No Problem.
They are very useful for switching the pump. It is subtle difference to your current unit DE the pump when you stop flow.
With a radio remote the pump is switched on/off reducing your battery draw slightly. The two brown wires break into the Red cable between the VS and pump.
What you will see is when the remote is pushed it will take a couple seconds for the flow to stop, this is because the Pressure in the hose line is draining off, on restarting the pump it will take the line a couple seconds to re pressure and flow to start again
