original wirng vs. American Autowire

[SFTorange]

I have an American Autowire Classic Update harness installed in my truck. It is a great kit, and I highly recommend it. I'm trying to figure out the best way to install trailer lights on my truck, and I found this great product from M&H Electric, but I can't tell if it will work with my classic update harness. Could someone do me a big favor and take a picture of the original socket where the rear tail light harness connects to the intermediate harness? I can't tell enough by looking at the pictures online, and I don't want to bother buying something that won't work. My AAW harness uses a square connection that looks like the one in this picture. Will this connector mate up with the original style connectors that come with the trailer harness from M&H.
