How to wire a push button starter
Installing a push button starter transforms your ignition. (luxury car - model toy car image by alma_sacra from

In today's world, convenience is a major consideration in the design of nearly every new product and service out there. This dedication to convenience is the same type of thinking that is behind the automobile industry's push button starter concept. This keyless alternative allows drivers to start their car without ever having to insert a key again. Instead, all you do is push down the break pedal and press the start button, and the vehicle is ready to go. Even if your vehicle is not equipped with this technology, you can install one yourself and begin to enjoy the convenience of a keyless ignition.

  1. 1

    Remove the dash around the steering wheel, including the housing for the steering column. Use a Phillips screwdriver to remove the screws that hold the dash securely in place. Refer to the owner's manual of your vehicle for brand-specific dash removal instructions. Also remove the cigarette lighter and all of the surrounding pieces.

  2. 2

    Apply a thin layer of super glue to the chrome ring on the back side of the push button.

  3. 3

    Insert the push button inside of its housing into the hole where the cigarette lighter was once located. Apply pressure to the outside of the push button for approximately one minute.

  4. 4

    Wire the key harness, which is the piece that is running into the key switch assembly. This harness goes under the steering wheel and down the left side of the steering column below the key hole.

  5. 5

    Remove the harness on the back side of the key switch, and cut the 12 awg starting wire on the harness. This is a black wire with a blue stripe.

  6. 6

    Tape the end of the starting wire that runs to the key switch. Connect a 36-inch piece of 12 awg wire to the other end of the same black and blue starter wire with a shielded butt connector.

  7. 7

    Tap the black wire with the green stripe with a 36-inch-long piece of 12 awg wire and wire tap, making sure to avoid cutting the wire. Reattach the harness to the key switch.

  8. 8

    Connect the loose end of the 36-inch piece of 12 awg wire (the wire you tapped into the black wire with the green stripe in the previous step) to the harness using a butt connector.

  9. 9

    Touch the ground cable to the battery terminal without tightening the connection. Insert the key in the ignition and turn the engine on. If the engine does not start, check the battery connections.

  10. 10

    Reinstall the dash board by returning the dash cover to its original position and tightening the screws with a screwdriver.
