I think we keep finding the same things,akirby! I've been all over the Internet and I'm starting to think I'm going to end up having to install what I get, have it activated,and try it. If it's a no go, I'll assume I need the interface kit. I'm almost thinking hopefully the interface kit is needed on the older models? I can't find out what constitutes needing to bypass the PATS system. I know this plug and play model is discontinued and ford has started selling these kits by the piece, so I guess that's why I can't find a definitive answer. I was just hoping maybe someone here had installed this kit on their similar Edge and could tell me how I find out if I need the interface kit or not. Thanks for helping me search though.
