Stop light switch kit with SMI Stay-n-play
I've spent time here on RV.net and elsewhere trying to understand the in's and out's of dinghy towing. So here's the question I can't seem to find the answer on: On the SMI Stay-n-Play supplemental ...

There is an LED light strip in the Stay in Play kit that mounts on the dash of the motorhome to indicate when the toad brake pedal has physically moved away from rest position (toad brakes activated). I needed the extra Stop Light Switch kit to operate that LED light.
Our 2014 Equinox does not have a standard brake light switch that I could have used. It has an analog brake position sensor that tells the computer when to activate the brake lights (among other things like ABS etc).
The extra brake light switch is connected one side to a positive, always hot, fused source. The other side I wired to the blue wire in the 7 pin plug that is normally used for trailer brakes. Using the trailer brake pigtail connector under the dash in the motorhome, I wired the LED to the blue wire to indicate when the toad brake pedal moves. That saved me from running a separate wire the length of the motorhome since I don't tow a trailer.
It's a very nice feature that tells you when the toad brakes are working and helps in making sensitivity adjustments.
The brake lights/turn signals on the rear of the toad are operated by the wiring from the motorhome through the cord plugged into the rear of the motorhome. With the Stay in Play, the brake pedal in the toad will not be activated with every stopping condition like stop & go city traffic, it is a supplemental system. Therefore you want an indicator to tell you when the brake pedal is actually moving in the toad.
