This dual-activation relay kit is designed for vehicles running electric dual cooling fans, especially those equipped with air conditioning. The system automatically turns the fans on at the preset temperature using the included thermostatic switch, and also activates them whenever the A/C is switched on. It provides clean wiring, reliable fan control, and protects the vehicle’s electrical system with proper relays and fused circuits.

Kit Includes:
• Three 40-amp relays with mounting bases
• One 70-amp fuse with holder
• Pre-terminated, printed wire harness
• Thermostatic switch: 185°F on / 175°F off (3/8"-18 NPT thread)
• 1/2" NPT to 3/8" NPT adapter
• Mounting hardware and insulated terminals
• Detailed instruction sheet

Ideal for dual-fan cooling setups that need automatic temperature-based control plus activation through the A/C system.
