Wire Harness advice/help

I am looking for easiest way to replace my under dash wire harness and found the one in the link below.

Does this one need anything other than just plugging in? I cannot compare the pic to the actual very well, and wanted to know if others bought this one and how did it go?

thanks in advance!

that's a M&H harness.. best stock style one on the market today. as long as its correct for you application it should be plug and play.

look over your stock one first though. what could get damaged sitting in a box?
