It's not exactly plug and play. In addition to finding the unterminated wiring under the dash and connecting them for the controller harness, there are two wires under the hood that need to be connected. The terminal studs at the front of the fuse box are metric and you will need to buy metric nuts and the fuses to power them. One stud is for the controller 12V+ feed and the other for the battery (aux) feed to the 7 pin connector. The owners manual should show you the positions and what amp fuses to buy. My TT dealer tried to sell me a $7 fuse that Wal Mart had for $2. Here is a link to an install video.
