The white wires are fine, power wires look good.
I don't see an air inlet tube -
It doesn't really matter which way the air goes through the chamber, you just need one Inlet and one Outlet. You want them both to stick out of the case, so that if the airflow ever stops (clogged injector, dirty spa filter, clogged check valve, pinched/kinked tubing or other problem) the ozone will not fill the case and eat the guts alive.
