Why Doesn't the Stoplight Circuit Used for Install of SMI Stay-IN-Play DUO Come from Trailer Wiring
Question:
I had a question about product SM99251. I am wanting to install on my ford excursion, and was wondering if there is an alternate way for the detection of a brake signal? I dont like the idea of having to use a light detector rather than having a hard wire into the trailer braking electrical wire from the motorhome. Thanks!

Expert Reply:
The reason you can't use the stop light circuit of the trailer wiring on your motorhome is because that circuit also carries the blinker signal. You have to find a dedicated stoplight circuit and that is why the install instructions recommend you find that under the hood of the towed vehicle.
I attached an install video that shows this getting installed in a similar Ford SUV as yours.
