Here is a used, working Western/Fisher 26401 4 port Isolation Module. This is the original 4 port Daytime Running Light module that was replaced by the 27781 module. The 26401 and 27781 module are the same. Make sure this is the correct module for your truck and plow before purchasing. You can use Western QuickMatch or Fisher EMatch on their websites to confirm if this is the correct module for your truck and plow. This module was mainly used with Chevy/GMC trucks with DRL. This will not fit just any Chevy/GMC truck or work with just any plow. Do your research or ask me before buying.  This module has been tested and works well. This is a used module that may have dirt, fading, or other cosmetic blemishes on the outside. These modules rarely go bad, so check and recheck your wiring before changing the module. Most of the time, the issue is with the wiring. This listing is for one module unless you increase the quantity to more than 1.  **Module will be marking before shipping and placed in a sealed bag.
