Running power to a steel tray -Wiring Roof lights, work lights & power sockets & hiding the switches

The new tray for our Project 6 seater Toyota Hilux Workmate is complete and we've fitted some accessories to the tray including roof lights, work lights and two power sockets. We've ran the wiring through the headboard to protect and conceal it and the switches are hidden in the headboard.
In this video we look at how we ran the wiring and wired everything in and how we mounted the switches.
