WANTED --> W.E. 6000 series adjunct key assemblies BSP

[Babybearjs]

does anyone know where I can find a BSP for the old WE 6000 series Adjunct Key assemblies. I have the schematic pages for from the buyers guide, but am wanting to find out more info on them. I have the 6021N which is MD and the schematic only shows the wiring for the 6021DN. I'm rewiring mine and am going to have to add a additional TS to accommodate the A-Lead wiring.
