I have a 2003 Audi A4, I had Symp II..no Bose....... I installed a x930bt.....I'm not using a steering module.

 

My question is on the original connector on audi with can-bus L & H (org/vio ; org/brn), being that im not using the module at all , do the can-bus wires need to be connected to anything (wiper, light, etc) when ignition is on or can I omit those wires?
