Thanks for your input. I managed to find out there is rubber plug in way on 1997-2003 pontiac models. Pull out the plug inside of soft grommet and then poke screwdriver, coat hanger, or fibreglass stick through and run your your power wire through. Extra info for plug: I used screwdriver to pry it up then grabbed with pliers to pull out. It is split in two pieces. You will see when you pull it out.
