This is a headlight adapter for a Blizzard Power Hitch plow. This is NOT for a Power Hitch 2. This is for a vehicle with the HB5 headlights, usually Ford and Dodge. The part # is B62222. There were 2 styles of adapters and they need to match the harness you have. The picture labeled old and new is what you can use as a reference. This one is the new style known as the H13 plug. This plugs in to the 62212 harness.
If you have a harness that has the round 5 pin plug then you need to use part # 62012.
