Where have you guys been tapping into the frame for your grounds? I have take the lining out of the trunk and have not seen any where I can just loosen a bolt and running the ground wire without having to drill a new hole. Any insights will be greatly appreciated, thanks.

 

I don't have a picture, but I put mine under a bolt immediately behind the rear seat. IIRC, it was close to the hole in the middle.
