Painless Wiring Dual Activation Electric Fan Relay Kit

The Painless Wiring Dual Activation Electric Fan Relay Kit line delivers a complete, ready-to-install electric cooling fan control solution engineered for hot rods, street rods, muscle cars, and custom builds — particularly those equipped with or being upgraded to air conditioning. Built by one of the most trusted names in performance wiring, this kit series eliminates the complexity of custom fan wiring with intelligent, automatic dual-trigger operation straight out of the box.

How It Works

Every kit in this line is engineered around dual activation logic — your electric cooling fan engages automatically under either of two conditions: when engine coolant temperature reaches the thermostatic switch's preset threshold, or the instant your A/C system is switched on. This two-stage approach protects your engine from heat soak while ensuring your A/C condenser receives consistent airflow at all times, regardless of vehicle speed or driving conditions.

Key Features:

• Dual activation design triggers fan operation via a thermostatic temperature switch or A/C compressor engagement signal
• High-amperage relay(s) with mounting base(s) provide robust, reliable circuit switching for demanding electric fan loads
• Pre-terminated and printed wire harness enables fast, clean, and error-free installation
• Thermostatic switch with NPT adapter fitting(s) included for a fully self-contained cooling control solution
• Circuit protection via circuit breaker or fuse guards the electric fan circuit against overload
• Posi-Tap connectors (on applicable variants) simplify ignition and A/C signal tap-ins without cutting factory wiring
• Thermostatic switch compatible with cylinder head, intake manifold, or radiator housing mounting locations
• Mounting hardware, insulated terminals, and illustrated instruction sheet included for confident DIY installation

Available in multiple configurations to suit single-fan and dual-fan setups — including variants with platform-specific connectors for GM builds — the Painless Wiring Dual Activation Electric Fan Relay Kit line offers a professional-grade cooling control solution for virtually any electric fan application. Select the variant that best matches your fan configuration and desired activation temperature for a clean, reliable result with minimal wiring complexity.
