Controller-Electrical-Schematics
The PCB was designed in KiCAD and manufactured by OSHPark. It's essentially a giant shield for an Arduino Mega that drives many Power MOSFET devices, and conditions the inputs from the car. It also has many connectors for illuminated pushbuttons.
Many through-hole components were used for ease of assembly, and overall design simplicity.
The following diagram describes how signals are moved through the system:

Questions
How big is the Hitchco mk4 PCB?
It measures 181.7 × 131.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Hitchco mk4 use?
217 parts, built around the NCS3S1205SC, LM358, SN74HC595N and CD4013BM. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Hitchco mk4 KiCad files?
From the mk4-dd/Controller-Electrical-Schematics repository on GitHub, at the commit this page was made from: the board is kicad/hitchco-mk4.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hitchco mk4 design in my own project?
Its repository states no licence, so its author keeps all rights: ask mk4-dd before reusing the design.
