...actually the 'Original' Factory Headlight Relay IS SPECIAL!! On the '74's it is located behind the cover, down below the drivers' left knee. It controls the Headlight Door opening/closing AND (I believe)the Lights themselves. It has Multiple Contacts inside and Multiple 'Blade' plug-in's to the exterior. You'll need the wiring diagram if your going to change IT over to aftermarket relays, and you will need 2 or 3 relays to replace the One...
