Interlock device installed in your vehicle

Hi - I am Dave, contributing to RepairPal and providing expert advice since 2010. What type of Interlock device - like an alcohol one? If it's that, you'll need to seek guidance from the folks that installed it. If it's a factory equipped interlock - like for the shift lever release with the brake pedal - parasitic draws are often found by eliminating the affected circuits by removing fuses to see when the draw stops.
