Great question. I didn't (the switched are dummies in the panel). Haven't figured that out yet. I have another issue also, and that my fogs arent turning on with the switch.

The headlight switch appears to have the ability for the fogs, it should work right?

Is there a way to change out the rocker siwtches in the panel or do I have to purchase the correct panel? ($200 on ebay right now). Not a huge deal since I live in SoCal but don't really want to lose any functionality in the interior if I can help it.
