Ok, anyone looking for a harness for your '07 Wrangler with the Infinity system it is avalible. Here is the information I have. Metra says they have it, Part # CHTO-03. From what I understand you have to buy it from an authorized dealer, price is unknown at this time.
Also I found that Autotoys.com has a Chrysler factory part, Part # Chrysler C2R-CHY that they claim , Provides accessory output, reverse signal, Park Light signal,Vehical Speed Signal and Parking Brake output. This unit will also turn on the factorydata controlled data amplifier if so equipped. They say list price is $135.00
