TIP

If you notice that the Dump Valve is going in the wrong direction, you have to swap the wires in the Arag connector.

If the Dump Valve connector is on the Sprayer Harness, then an adaptor will be required to connect the 4-Pin Weather Pack to the Dump Valve. You must connect the correct adaptor to the Dump Valve. See Table 5-1 on page 5-24 to determine which adaptor you should use.
