First off, welcome to iRV2!
Second, you should add a "signature" to your profile. It contains whatever info you want; most people put info about their coach there, so they don't have to type it into each message. Instructions for adding a signature are here
Re: Trailer electric brake wiring. Your coach is pre-wired.
If your coach is built on a 2008 chassis, there's a six-pin connector under the dash to the left of the steering column. See the 2008 Ford Body Builder Layout Book, pages 345 through 348 (link here
If your coach is built on a 2009 chassis, there's a connector behind the change cup in the dash. See the 2009 Ford Body Builder Layout Book, pages 358 through 360 (link here
I suggest you do yourself and the next owner a favor by not cutting off the Ford factory connector, or splicing into its wires. Instead, make a plug-and-play installation. etrailer offers a Tekonsha pigtail adapter that fits in the factory-installed connector. If you buy the pigtail you may be able to use it with a different controller, if it uses the same connector and pinouts as the Tekonsha. If not, you can still use the pigtail by cutting off the Tekonsha connector and splicing it to the pigtail that comes with the controller.
For a 2008 chassis: Link to the Tekonsha 3035-P Ford adapter is here
For a 2009 chassis: Link to the Tekonsha 3034-P Ford adapter is here
The Tekonsha P3 is a popular choice for a controller. Link is here
