When I ordered my H3 last year, I could have sworn that it had that code on the order form option list.
My dealer has on all of his stock, and my truck was delivered with, the two white plastic mollies that plug into the square factory manufactured holes in the front and rear bumpers.
I think that's what the code refers to.
those two extra mollies.
I think that One plate state vehicle owners just have the square holes w/out any mollies in them.
