Instalation of cruise control-does existing control modul support it?
 

HI,
I have intention to install a cruise control on my Audi A4 Avant 1.9 tdi 2004 year. This evening I had taken a few pictures of control unit (J 527) and his part number is : 8E0 953 549 S. Does this control unit support cruise control? By the way, my car does not have multifunction steering wheel neither phone integration. I try to count the wires which enter into control unit (without disconecting, it was difficult to count) and there are 12. Do I need to add some other wire from unit to some other place (for example engine control unit) and where or I need only to add a cruise control handel and to reprogram engine control unit?
Thanks for replies.
