## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    Very functional kit but a little difficult to mount
  

*by D***H on Reviewed in the United States 🇺🇸 on April 15, 2018*

I installed this on my tractor that didn't have a fuse buss and I needed to add several circuits. It is well made enough I just wish that the wires coming off the bottom of the fuse holder would have cleared the bottom of the holder. I had to use the accompanying spacer blocks to make enough room for the wires to exit and even then it was still tight. The relay is attached to the fuse holder with a sheet metal screw into plastic and is not very tight. That said it worked perfectly. I used the hot circuit for my battery tender and the 2 switched circuits for a snowblower chute actuator and hydraulic diverter valve for a grapple. I didn't use the main feed circuit breaker as I didn't need the full capacity of the fuse holder and used an inline fuse holder instead. The kit was complete providing everything I needed to hook it up.

### ⭐⭐⭐⭐⭐

### ⭐⭐⭐⭐⭐ 







  
  
    smart way. Plenty of wire to mount it anywhere
  

*by D***E on Reviewed in the United States 🇺🇸 on December 5, 2016*

Does exactly what it's supposed to do: Provide (2) Ignition hot circuits, and (1) constant hot circuit for adding additional electrical components to your vehicle the safe, smart way.  Plenty of wire to mount it anywhere.  High quality wiring, components, and instructions.  Made in the USA.
