I am an f'ing spazz. I have a 2013 Switchback and the manual....and can't find the accessory port. It is mixed in with the wiring under the seat pan? My understanding is that it's a separate and different connection from the data port used to connect something like a tuner located in the left side electrical caddy. Or, are they the same?

 

Maybe these will help?
