Standard: 50 watt resistor and two, high-quality t-taps. One per lamp required.
Plug-n-Play: Connects to the fascia harness at each side of the trunk. Sold as set of two.
Note that the '10-12 cars need a ground connected, or, tapped on the driver side. Also, the connector change happened some time in 2012, so, please check your harnesses to see if you need 8 or 12-way plugs. We now know that VIN C9178649 and up have are the new version. If you have a lower VIN and have 12-way connectors, plaase let us know!
If you had these on a '10 through early '12, and, upgraded to a newer car, you want the upgrade version.
