This invention is a way to disable a electrical circuit in a mobile vehicle or equipment. This invention works in conjunction with our previous Patent, EMERGENCY SHUTOFF SYSTEM FOR POWER MACHINERY, WIRELESS MONITORING SYSTEMS, AND EMERGENCY SHUTOFF METHODS. U.S. Pat. No. 7,012,519. This system allows a new vehicle or equipment to have a remote controller of the ignition circuit installed, without cutting or damaging the wire harness. This system will not void the manufacture warranty of engine module or computer system. This system will shorten the time required to install our “FOX-PAWS” shut down switch, thus saving the customer time and money.
