Not yet, when I came up with the idea I was at the dealer for something else, started looking at the JK's and it hit me. The one I was looking at was stock and I couldn't get my head far enough into the fender to see exectly what was up, but it appeared to be almost indentical plugs as the TJ's front blinkers. So I ordered a set. They only list for something like $16 so if it doesn't work or I can't make it work I won't be out much. If I have to then I will get the proper plugs and splice them into my factory harness.
As far as your question, I would think it should be a simple mod after locating the correct wires to splice.
