ldunning,
Bummer! I understand that there is no set wiring diagram. Check the connector under the slide, (Sorry, I am not familiar with your unit, if it was a 3400RL, I know that one) On mine, there is a plastic push together connector, under a carpeted board under the desk. Access is Two screws, the carpeted board comes off.
Get a proximity detector, a pen like plastic instrument that makes noise and sometimes lights up (different ones) when set next to a hot wire. (Lowe's, Home Depot, )Then check under the slide where the SO wire (Black rubber coated like an extension cord) runs. Or, take the cover off of the 2x4 box and check it.
Good luck.
