Traction control switch, custom
 

Long story short I have a custom control panel with a TCS switch, I've read a bunch of threads on this already. I've trialed and errord it, but its raining heavy out and I can't tell if the TC is kicking in or not. All I need to know is which wire to install the switch into, here is the diagram I was looking at. I just want to make sure I put it on the right one, whichever one will work or whatever one goes to the fuse panel so I can turn it either on or off and not have to switch it off every time I start my car. Thanks
