Yes, this is a common question we've received about the Roadmaster Battery Disconnect with Switch for Towed Vehicle w/ Flat Tow Brake System # RM93MR. Vehicle owner's manuals say to disconnect the negative post while Roadmaster always says to disconnect the positive post. Since this is a Roadmaster product you'll want to install it according to their instructions.

Please note this product is for diesel vehicles and if you're using a braking system that draws power off the battery you need to install the Charge Line Kit # RM-156-25 as well to prevent your battery from being dead.
