Headlight switch wiring question

[iufan71]

Hello everyone,been fixing little things wrong with my truck,and have replaced the dash bulbs,and rewired the courtesy lights and door pin switches. I have everything working,except for the ability to turn on the interior lights,using the headlight switch, without opening the door. What two wires off of the headlight switch do i need to tie into,for this to work correctly? There is like 6 or 7 wires coming off the headlight switch itself,and i dont want to cut the wrong one. Any help is appreciated. Thanks.
