ABS-"Off"

Good evening.
I'm gonna have to ask you guys a question of electrics. I want to be able to switch on and off my ABS. Could any of you write me how to do this cable? Unfortunately, the original circuit with ABS switch is not drawn in the circuit diagram. But I found a pre-assembled plug behind the switch bar in my V8. Does who know what he's for? Could be that the switch for ABS was only ne' option and was not plugged in. Is it possible to use all switches of the V8 or are they different? Thank you for your help.
PS: ABS in winter feces.... To me. That's why I want to deactivate it. LG Martin
