    Theres a box to the right and up from your park break pedal. It has a fuse emblem on it I believe. That is really the easiest/only place i could find switched power accessible inside the cab. I believe that's where the Integrated Trailer Brake Controller would plug in at.. but there are sever open slots. best way to find out which prong you can use (FYI i used a FEMALE QUICK CONNECT terminal and cut half of it off and slid it onto the prong.. it has worked great for the switched power for my amplifier) is to connect your ground and add this terminal to the pos wire and trial/error the piss out of it. when you find one that is OFF when the ignition is off stick it there and turn the key on. DUH lol. I belive mine is on the left column of open plug-ins and its either the second of third plug-in from the BOTTOM. I hope this helps.

    Side note- IDK how many amps that thing is gonna pull, but you may consider wiring in a relay and just use the plug-in i described earlier to switch the relay power on/off.

    Should be fine then I'd say. Idk if the w/t models have that box setup the same.. but I cant think of any reason they wouldn't. Let me know how it turns out for you. I searched for nearly four hours before finding all that out haha.
