New to the site here and any forums for that matter. I have an 08 Santa Fe GLS very basic and boring and stock lighting is not the greatest and no fog lights. I purchased oem replacement housings I have them installed already along with a relay and fused harness as well. I’m using a factory OEM Hyundai fog switch to keep everything as clean as possible. Illumination of switch is hooked up and working. I have all the schematics and wiring diagrams and understand reading them for the most part. So like I said grounds are all good. Constant power is supplied and I have tested and can get them to turn on as well. Where my issue is I only want them on if headlights are on so I tapped in to multi function switch harness for when headlights ore on so I thought. They only work with headlights off and power is cut when they are turned on. I can easily tap ignition power source to run but rather have with headlights. Can someone with a bit more experience help me find the pin I need to tap? posted_image

Pin 15 at the headlight switch is at 12 volts any time the switch is off or in the parking lights position. It goes to ground when in the headlight position. You need to make sure your fog light switch controls a ground as well.

So what pin would I need to be on to have 12v when in headlight position? I have a ground off of switch and off of relay. Pin 15 is what I tapped into. posted_image

I think I may have figured this out. Would running my negative to 15 then my hot to ignition 12v source get the give me my power to fogs while headlights on?
