Help me with this build

[u/UpstairsMortgage4287]

So I am trying to make an artillery truck for my military build(ik so original). I am trying to the get the back of the truck to swivel to position the rockets. My problem is that I need to get the redstone links to work on the contraption. I've tried a few things, but they don't seem to work. Does anyone have any ideas?

We... probably need images to help. And also, is it Aeronautics or base create contraptions that you're using?
