1967 Barracuda center console wiring

Not sure if this helps, but here pics from factory schematic. Unfortunately the console wiring is somewhat vague. Chk for white wire coming off wiper switch.
PS I'm electrically challenged lol.
Yes I will need the sub harness, but right now I am just trying to find where the reverse light power plug is in my existing main harness.
