ddm likes to do this thing where they reverse the wiring on the plug that connects to your factory harness. what you want to do is pull out the wires and swap them. there's a small release tab inside of the plug which allows you to pull the wire out, kinda hard to explain. here's a pic to show what you can do. either A) pull back the retaining tabs so that you can pull out the wiring and switch them, or B) shave off that plastic nub that prevents you from plugging in the plug the other way.
of course, first check to see if this is the issue, if your black wires don't match up with your kit and factory harness, then you know this is the issue.
