That is what we did. Often with solid core wires bent round nails driven 
into wood to identify branch points.

Solid core was best for fixed installations where the wires were 
soldered as they didn't have stress concentrations at the soldered joint

Then the loom was held down with cable ties - not zip ties - loops of 
plastic with holes at the end for a screw

Surprisingly cheap compared to today's prices for looms. Minimum wage or 
piece work by home workers in the consumer industry...serried ranks of

(Flexible) PCBs today are cheaper.  I remember trying to get everything 
to mount off PCBs by the late 1970s...
