I have a 1989 Newell and need to install a brake controller in the coach.
I have never pulled a trailer with this coach but will be doing so on my next trip.
 
This coach has a 7 post terminal (round male) at the rear of the coach but does not have power to this unit as near as I can tell.
I will need to change the rear terminal to the flat blade spade type.

My immediate problem is to locate the wiring which I presume will be under the dash.

Any input will be appreciated.
