I found out by trial and error. I tried to wire the Equinox the same way I did our old Saturn Vue, and it didn't work. It was very frustrating because I kept getting different results. That was because sometimes it was less than 10 minutes, and I was getting voltage on certain wires; but later, lights wouldn't work because I had closed the door and 10 minutes had passed.
Some auxiliary toad brake systems need a signal from the toad's brake light switch in order to operate the monitor in the motorhome that indicates the toad brakes are being applied. Fortunately, ours doesn't; but if yours does, you will need to install a second brake light switch
in the Equinox to provide this signal because of the fact the Equinox brake lights shut down after 10 minutes.
