Here is a new 61590 wiring set up for vehicles with HB5 headlights (the plastic lenses with a replaceable bulb) with Western Unimount or Fisher MM snowplows. You will get the 9 pin relay style control harness 61437, headlight harness 61591 Western or 8269 Fisher and parts bag 61559. If you don't have the power harness, you will need to add that to the cart, too. Don't forget to add a tube of dielectric grease to protect these plugs. Take a look at the headlights in your vehicle. They will have some #'s stamped in the lens. Make sure it says HB-5. If you have a '97 and newer Ford, they recommend you use kit 63420. This has the 61185 overload module.
Western is sure proud of their wiring harnesses, as reflected by their pricing, but in no way Storks fault. A good company to do business with. Thank you Storks
