Update 4-26-2016: We have since suffered sort of a crash and cannot recover the photos below. Instead, we’re going to just post a picture that we just took from our Mac Mini stored on our shelf.
Hope this helps, as we recently received a email asking for wiring details.
Ok, so here’s how we did it, however we don’t like re-inventing the wheel (rather then to improve on it) we going to refer you to ifixit.com on disassembly first.

Please do steps 1-14, and 22. Then come back here.
After you have disassembled your Mac mini, remove the power supply and re-assemble everything like so. Reconnect the power supply on the outside of the Mac Mini.
1) Cut the positive wires, and the Negative wires. Note the Middle wire:
2) Solder Pos wires together, and solder Neg wires together.
3) Find a wire and solder to it to make leads longer:
4) Solder the other end of the wire to a Panel mount DC jack:
5) Run it to the back of the Mac Mini where the AC cable used to plug in:
6) Find a Car cig plug (we sell them) and solder it to a 2.1mm plug:
7) Here’s how it looks fully assembled.
8) Plug in to the Mac Mini and you’re done!
NOTE: We tested with operating voltages of 10v all the way up to 15vdc, however we STRONGLY recommend you use a voltage regulator. Please contact us.
