I bought my SAFC-II off ebay back in july Brand spankin new for 265$ and then bought the Harness from Buschur for a buck... deff worth it .. no messin up the factory wiring.. I got my settings from DB so i didnt need to do any driving around... (only becuase i have buschur parts)... I think shopping around on ebay is not a bad way togo... hell most places are selling them for 340-370 ...
