Abstract:
1. A device for interfacing between a battery/OEM electrical system of a vehicle and the vehicle's aftermarket accessories, comprising: a remote isolator interface and a magnetic battery disconnect, where the remote isolator interface additionally comprises a ground wire and is electronically connect to a wiring tie in to an OEM vehicle door lock system, and where, when the OEM vehicle door lock system is turned off by a user of the invention, a polarity reversing signal from the OEM vehicle door lock system is created, which reaches the remote isolator interface, and where the remote isolator interface then creates an electrical signal to the magnetic battery disconnect, where the electrical signal causes the magnetic battery disconnect to sever any electrical connections between the vehicle's battery/OEM electrical system and the vehicle's aftermarket electrical systems, thereby preventing, when the vehicle is turned off, a spike and a short in the aftermarket electrical system from affecting the vehicle's battery/OEM electrical system, and preventing a drain on the battery from the aftermarket electrical systems.
