So on the coach you have black (ground), red (power) and two orange switch wires.
On the fan you have black and red wires.
Connect the two red wires together.
Connect the black from the coach to either of the orange wires.
Connect the other orange wire to the black wire on the fan.
You now have power wires connected together.
And ground connected together through the switch. Switch on will allow the ground connection through the switch to the fan allowing it to run, switch off will 'disconnect' the ground wire.
