Supplemental Braking System for Towed Vehicle Travelling Steep Hills
Question:
Thank you so much! I was leaning to the SMI Duo. I'm going with the Roadmaster Falcon 2 AT and base plate and have the wiring kit, smart diode kit and battery disconnect on the way as well. We'll be hooking to a 7-pin on a Newmar Ventana LE. The toad is 2019 Ford Edge ST. Are there other parts in addition to the Duo I'll need? I believe it already has a battery charging line. Maybe a brake light switch? I don't know, please advise.

For an application where steeper inclines will be traveled on the Invisi-Brake # RM-8700 would not be my first choice for a supplemental braking system since the braking pressure when you apply the tow vehicle's brakes will always be the same pressure. Instead I'd recommend the DUO part # SM99251 which is a similar type of system but uses an inertia sensor to detect how hard you are applying the tow vehicle brakes and applies a proportionate amount of braking to the towed vehicle's brakes. The install is overall easier than the Invisi-Brake too.
The second line splice you mentioned in the video of this on the 2015 model would be the same on your 2019 model as well. I attached linked to the install video for you to check out too.
