrated spend the extra $6.00 and save yourself some time and headache over color coding wires.
