    I can't tell from the picture but is there a cover on the end of the plug? Sometimes the manufactures run a wiring harness to cover differant options and maybe it wasn't used on your truck. If it doesn't have a cover then just take the plug and move around the area that is the length of the wire and see if you can find a matching plug. Hope I explained that so you understand.

    Yes, I just went out side and did that, The wire / wire loom runs in front of the radiator base and looks like it might mount in a bracket/L shaped metal bar that runs infront of radiator. still not sure what this is for??

    But does it have a cover on the end of the plug or is it a open plug?

    Some models had a horn right in front of the radiator. That's what the plug's for.
