On the garden hose: fit the shutoff valve and female adapter. On the spray nozzle and Controller inlet: fit one male tip to each compatible connection.
Close the valve. Disconnect the hose from one attachment and connect it to the other. Reopen the valve once the connection is secure.
This kit controls and changes the connection at the garden-hose end. Engine-brand Quick Connects and permanent Reroute plumbing serve different parts of the setup.
