It was probably mine.
I just spliced the MyColor stuff into what was already there. So the door lights were spliced in to the lock/unlock switches. The foot wells and the cup holder were spliced in to the Auto shifter gear lights. The door sills were spliced into the Dome/Map lights.
Cluster kinda worked on its own. Only thing I couldn't do was change the color of the lights (besides the cluster of course), unless I re-wired stuff. Which would not have been hard. But the only color I preferred was Blue so I left it like that.
If you have a manual trans, you are on your own. No idea how to get that to work.
I did almost a full Premium swap on my 2014. Right down to the Shaker faceplate and pedals.
