I'm in the same boat with a 2008 jeep compass. Now I'm looking for the possible solution that I just got the lead to through the fortin app. It says something about modifying the male side of the t harness and need to cut the yellow and add the yellow/green from the evo. It says to see the installation instructions for directions but I cannot find them anywhere. Hope someone with the answer can chime in. This is supposed to apply to chrysler/ jeep 2010 and below?
