Step 4: Connect the Traveler Wires
Choose one of the traveler wires and connect it to the red wire on the dimmer switch. Connect the other traveler wire to the black wire on the dimmer switch. Use wire nuts and electrical tape to secure them in place.
Step 5: Install the Dimmer Switches
Install the dimmer switches back into the wall box and secure them with screws. Make sure the wires are not touching each other or anything else.
