Fyi i have the same thing going on with a switch by the kitchen and one at the bottom of the basement stairs removed a snarl of wires and now the 3 way switch has to be on at the bottom of the stairs in order to work from. The first way of wiring uses a couple of two way light switches with a 3 wire control. Most likely you have a 14 2 coming from panel which you can think of as the main body of a tree. Active 3 years 9 months ago. A three conductor cable with a ground is then installed between the two 3 way switch boxes. I ve got a light downstairs with the switch upstairs. All the blacks and all the whites are tied together meaning you have 2 hot wires leaving the box and two neutral wires leaving the box.

None are hot unless the other light switch is turned on in which one of the reds is hot. I am confused because it worked before with an old school 3 way switch and the same wire going through the wall i only removed cables that were downstream as it were.
I have a 3 way switch with 2 red wires and 2 black wires and a ground and trying to figure out which wire goes where.

Since only one wire and the ground are used the other unused wire is capped off and saved for possible future use. Active 3 years 9 months ago. I ve got a light downstairs with the switch upstairs. I think that the most common method used to wire a set of 3 way switches is to bring the two wire line cable into one switch box and bring the two wire load cable into the other switch box. Notice that there is an unswitched hot and neutral at both switch boxes. None are hot unless the other light switch is turned on in which one of the reds is hot.

You can observe in the schematic that both the com terminals are connected together. This method is depicted in the diagram at the top of this post.

The hallway light may be on a 3 way lighting circuit but not all of these wires make up that connection.
