I was wondering how do i get the fake switches out to install a real one. I bought another stock fog light switch from toyota to use for after market driving lights. On the back of the fog switch there are four contacts. I'm guessing possitve and negative to make the switch light up, and the in and out hot line for the switched light. Which one is which, does any one know? Also, what wire do i need to tap into to get the switch to light up when then head lights are on, like the other stock ones do?
