Hi!

We have a pull chain light in our laundry room. We want to replace it with a regular light fixture and add a switch. We have a diagram and it seems straight forward.EXCEPT:

This light isn't an end of run. Tapped off of it is a receptacle (which is the end of the run)

If we wire up the switch and light is our receptacle then going to be controlled by the switch? We are turning this into an office so we need the receptacle to always be hot.

Is there a way to keep it tapped off the light or are we going to have to reroute it to tap off the switch?

Thanks!

All you need to do is add a switch-loop to your existing fixture box. You will have the existing two cables in the fixuture box (power in & power out to receptacle) plus your new switch-loop cable.

Install your new switchbox and wire the switch. Put black tape on the white conductor and connect the black and taped white wires to the switch.

At the fixture box, disconnect any existing wiring. You now have 3 cables and a total of 6 wires(not including grounds). Strip any unstripped wires. Mark the white wire from your new switch-loop with black tape. Also, prepare a 6" white pigtail wire for use as noted below.

Start with the grounds and connect them together and bond to the box if metal.

Next, tackle the Neutral (white) wires. Wirenut the white wire from the "power in" cable to the white wire in the cable going to the receptacle and also to your 6" white pigtail wire (3 wires total). Just leave the pigtail wire dangling for now.

Now, connect the HOT wires. Wirenut the black wire from the "power in" cable to the black wire in the cable going to the receptacle and also to the white wire with black tape in your switch-loop (3 wires total).

You now have a black wire and a white pigtail wire remaining. Connect the black wire to the fixture's brass screw or black wire. Connect the white wire to the fixture's silver screw or white wire.

Now your receptacle will be constantly powered. You may need to replace the fixture box with a deeper one to accomodate the additional wires.
