Overview

When a Western plow motor relay fails mid-storm, the 56131K replacement gets the blade moving again without a dealership visit or a long wait on OEM parts. This solenoid is purpose-built to replace Western part numbers 56131K, 56131K-1, 25634, and 56131 — the motor relay used across Western's Unimount and UltraMount quick-attach plow systems. The normally open, automatic-operation configuration mirrors the factory setup exactly, so you're swapping like-for-like without touching the harness or consulting an electrician.

The installation is accessible to anyone who does their own plow service: remove the failed solenoid, transfer your connections to the replacement, and you're back in the seat. The relay is rated for the high-current, cold-weather duty cycle that plow motor control demands — repeated switching loads at temperatures well below freezing. As with any solenoid in this service environment, keeping the mounting area clear of packed road salt and ensuring terminal connections are tight and corrosion-free will get the most out of the part season over season.

Frequently Asked Questions

This relay is confirmed to fit Western Unimount and UltraMount plow systems. If you're unsure of your plow type, check the mounting frame or the original solenoid housing — Unimount and UltraMount are Western's two primary quick-attach platforms.
It directly replaces Western OEM numbers 56131K, 56131K-1, 25634, and 56131 — the full range of Western motor relay solenoids used across these platforms, so cross-referencing your existing part number against that list will confirm compatibility.
The relay operates in normally open (NO) mode with automatic operation, which matches the OEM Western factory configuration. No wiring modification or relay base swap is required.
Replacing a plow motor relay is straightforward — a basic socket set to remove the solenoid mounting hardware and a terminal screwdriver for the spade or stud connections is typically all that's needed. The direct OEM fit means no bracket fabrication or wire splicing.
The relay is designed for winter plow service, which means repeated high-current motor switching in sub-freezing conditions. As with any solenoid in this application, keeping the terminals clean and protected from road salt will extend service life.
