Db Br 187 Pantograph Selector

Can anyone help me find where is the pantograph selector on the Skyhook DB BR 187 loco addon?
I've tried looking around the cab and inside the loco behind the cab doors, but can't seem to find the switch to select the pantograph. I want to switch between front and rear pantographs.

 

You will need to use the Displays shown in the 187

 

Can you pls say where it's located. can't seem to find it.

 

If you look at this video from 20 mins and 14 seconds you will see where to find it
