Tested and inspected neutral safety switch for the C-4 transmission installed in early 1967 Mercury Cougar and Ford Mustangs. Found on cars before build date 12/15/1966. This neutral safety switch is identified by having two plugs that plug into the single 4 pin plug, coming from the firewall. The later neutral safety switch with a single 4 pin plug will also work fine.
Look for a transmission code of W on your door data plate. If your car has a code U, your original transmission was an C-6 and uses a different neutral safety switch.
