Rewiring Truck.

 This time I am wiring it up using toggle switches initially. 

I will attempt to use two or more ESP32 / Relay combos to "Smart" the system as plug in modules. 

Th speaker system also needs replacing. Blue tooth was annoying at times but mostly very stable. I will likely use the module with the 3.5 mm phono from the back of the monitor so as not to need bluetooth at all.

Still waiting on components from Banggood as is usual with them.
