Whoa! That's awesome! I also use Deutsch DT 2-pin connectors for all my upfitters (and a 12-pin DT for connecting to all the upfitter wires on the firewall). Does that plate allow 2-pin DTs to slide or snap to it, or is an additional fastener involved? Where you plan to mount the rail? I've got all my DTs tucked between the battery and the firewall.

The connector slides into it. I made it snug so it slides in and bottoms out. I plan on mounting somewhere on the firewall back behind the battery. That's where they are currently tucked at. Here is the rendering to help see it a little better. I figured this would clean up the connectors just laying behind the battery.
