NEW 26400 Isolation Module 4 Port Western Fisher Truck Side Light Harness

These are no longer available from Fisher and Western, we purchased the last of them. When they are gone, that will be it, you will have to convert to 3 port. So get them while you still can. 

A New 4 Port Isolation Module (part # 26400) for Western and Fisher. There is also a different module for certain trucks with DRL lights. These modules rarely go bad, so check your wiring first.

This module will come in a sealed bag and once opened it can not be returned.

There are three different 4-port modules and several different 3-port modules.

The newer version is a 3-port, but you would need a different light harness to use that.

On the label they say "PH F 26400 W 26385 PN 26134".
