You have to get yourself the right on-board computer, and do a bunch of wiring (including changing the turn signal stock, if you want computer actuation from there). There's a guy who sells the conversion wiring harness on ebay, and the 18 button OBCs are actually more common on ebay than the 11 button ones. Here's a link with conversion instructions:
