Hi I have a 02 ford 350 class C RV. The RV comes with a 6way harness, and has no brake controller. The 26 trailer Im pulling has a 7way harness. Im going to but a brake controller on. How do I find the brake control wire in the truck that goes to the trailer harness on the back of the RV. If I there is a wire going from the dashboard to the trailer harness, that would controll the trailer brakes. Will part #47435 work. Is there anything else I need. Thank you
