Installing Power Awning on door side slide-out

Has anyone installed a power awning on the door slide out of a BH 3685, and if so do you have any suggestions for me before ordering . Thank You

I love mine, but did not put in myself. When I ordered my 2014 3685 I added the extra slide out awning. I know the walls on both sides of the windows are prepped for it. They installed the power switch next to the dinette light switch on the wall behind the dinette chair.

Thank you Glen, I have a 2013, I called Heartland and talked to Ron in Service, he is supposed to be sending me a schematic of the door slide out. I am waiting for it to come in so I will be able to place the awning hardware in the right places. I will keep you updated. Thanks Again.Ron
