40/30 AMP 12 VDC Relay and Harness. 

Heavy Duty 12 AWG Tinned Copper Wires, 5-PIN SPDT Bosch Style Automotive Relay. We use these relays typically for single color LED installations where the customer wants to simply turn on/off a large number of LEDs at one time.  Offered in two versions:  Standard (no housing) and Waterproof Housing. The standard version should be mounted either inside a waterproof box or in an area that will not be exposed to water. The product photo carousel has photos of both versions.
