I just installed mine on my 17 this weekend. I put it under the trunk. Open the back panels, (the one with the license plate, and the one above that. Cut through the insulation on both sides where the wires go up into the tail lights, and find the Green wire, with Red stripe. There's also a screw right there at the top that worked as a ground. Mount the unit to the left, not dead center, under the trunk. You have to wiggle it a little to get it in. If you mount it toward the middle, you wont be able to get the cover back on. Then use electrical tape to seal everything up. Mine is the BACK OFF - WIG WAG, and it worked for many years on my 06, and now it's working fine on my 17.
