Specs At A Glance

Good To Know

Q: Will this solenoid work on a standard 2-plug Western plow harness? A: Yes, it is designed as a drop-in replacement for the original relay in most Western and Fisher harnesses, but always verify the connector style and mounting bracket before installing.

Q: Can I test this solenoid before mounting it on the plow? A: Apply 12V to the small coil terminals and listen for a distinct click, then confirm continuity across the heavy-duty terminals to verify the internal switch closes properly.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
