To aid in wiring the vehicle connections and in future debugging and maintenance, all the cables will have heat shrink labels applied to them as this is a very clean way to label the wires.
Heat shrink labels are typically expensive, but we can buy knockoff labels relatively cheaply and make them work with our Brother label maker with a small modification.
The Brother P-Touch H110 label maker that we have requires a piece of tape to cover the leftmost hole on the cartridge to print on the heat shrink labels to correctly identify it, as shown in the image below.
The heat shrink labels that we purchased are from Aliexpress:
