I have a 2007 outlander which has a mitsubishi multi communication system in it not the factory unit which I want to replace I have taken it out and brought an aftermarket stereo along with the wiring harness for my year outlander which was meant to make it plug and play but it does not seem to be the case has anyone else replaced there system and has any suggestions on how to do it I’ve replaced stereos in other cars and never had this kind of trouble
