Not really. The dealer installed it at the time of purchase.
Seriously, the advantage of living with one fifth wheel for 16 years was that when we began our search for the next one, I new what I wanted to have included at the time of sale.
The manual is available online if you search for the model number and the instructions are pretty clear. On mine, with the In-Command system, the necessary generator wires were tapped right where they run into the BCM control unit.
