When installing a push-button ignition switch, start by attaching a memory saver device to the vehicle's 12-volt outlet. Remove the negative cable from the battery before plotting the switch's location. When determining the ignition switch's placement, ensure that it is in an area where the driver of the vehicle can easily and safely reach. Check the switch's size before drilling to select the appropriate drill bit needed for the job, and then drill a hole into the dashboard.

Take 1/4 inch of the insulation from a 14-gauge wire and crimp a solderless terminal to it. Secure it to the back of the switch and find the starter solenoid in the vehicle's inner fender. Run the wire from the switch into the solenoid. Strip a longer wire in a similar manner and attach it to both the switch and the positive terminal of the battery.

Mount a fuse under the hood with zip ties or sheetmetal screws. Bring the power wire to the fuse and strip its ends. Attach them to the wires located on the fuse holder and install the fuse. Contain any excess wire with zip ties and push the ignition switch through the dashboard hole. Mount it in place by applying the trim bezel. Connect the battery to test its operation.
