Will SMI Stay-IN-Play DUO Proportional Braking System # SM99251 Work on 2010 Ford Ranger 4x4
Question:
Does the mercury switch have a single contact or multiple contacts? If it has a single contact, how does it make the braking proportional? Will this system work on a 2010 Ford Ranger 4X4 without additional modifications beyond installing the braking system? Thank you

I spoke with my contact at SMI and the mercury switch on the Stay-IN-Play DUO Supplemental Braking System, # SM99251, actually has one contact and will work with your 2010 Ford Ranger 4x4. You will just follow the basic installation instructions with no additional modifications necessary. I have attached these installation instructions for you.
The DUO is referred to as a progressive system but has the characteristic of a proportional since it uses inertia. This is a dual signal system which activates when your tow vehicle's brake lights go on and an inertia sensor in the towed car detects deceleration. The sensitivity control on the inertia sensor allows you to regulate how aggressively the towed car's brakes activate.
