2 old white and black wire house wiring. It is usually a white wire. Red wires are usually secondary live wires in circuits. When you connect an outlet or light switch the black wire goes to the brass screws.
You can retrofit your 2-wire outlets with new 3-wire receptacles without any rewiring but the box must be grounded. The pigtail will go to the copper coloured screw on your light. The old colours were.
Never attempt to use a black wire as a neutral or ground wire. This was the live wire. Black Red and Green with Yellow stripes.
This was the neutral wire. The ground wire goes to the green screw. Now go up to your light box.
A ground wire is used as a protective measure. White Wires With Black or Red Tape. So can I extend the black and white from the existing 2-wire receptacle to new location and install a 2-wire outlet or GFCI outlet but leave the romex ground not connected at each end.
The light switch wiring looks like what I would expect - neutrals wired together black wires to the timer ground to the box. The oldest type of wiring system found in homes is called knob-and-tube named for the insulating knobs and tubes are used to run the wiring along and through the house framing. Red wires are commonly found in sheathed multi-conductor cable.
