You can probably purchase the oem switch and change it out. Mine came with fogs so all I had to do was replace them with the led's.
I have the lights from the links above.
No problems and it took about 10 minutes to install them.
If it's pre wired, then you will only need lights, bezels and the oem switch. (it's part of the turn signal lever).
Otherwise you would need the whole kit and you would need their switch and relay.
There are other kits at lower prices, I've seen as low as $49.
I only suggested these because of their quality.
Anyways, I just did a quick search for the oem lever but haven't found anything yet. If I knew the part number it would be easier.
