1 Pack Waterproof Relay with Harness, 5-Pin SPDT 12V 40/30 AMP, Heavy Duty 12 AWG Tinned Copper Wires, Automotive Marine Relays Universal for Boat, Truck, Van, Motorcycle

【Security & Protection】: Relays play a role in circuits for automatic regulation, safety protection, switching circuits, etc. Considered the electric shock when using under large amperage, this dc 12v relay adopts higher voltage limitation of trigger switch to enhance the life cycle and safety when using. 【Reliable Materials】: The shell is made of high temperature flame retardant ABS. 12AWG pure oxygen-free copper is used as conductor to ensure its good conductivity. The bottom part adopts waterproof sealing technology and the back part adopts fixed back strip, which is suitable for various complicated installation environments. 【Specifications】: 12VDC (14V Max) 5-pin SPDT (single pole double throw) relay with 40A/30A high switching capability. Wire specifications: White - Ground (85), Blue - VDC (30), Black - Trigger (86), Red - Output N/C (87a), and Yellow - Output N/O (87). 【Pigtail Included】: Easier to remove, more secure and better looking than the usual mess of wires and terminals. The included pigtails and sockets clean up your wiring, shorten repair times and simplify fault diagnosis. 【Universal】: The universal 5-pin relays can be used as a single, normally open or normally closed relay or in more complex setups like a custom power lock and window build.
