How to Install the Monitor Light from the SMI Stay-IN-Play on a 2016 Cadillac SRX

Updated 02/07/2019 | Published 02/06/2019

Question:

I READ ON THE Demco site that there is a problem with trying to tap into a GM Cadillac SRX wiring for the brake light +12 volt wire for the installation of the Stay-In-Play DUO braking system. But you say that braking system is compatible with the Cadillac SRX. So, I dont understand? How do you get 12 v from the brake light wire to the SMI controller????

The SMI Stay-IN-Play DUO Supplemental Braking System part # SM99251 is compatible with your 2016 Cadillac SRX. However, as you mentioned the stop light circuit on this vehicle will go dead while in tow mode. Therefore, in order to power the monitor light you will need to run the red wire from this to the blue wire that goes between the breakaway switch and the operating unit.

I have attached a diagram to help with this as well.
