Hi, i know the post it is from 2010, but, i bought a Journey R/T (2010) in Brazil this year (2014) and i have the same problem.
I found a solution, i bought a connector from Positron, factory in Brazil. The connector is the Pronnect 440.
The instalation is not so easy. It`s necessary the guide factory and one person who really understand about eletric parts of cars.
