2004 XC70 Harness
 

Hello I've recently purchased a aftermarket stereo for my vehicle and everything works fine, but it seems that there are some loose wires that need connecting.
1.Illumination & its ground connection
2.Steering wheel connection

I have no clue which wires from the car I need to connect these two and would appreciate any help you guys can give me. Thank you! Below I have the link to the aftermarket stereo and some pictures of its connections.
