I recently bought a '93 strat and I think it has a hot rails in the bridge but I am not certain. The only marking on it is a sticker on the bottom with the letters "BC" on it. Is is it a hot rails and is it for the bridge?
well, it is for the bridge. the only way to find out if it is a hotrails is to buy a cheap multimeter (10-15 bucks) and check your ohm rating. It should range out that of the given on the hotrails, + or - 5%.
