Horn doesn't work, do I need to pull steering wheel?

[emil77]

Hi guys,


The steering wheel in the picture below was put on by the previous owner. The horn hasn't worked since then, I'm thinking he forgot to connect something. When I put power to the horns inside the engine bay, they work. So somethings wrong with the steering wheel part. Do I need to remove the steering wheel, in order to work on the horn?
If not, could you please tell me how to remove just the area I need to work on for the horn? Can I pop off that center piece and the horn contacts will be exposed? If I do need to remove the steering wheel, use a steering wheel puller correct? Are there screw/bolts I need to loosen/remove first before pulling the steering wheel?
