I can send you a photo of where it is mounted and explain how to hook it up, but I don't have mine hooked up. If you hook it up like Shelby did ALL of the power for the car flows through the ammeter in a circuit that is not protected by a fuse or circuit breaker. If the ammeter or the ammeter wiring was to short out the wiring would probably burst into flames just before it melted in two. Not a very appealing thought. I'm going to add a fusible link to the circuit. Not "factory" but a lot less dangerous. Email me at [email protected] and I'll send you a photo.
