GFI wiring with associated light switch

Customer Question

I need to wire a GFI in my bathroom and there's a light switch that's associated with the box. The original wiring has two separate cables coming in, one from the lights down to the switch and the other to additional receptacles in an adjacent room. The original wiring scheme has one cable's white and black going to the top receptacle and the other cable has the black going to the light switch, the white going to the receptacle. They ran the other side of the switch to the black side of the receptacle. Given all of this, what is the best (correct) way to now replace the old receptacle with the GFI???

YOU WILL BE OK BY PLACING THE GFI IN LINE AT THE BOX, IF YOU REMOVE THE TAPE ON THE BOTTOM OF THE GFI AND PUT OTHER OUTLETS ON IT FROM THERE THEY TOO WILL BE PROTECTED. YOUR LIGHT WILL NOT BE IN THAT LINE FOR IT WILL BE BEFORE THE GFI. AGAIN. NOW IF YOUR LIGHT "HOT" IS IN THE OUTLET BOX JUST CONNECT THAT HOT TO THE TOP BRASS SCREW ON YOUR GFI. YOU DO KNOW BLACK WIRE GOES TO BRASS SCREW, SILVER SCREW IS FOR THE WHITE WIRE. IF YOU NEED ANYMORE HELP PLEASE ASK. THE KEY IS HERE IS THAT ANYTHING BEHIND THE GFI WONT BE PROTECTED WHERE AS THE GFI OUTLET ITSELF WILL BE PROTECTED, AND ANYTHING AFTER THAT POINT ON THE SCREWS THAT HAS THE TAPE ON THEM.
