2011 Jeep Grand Cherokke Overland

Thinking of getting a new GC Overland but heard that you have to
disconnect the negative battery cable. I need power for my brake
buddy. Anyone know if the battery cable has to been disconnected?

Can't answer your question directly, but can tell you what I did on our '07 Wrangler. I rewired one of the dash 12v recepticles so it is powered through the tow harness (same as used for the tail/turn/stop lights) and installed a blade switch on the negative battery terminal. The brake is now powered from the motor home.

I don't disconnect mine. I have the US Gear Unified Brake System. It's just plug and go. Call Jeep customer service. I was told that under normal use---a day's tow--and the driving the Jeep, ya don't have to worry about it.
