drl/fog lite

I pulled the fog lite cut-out out and saw a wire harness with a yellow plug just sitting there. I assume this runs to the SAM? Is there any way I can use that harness/plug without having to go to MB to activate it. I am installing an 8 row led lite in there and haven't decided if I want them on for day and nite or just when the head lites are on.

please advise on what you think i should do and how to activate them



thank you for your help
