Hospital Bed Control Box Schematics

We need a lot more information. Let’s start with what hospital bed? And what controls do the box have? Where (what country) is the bed going to be used? And so on…

 

Hi There I'm looking for a schematic for Okin Model JLDP.03.021.000 they are all much the same. On the board I have there is third connection on the head and foot motor plug the down relay will operate but the up relay will not lock in there must be something in the motor plug that bridges across to the 3rd wire any help will be appreciated I have marked the extra pin with a white arrow the controlling IC is a PIC16F886-1/SO Cheers.
