STEP 1:
IN THE FOLLOWING TESTS: Separate the wires far enough to be sure the alligator clips will not touch each other,
connect the Switch Wizard as shown in the pictures and press the button on it. Follow the steps.

At one of the 3-way switch locations connect the three switch wires together, as in the ( AT 3-WAY # 2 )
example below. If there are any 4-way switches connect all four wires together at each of the 4-way switch
locations as in the ( AT EACH 4-WAY ) example below.
At 3-way # 1 connect the three tester leads to the three switch wires, it does not matter which lead goes to
which wire.
Press the button on the tester and two LEDs will light. Mark the switch wire connected to the tester lead
that DOES NOT light up as in ( 3-way # 1 ) example above. Use one of the supplied markers, or a piece of
tape, whatever you want, just keep track of which wire it is. This is the “common” wire for this switch.
DO NOT INSTALL THE SWITCH YET, CONNECT THE OTHER TWO WIRES BACK TOGETHER
MARK THE WIRE THAT DOES NOT LIGHT UP
YOU SHOULD HAVE:
Identify the common wire for 3-way # 1 test
OVERVIEW: A basic 3-way switch circuit consists of two 3-way switches. Power goes to the
“common” terminal (the black colored screw) of one 3-way switch. Two “traveler” wires go from
switch to switch, connecting to the brass colored screws. The wire to the light goes to the
“common” terminal of the other 3-way switch.

A basic 4-way switch circuit consists of two 3-way switches and one or more 4-way
switches. 4-way switches have two brass colored screws and two black colored screws.
Power goes to the “common” terminal of one 3-way, also two “traveler” wires from it’s
brass colored screws go to the 4-way switch’s brass colored screws. Another two “traveler”
wires from the 4-way switch’s black colored screws go to the two brass colored screws on
the second 3-way.

STEP 4:
STEP 3:
STEP 5:
On the 4-way switch two screws will be one color
(brass), and two screws will be another color (usually
black). Connect the two marked wires to the brass
colored screws, the other two wires to the other color
of screws. GO BY THE COLOR OF THE SCREWS NOT
THE PHYSICAL LOCATION ON THE SWITCH. ( varies
from brand to brand )

IMPORTANT – the two unmarked wires at 3-way # 1 must be connected back together.
Also, all four wires at each 4-way switch location still tied together.

YOU SHOULD HAVE:
AT 3-WAY # 2 CONNECT THE TESTER
Now at 3-way # 2, connect the three tester leads to the three switch wires, Press the button on the tester and two
LEDs will light. Mark the switch wire connected to the tester lead that DOES NOT light up as in ( AT 3-WAY # 2 )
example above. This is the “common” wire for this switch. IF THERE ARE ANY 4-WAY SWITCHES CONNECT THE
OTHER TWO WIRES BACK TOGETHER. If not go to step 5.
IMPORTANT – Connect the unmarked wires of 3-way # 2 back together.
AT BOTH 3-WAY SWITCHES, THE TWO UNMARKED
WIRES TIED TOGETHER
YOU SHOULD HAVE:
At each 4-way switch, connect the tester to any three of the four switch wires, push the tester button and two LEDs
will light. Mark the two switch wires connected to the tester leads that DO LIGHT UP. These two wires are a “traveler
pair” . If there are more 4-way switches, connect all four wires back together again and repeat this step at each
location.
AT EACH 4-WAY LOCATION
MARK THE TWO WIRES
THAT DO LIGHT UP
At both 3-way switches the marked
wire goes to the ODD COLORED
SCREW, ( usually black )
referred to as the ”
common terminal”
The other two wires “travelers” go to
the brass colored screws, one wire to
each.
Install the switches:
marked wires to the
brass colored
screws, one wire to
each.
