I purchased a toad with an Invisibrake system and have some questions as I have never used this system before. I purchased the warning light that mounts in the motorhome, all other components appear to be in the tow vehicle. My question is, once I connect the warning light and run the wiring from front to back in the motorhome, is there anything else that I need to do or need to purchase to make this connection and ensure that everything works properly? Please let me what I need to know and thanks.
