You should install this instead of just a tap the wires.

Thinking about all the electronics in today's vehicles I did some checking. The electronic box (CURT T-Connector) controls the trailer lights separate from the vehicle's electronic electrical system. It only gets a signal to control the box that controls the trailer lights. What this means, something goes wrong with the trailer lights it does not effect the vehicle lights or electrical system. The install was plug and play, except for hot wire routing. Worth the cost & time!
