I got the complete kit from Subimods for my 12 Sport Limited and it worked fine. Just a word of advice, make sure you use the OEM relay in the Supertones kit and NOT the one with the harness kit. When I had mine installed we used the cheapie relay and it worked for about 5 minutes and then stopped. Pain in the ass to troubleshoot and we were checking all the fuses and connections. Then we swapped out the relay with the OEM one and it worked without a hitch.
