    Supplier Backordered, ETA January 2023

    Due to overwhelming demand, WCCC is now able to offer a 1970 Cougar Electric Headlight Door conversion kit. This kit will replace the old, tired, vacuum system that likes to leak and wear out. There are few differences between the 1969 and 1970 conversion kit.

    When you purchase this electric actuator kit you will get a remanufactured 1993 - 1996 Ford Probe motor, a fused wiring loom, and a relay. This kit also includes detailed instructions for easy installation. Simply remove all existing vacuum components and replace them with this kit. When installed properly, you will have headlight covers that work under any conditions with the car running or not.

    If you have a high performance engine with low vacuum, this is a must have kit for your Cougar.

    Actuator Heim joints are fully adjustable to keep your grille and headlight lids nice and straight without slack. Another advantage of this electric system is that it doesn't put constant pressure on your grille like the original vacuum system does.

    These kits have a 3 year full warranty against manufacturer defects.

    We've had questions about what body plug to use at the firewall when getting rid of the vacuum hoses and converting to the electric headlights. You can click on the link in the video, or get the 1 1/4" body plug here.

    Installation instructions:

    1. Unplug headlights

    2. Remove clips on vacuum motor arms to headlight doors.

    3. Remove 2 springs on each headlight door (4 total)

    4. Remove 4 bolts holding the center grill panel to the hood latch support.

    5. Remove 4 bolts holding right and left grill sections to hood latch support.

    6. Remove 2 nuts on back of each grill, located on bottom middle and end of grill (4 nuts


    7. Remove bolt on top of grill under the fender extension pass driver (2 bolts)

    8. Cover bumper, stone guard, carefully remove bolt on top of center of grill, holding on

    to grill, (may require 2 people) do this for passenger and driver sides.

    9. Unplug vacuum hoses from motors, remove 2 nuts holding each vacuum motor (4 nuts,

    bolts total) Remove motors.

    10. Disconnect vacuum hose at intake manifold and install a plug.

    Optional- Remove all vacuum hoses and vacuum reservoir under driver fender.

    11. Motor arms should be lined up in the area painted gray on the motor mount and

    motor arm. DO NOT connect any wires to power at this point, the motor could

    rotate automatically.

    12. Mount electric motor with mount on driver side, using original holes for vacuum

    motor. Push motor completely to rear then tighten nuts.

    13. Mount pass motor mount in original vacuum motor holes, mark 3rd hold and drill a

    5/16 hole, tighten nuts.

    14. Run wire harness to each motor, relay could be mounted on drivers or pass

    fenderwell. DO NOT connect any wires to power yet.

    15. Reinstall grills in reverse order, adjust headlight cover bumpers all the way in, do not

    reuse springs, they are no longer needed.

    16. Ensure the headlight covers are aligned, with the covers closed, check the gray mark

    on the motor arm and the motor mount and align them by rotating the motor knob, THIS

    IS CRITICAL, it is the start, closed position. Measure cover arms, shorten them as

    needed, attach the cover arms with bolts provided, bolts should point toward the center

    of car, tightening them will reduce slack and provide a better adjustment, you may have

    to do this step a few times for adjustment.

    17. Make sure the motors ARE NOT connected to power, then, by hand, rotate the knob

    counter clockwise to open the cover, continue turning counterclockwise

    Do this for both sides. Check for binding. Make adjustments to headlight cover arms as

    needed. Adjust cover arms, motor mount, grill, headlight cover bumper stops can be

    adjusted to ¼ inch from hitting the stops, but not needed …BEFORE POWER IS

    CONNECTED. When covers are closed, the motor arm and mark on motor mount

    should be aligned, failure to align them could burn motors, blow a fuse or damage

    your grill.




    COMPLETELY, check for alignment of gray start position.

    18. Connect wires, red wire to constant positive ie; battery positive or starter solenoid

    positive terminal. Black wire to a good ground.

    19. Simple test. Once the hot wire and ground are connected, you can test the opening

    and closing of the covers by touching the blue(or yellow) signal wire to the positive side

    of your battery. Holding the wire on the positive will open the covers, taking the wire off

    the positive will close them. (IF COMFORTABLE DOING THIS) KEEP HANDS



    20. Connect the signal wire, blue ( or yellow) wire to headlight dimmer switch wire… red

    w/ yellow stripe, wire should come from headlight switch,(67 Cougars with external

    vacuum switch may have a signal wire in engine bay located under windshield washer

    bag red w/ yellow stripe,check this wire for power with headlights on, no power when

    headlights are off ., or use dimmer switch)

    21. Turn the headlights on, covers should open. Ensure they are completely open. If

    they are too tight, the headlight cover arms may need to be adjusted, if they are too tight

    when open, lengthen the cover arm…shorten the cover arm if they are not open fully.

    Some headlight cover sag can be fixed by shortening the arms. Make

    adjustments to motor arms with power wire disconnected!!!

    Motors can rotate automatically and smash your hand!! Use

    headlight cover arms and stops to adjust covers. Motor arms can moved slightly for

    more adjustment but usually not needed.

    • Perfect upgrade
    • Takes time and some effort
    Cat headlights Installation not actually CORRECT but a nice upgrade.

    Removed the old unreliable vacuum headlight door system vacuum actuator can and installed a Cat Headlights electric headlight (HL) door motor. It provides a custom mounted electric motor, connecting rod, wire harness and hardware.

    Cat Headlights instructions are clear and easy to follow. Disconnect the battery, hook the red wire to a power source, and the black wire to ground. The four socket wire connector snaps into the motor connector. A blue wire must be connected to the floor mounted dimmer switch inside the car. Do not make this connection yet. During installation you must manually turn the bottom knob on the electric motor counterclockwise to made sure the HL doors open and close properly. Following the directions, touch the blue wire to the positive side of the battery and watch as the motor cycles to test the installation. Adjust the connecting rod if necessary.

    This single speed motor opens and closes the HL doors quickly. To achieve a slower more controlled motion, Cat Headlights offers an adjustable speed upgrade. I just finished installing their speed adjustable “black box” (BB) and new wire harness, ordered directly from Cat Headlights a few weeks ago. Switched out the wire harness. The new speed adjustable BB was mounted on the right apron below the voltage regulator. First disconnect the kits adjustable rod connecting the motor to the headlight door cam actuator. This allowed the motor to cycle without being connected to the headlight doors. I made sure the rubber stop bumpers on the headlight assembly were securely in place to cushion the open and closed position of the HL doors. Tried the speed adjustments on the BB.

    The lowest BB speed adjustment did not allow the motor to run. Moved the speed knob until almost the mid-point to finally get the motor to cycle. Made a suitable speed adjustment, reconnected the adjustable rod and blue wire to the interior dimmer switch. Everything worked.

    HINT: When trying to pass the blue wire back into the interior of the vehicle found the old vacuum hoses were really hard to remove from the firewall positioned below the left hood hinge especially after 50 years in place. Checked the vacuum diagram and noted the vacuum hose from the carburetor connected to the center of the three hoses on the HL switch. Disconnected this hose on both ends and ran the blue wire through the hose into the interior near the dimmer switch. Made the blue wire to red dimmer switch wire connection leaving the two interior actuator vacuum hoses still attached to the HL switch.

    Have one of only two identical 1970 Competition Orange, Cougar XR7 convertibles. Per the Marti Report they were both ordered in Burbank, Ca. October 24, 1969 with a 351 Cleveland 4V- V8, 4 speed Hurst linkage, PS, PB, 3.50 Traction-Lok, 6Z interior code, and Competition Suspension. This is a solid, no rust California car. Believe the actual mileage is about 120,000. Purchased the vehicle in 1981. Resurrecting it slowly over the past few years. Not sure if the twin survived.
