You need to remove that screw to release the wire so that it can be removed with the upper steering mast bearing. If you don't destroy the bearing while removing it, you might be able to attach a new wire to the bearing and reinstall it.
The 2 holes in the steering wheel which are opposite of each other are threaded to accept a steering wheel puller. You need to remove the steering wheel to get to the upper mast bearing.
There are no wires in the steering wheel.
You are missing the spring loaded contact in the steering wheel. It goes in the big hole which should have a plastic tube in it.
