Need walker implement wiring assembly.

[Sunset LC]

Hello, I need to locate the walker implement wiring package. I'm wanting to hook up a snow blade to my 05' MB and the only route I know to go is to locate this wiring package. Maybe there's other ideas you may have .I'm open to suggestions. I have this wiring package on my 10' MTGHS so thats why I'm assuming that I can use the same one on the MB. thanks
