Change the cable 12.2 Romex must be the first, then run 12.3 Romex to the light and the second switch.

The 12.3 Romex cable has more than one traveler Name (usually red) required for 3-way switch.

12.3 The neutral (white) Wire will be directly connected to the neutral gas of 12.2 and the son son of a copper base connected together with wire nuts.

The lamp should be two extreme Romex 12.3. A End of the first switch from the other end of the second switch.

First connect the child and mother is a copper ground wire to get them off the beaten path, then the son of two red-long trip with a wire nut.

Discover now the black wire from the first box and the white wire in the second field and its Connection with wire nuts.

This is a practice quite common for the three and four-way switch.

Now, the second switch to the red wire to the passenger terminal link on the left side. White Cable, now called black tape, it connects to the upper limit of the law. The black wire connects the lower right terminal. Copper Wire a connection to the field if it is a metal box or even the green grounding screw with the switch when the box is plastic.
