Thank you. I am aware of the steps. The last post gets more to the root of my question. Want to tow with an Air Force One brake system that requires power. Therefore I have to disconnect the batteries but get power to the AF One and the lights. Looking for help on the steps to do that or to put the installer in touch with. We have been pulling a Jeep Eco Diesel which is a piece of cake. I can’t drive the dam thing. We decided to tow pickup and wife hates my Super Duty and the fact I ordered a new one. To keep the peace we went back to GMC (we have had a bunch of them). I like it OK but wondering if got myself in a can of worms towing this thing.
