Trying to wire the bathroom light switch, but vanity light will not come back on. There are two wires, black and red, plus a ground wire that wasn't hooked to anything originally just touching the side of the box. The black and red wires were stuck straight into the back of the switch that went out, not wrapped around the screws on the side. I am at a loss as to what to do. The red line has been dead until just recently when I got a second new switch to hook everything up to. The red wire is now currently hot after not having been so during my previous attempts.
