Has anybody been able to get a hold of any wiring shematics or diagrams. Looking for some stuff to hook up an Alpine Nav unit and i need speedsense, etc. most of this stuff is all data-bus driven (damn new cars) and PAC or Metra havn't even begun to work on an interface box yet. "2007 Jeep? nope havn't even gotten one of them into R&D yet. The Escalade people are more important." Thanks!
