Review: It's working as a plow relay. and so far so good. - So far so good.. I'm using this as a plow relay. I have tried 4 or 5 smaller 150amp models and their quality was for naught. So I decided to go this way. Wiring is a little more complex as there are 4 contacts wire positions.. they are basically NO.. When you energize one circuit this closes one set of contacts. When you energize the other set of contacts the first set opens and the second set closes. Not what I expected so only use 1 set of contacts since I would need to have 2 switches to use both sets of contacts. So is it 500amps.. Probably 250 per set of contacts.. So far it's still working unlike the other units I tried. I am 10 snow storms in.
Review: Great as replacement for motorhome hydraulic jack pumps. - My motorhome jack relay went out for the second time. The dealer wanted over $200 for the part, which is susceptible to water. This relay works great and is less than a quarter of the price.

## Features

- Solenoids are electromagnetic switches. The winch solenoid is used to activate the winch motor on a vehicle-mounted winch. It is designed to supply the required current without damaging the winch motor or the winch switch.
- It is activated when current from the battery is directed to the solenoid by pressing the switch of activation. The activation of the winch solenoid sends current to the motor. Then the winch motor begins to run the winch drum. The typical winch uses separate winch solenoids for reverse and forward. Best quality winches use four winch solenoids.
- This solenoid relay could be applicable for Winch Motors, Snow Plow & Spreader Motors, Windlasses, Hydraulic Pump Motors & Other Reversible Motors, etc. Heavy Duty Waterproof Solenoid For 12V up to 17,000lb.Voltage:12V, Power: 500 AMP, Dimension:3.9x2.3x3.1 inch/ approx. 77 x 36.3 x 86.2mm (L*W*H).

### ⭐⭐⭐⭐⭐ Excellent
*by R***R on February 15, 2021*

Great all-in-one unit. I wanted to replace the dual solenoids and the massive box they’re housed in that came with the X-Bull winch. This is small enough to mount inside my bumper next to the winch and still have room for fog lights in front of it (1st Gen Tacoma). The wiring for the X-Bull is different than the diagram that comes with the unit. Some quick poking around with a multimeter and comparing the results to the stock solenoids quickly revealed the proper setup. I have it wired to both an in-cab switch, wireless receiver, and to the wired control. So far, so good. I got this one because it came with boots. They’re extremely tight but they’re on.
