Hey Justin, like all brake controllers the Redarc Tow Pro Elite part # RED44FR does stay "on" all the time but it will go into a sleep mode after a few minutes where it shouldn't draw hardly any power. Certainly not enough to drain a battery overnight.
Did you try and start the vehicle after the install? Typically in this situation it's the dome light being on during the install process that drains the battery and the next time you attempt to start the vehicle the battery is dead. In your case that could end up being the next day. Let me know either way and lets figure this out.

Hey Justin, what ended up happening after you tried starting the Suburban again with the Redarc Tow Pro Elite installed? Knowing if the battery held up could help others who notice the controller light staying on. Your update could make it easier for the next person with the same concern.
