JCB 4CX Changeover valve?

[Cobratom]

I am slightly puzzled by a new to me JCB 4CX Precision Control.
I have a separate joystick for the loader, and two precision control joysticks for the backhoe. However I can't get the AUX functions on the loader joystick (electric) to work.
I am used to having a changeover valve on the side dash that allows these functions, but this does not have one.

What am I missing here? Does something else activate it?
Thank you in advance.

What function are you looking to get working? I have a 2006 4CX Precision for about 2 years, I assume that you know that the backhoe will not work unless the seat is rotated back past 90deg and that you then have to press one of the buttons at the front of the joysticks that you cannot see when seated?

I don't have an issue using any of the controls. I have an issue with making use of the auxiliary functions. I can't get the digger extension to work and I can't get the front loader 4 in 1 function to work.

Depending on the type of control for the boom extension it may differ from mine.
My extension works from a flip type switch on the rh seat handle, make sure that the hammer function enable switch is not ON else it will disable it.
For the front jaw open / close, with the seat facing forward you need to press the button on the front of the rh seat handle, then press the button on the front of the crowd control handle on the rh side beside the seat.
It may take a few seconds to engage then operates off a toggle switch on the crowd lever.

That is the functionality I have been trying. Seems to me I have some form of electrical fault that prevents me from actually kicking it on.

This may help to clarify some parts, it's not the information that I was looking for but it does define the types of control to a certain degree.
