So I got done with the install. Took about an hour. Used this part:

Also the screws I used were #8 x 1" sheet metal screws. I took a few out of other external fixtures and those are the one Keystone used.
I wanted to go right above my water connections, but there wasn't enough room in the water pump space to do it. So I went to the left, then ran into the issue of the furnace exhaust. Didn't want any issues there, so I went even farther left. I'm really pleased with the results. Now I don't have to run my sat cable though the slide seal anymore!!
I got pictures, but not sure how to post them. It wants a URL?
