How to Wire an F150 Overdrive Switch

An overdrive switch allows you to control your Ford F-150's transmission through the use of a switch. When installed, an overdrive switch can greatly cut down on the fuel usage of your truck. If you have already installed your overdrive switch, you can wire it to your F-150 through the electrical wiring components of your vehicle's steering column using a wire tap connector. As the steering column already contains the proper wiring, you can remove the cover to access the components and wire them to the switch.

Instructions

1

Open the F-150's hood. With a socket wrench, disconnect the battery's negative terminal. Wait a few minutes so that the airbags can deflate.

2

Remove the screws from the rear of the steering wheel using a Phillips screwdriver. Pry off the steering wheel cover with a flat-head screwdriver. Disconnect the airbag's electrical connector and remove the airbag.

3

Remove the screws from both the upper and lower steering column covers. Use a flat-head screwdriver to pry off both of the covers.

4

Disconnect the electrical wire connector of the ignition switch and place a wire tap connector onto it. Reconnect the ignition switch and overdrive switch to the connector.

5

Reattach the covers and their screws. Reattach the airbag and the steering wheel cover. Reconnect the battery and close the F-150's hood.
