This is the missing part. Very easy to install. I opted to install on driver's side with headlamp controls. This makes it easy to open without climbing in car. Just remember, it will open the trunk with the car in gear, you are bypassing the lockout that the key fob uses.
Great product - easy to follow instructions and OEM install. It only takes a few minutes to install.
This is one upgrade that everyone should do. It looks just like it was there from the factory. It's easy to install.
