So I was wiring up a heater with a relay and circut breaker for my vegetable oil kit and I attempted to ground the relay to a post on a little black box that is mounted on the fire wall of my truck and I cranked it down too tight and broke it. Its a little black box about one inch by one inch that is held on by two small bolts and has two small posts coming out of it. It is on the fire wall directly behind the brake cylinder and about two inches below the hood line. It has a couple black wires going to it and a larger orange one. Anyone have any specifics on what this is/does? Thanks
