Under the RHS of the tub liner is the wiring where the loom would plug into, there are two grey connectors that disconnect and the new loom will plug into them, also an earth wire is tapped into the existing earth near the tail light. At one end the cable is connected to the hard lid to control the actuator. Another cable will feed through the center tie down bracket and connect to the strut to control the on/off of the light.
It is very easy to install.
