Good luck. A bit of patience is key. Using a small jewelers screwdriver and/or hobby knife or something similar to pop the housing lock points can get it done. Even though it may not apply to the OEM kit, take a look at/download Jeepguy's PDF directions in the OP just as a reference for the connectors. He had some good descriptions for getting some of these connectors apart. There are also a few close ups of some of the connectors in
my earlier post and throughout the thread (if you want to dig) that may help.
And thanks to cptwing for sharing the rear radio connector and pins b/c I was able to locate the following under one of his links that may also help.

If you run into problems, be specific about the connector and step you are on, perhaps post a picture/close up, etc, and hopefully someone can help you out.
Hopefully this doesn't seen out of line, but since you are using the Official kit from Ram, it may be better for you to post in cptwing's thread since that is what it specifically deals with ...
