Dont drill the sheet metal anywhere for a ground wire please!
the sheet metal is too thin to get a decent thread. If u have a sedan, theres a couple of good grounding spots that worked great for me. fold down your backseat, take off/pop off the side cushions. there should be a few 10mm bolts that are bolting the seat belt reinforcements to the frame. these bolts thread directly into the chassis, with lots of clamping force. just sand around the base of the bolt to expose the bare metal. i used one of the middle ones, they're easy to get to, you cant miss them.
