Things You'll Need
Instructions
Locate the audio/video hookups in your vehicle. Check the owner's manual, or ask your auto dealer if you need help finding them.
Purchase a 12-volt power adapter. It has a cigarette lighter connection on one end, and a standard electrical outlet on the other. You can purchase one online or at an electronics store.
Plug the adapter's 12V connector into the cigarette lighter adapter of your car; then plug the Wii's power cord into the outlet end of the adapter.
Insert the A/V cables from the Wii in the A/V jacks in your car.
Position the Wii's sensor bar under or over the TV screen. Power on the Wii by hitting the "Power" button on the console or remote.
