Leggett And Platt Adjustable Bed Where Do I Plug In The Remote For My Adjustable Bed?

Where do I plug in the remote for my adjustable bed? - leggett and platt adjustable bed

I bought an adjustable bed (no mattress, remote control or manually) in a fire sale recently. I let the remote control of Leggett & Platt (creator of the bed), but can not find a place to connect the remote connection. How can I find information online or see an online manual? I searched but found nothing. The bed is a model number S Cape Tempurpedic 81,908 achieved in 04/06. Thank you.
