We chose a single electric fan because it was thinner than the dual unit. This extra space was required because of our supercharger's serpentine beltdrive. The single unit also allowed us to move it around on the radiator to gain the most clearance. The fan comes with its own mounting straps, but we had to dig into our own stash of nuts and bolts for fasteners. We already have a few other items running to the solenoid, so the unit was wired to a switched lead in the fuse box. The ground wire was mounted to another ground on the inner fender. We ran the wires along the bottom core support to conceal them.
