Kwikee step logic

Having just purchased a new Kwikee Sires 28 step for our class C, I dug it out of the box and read the directions. Gee, easy! Right.

Wire colors:
Red - power
Green - ground
Brown - to magnetic door switch, then to ground
White - to switch, then to power
Yellow - to ignition

I tied red, green to my battery, positive and negative.
Step opened,

I expected I could touch yellow or (edit) white to power and have it close. Nope.

So... I thought it was broken, out of the box. I then set up all wires with switches to power/ground per the directions.

Here's the setup:

Power - Red
Ground - Green
Brown - switch - ground
Yellow - switch - power
White - switch - power

Here's how it works:
Connect Red to power, Green to ground, with all switches off - Steps Open. (Door open, Ign off, Override off)
Close the door - Brown grounds - steps close.
Open the door - Brown opens - steps open.
Close the door - Brown grounds - steps close.

Flip override switch on - White to power, Step stay closed. (yep, closed)
Open the door - Brown grounds - steps open.
Close the door - Brown opens - step stay open because White is tied to power.
Open/Close door, step stays extended because override is on, White is tied to power.

Door closed - Brown grounded, Override on, White to power, steps extended.
Turn Ign on - Yellow to Power - Steps close.
Turn Ign off - Yellow open, Steps remain closed.
Open door, steps open.
Close door, steps stay open because override is on.

The basic logic - No matter the other switches, anytime the door is opened, the steps open, if not already open.
If the door is closed, steps stay open if override on, if ign turned on, steps close.

Interesting logic, but it all works. I can see how it's supposed to work now...
