Mode 3 is what you need. Been a while since I did a mode 3 but if I remember correctly; Gear and doors you wish open gear down connected to the EV5U, doors you want closed connected to the additional valve plugged into "door 2" port on right side of valve. Then simply program timing for G0, D1, D2.
When you start the programming, it is very important to make sure you have the valve in the correct sequence to start with. Brakes only function gear down so test them before beginning the program. If the brake valve does not function your switch (or channel) is in the wrong direction; reverse the switch (or channel in radio if switch is in preferred direction) before you begin the programming! Many make the mistake of starting the programming sequence with the valve in the wrong position.
