Wiring question

[KFPanda]

I was exploring the Coinless option for my wash and one of the units is a 4 bay relay that I would install in the equipment room. I was hoping I had conductors to spare in the existing wiring to carry the coin pulse to the bays.

What do the 'tokens or last coin', 'coin switch' and 'timed output' do as far as going from equipment room to bay? Can I possibly utilize one of these conductors to hit the pulse wires on the timers in bay?

Those wires aren't used if you don't have their analytics system. The "Timed load" only turns on the light on the door. The "Low pressure air solenoid" is most likely also unused. Even the ground can be disconnected and used. It's a floating 24V AC setup where both legs of 24V are live, you don't want to ground the "common" side anyway. Having a ground to equipment that's welded to the structure is redundant.
