As I suggested in the PM I sent you. MAKE SURE THEY'RE SOLDERING! I can't count the number of times a steering wheel controller would not work because of the resistance because of some kind of crimp or t tap. Also, make sure they grounded the black wire in the factory harness as this needs to be done. One last thing I thought of yesterday was that they could only be trying to match the colors and not counting the pins from the wiring side. Check that as well.
