## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great
*by K***Y on March 10, 2024*

Easy to install

### ⭐⭐⭐⭐⭐ Montana 2740
*by B***N on June 26, 2023*

Swapped this out with the ignition switch and the fuel cut off relay at the same time. They lasted 17 years so I think I got my money's worth from the components. I also swapped out the battery as it was dead. Vendor is top shelf and sent out next business day.

### ⭐⭐⭐⭐⭐ Fixed my electrical problem
*by R***. on September 13, 2019*

Prompt shipping and perfect fit for my 15 yr old Farmtrac tractor. Lights and gauges are working again.
