Crawl Space Ventilation with Wiring and Piping Passing Through

I am currently replacing all of the old aluminum grate vents around the foundation of my house that ventilate my crawl space using Master Flow® Automatic Foundation Vents. They automatically opens at 70°F, closes at 40°. I have two vent openings that previous owners/contractors have passed piping and/or wiring through the opening by making an opening in the aluminum grate.
One was made to pass exterior AC blower wiring through and another vent has a PVC pipe passing through to drain the AC unit. They have created a headache of how to now effectively seal and ventilate these openings using the more efficient system I am trying to install around the foundation.

My question is: Is there a product manufactured to seal around piping and wiring in foundation vents that give a clean look to an otherwise jury-rigged appearance?

I know I could simply patch around these items by using hardware cloth, but I am hoping for a uniform look with the new black Master Flow® vents. I could also hammer drill holes into the nearby brick surface and pass the wiring/piping through, but wanted to explore easier, less destructive methods/products first.

Putting wires and drains through a vent opening is lazy, stupid. They should have put them through the foundation or rim joist.
If you don't want it to continue to look that way you either move the offending issues or just seal up that vent with concrete to match the rest of the foundation. How many other vents are in this area?
