@1536Z4 , all you need is there except this wire which you should be able to recycle from your existing wheel.
View attachment 292829Then you need to join the two plugs with red/green/brown wires together, and join the plug attached to the above wire to the black plug with white/yellow wires. Like this (the tiny plugs are attached to the paddles, but you shouldn’t need to detatch them)
View attachment 292830The bare wire attaches to the earth screw on your steering wheel. The white plug plugs into the slip ring. You shouldn’t need an electrician for this, there’s no cutting or stripping.
If you can’t find the spare wire in the first picture (to be honest, I can’t remember where it comes from), you should be able to just pull or cut the black plug off the yellow/white wires, attach yellow to the earth screw and tape up the white wire. The only problem with this is you may need to extend the yellow wire.
