How do i connect my 'unofficial' alexmos gimbal controller to my SPF3 EVO flight controller?

Hi, I’ve just got a new SPF3 EVO flight controller to replace my SPF3 in my current quadcopter. I haven’t wired it to anything at the moment. I also just got a carbon fibre gimbal off ebay and the gimbal control board is identical to one show on a different thread (pictured below) however having read the thread I still don’t think it answers my question fully.

Thats what my ‘unofficial’ gimbal controller looks like, I want to control the pitch angle via my flight controller (pictured below).

I’m not sure how to wire the gimbal controller to the flight controller so that I can control the pitch of the camera from my transmitter. The diagram below seems to show this but the gimbal control board and flight controller are slightly different in the diagram so I wasn’t sure what to do…

Any help would be appreciated…
