This is a 2 fan set up designed for an easy clamp on install for any style, any model, any brand, or any size cooling unit coils. The 2 fan set up will come with wiring harness, automatic thermostat to activate the fans when the air temp reaches around the 85 degree or warmer behind the refrigerator when the cooling unit is needing the higher flow of air through the condenser fins. The thermostat is at the end of the wire harness next to the fans and hangs loose not mounted. When you install fans and ready to wire the fans, all that's needed is a 12VDC positive (from any source) and a good DC frame ground (from any source). If you want to connect to the refrigerator DC, the wire harness will come with a piggyback terminal so you do not need to cut any original wires to use fan harness wiring. All wire terminal for hook up are furnished and already crimped to wire harness.
No holes drilled at any time to mount fans or brackets.
