am rying to reroute electrical

ok I believe I made a mistake. I have rerouted some light switches to a different wall as we are renovating. First of all do I have to run new wire in attic if the existing wire isn't long enough? and one of these wires has 4 wires in it...what am I supposed to do with the red wire and how come no one ever mentions a red wire when dealing with electrical??? I know I am new at this, but I really did think I was kinda handy till I started this project...Any help would be greatly appreciated...

Wiring cannot be just spliced together in the wall. You may have to make a new run to the attic and put in a JBox. The Red wire belongs to a 3 Way Switch circuit.

thank you Zack

Thanks again, but does the red wire get put together with the black wires? or the white?

The red wire denotes most likely a 3-way switch. (Does this light turn on and off via 2 or 3 different switches? You'll need to extend this wire using 14/3 or 12/3 wire (the 3 denotes three current carrying conductors (black, white, red) plus a ground). If you try to extend it with 2 conductor wire, you won't be able to make the multiple switches work correctly.

As stated, you need to make the splice where it's accessible in the future, so it needs to be an accessible place in the attic or similar.

I'm sure you're also using the same guage wire (14 or 12 guage depending on the circuit size).

Three-wire cable, with that pesky red, is typically used in two situations.
One is going from a light fixture box to a switch box that contains switches for other lights. In this case the while wire is neutral, the black (usually) is carrying unswitched hot to the switch box to feed all the switches, and the red wire is returning switched hot to the light fixture. If all your old switches have On/Off labeled on them, this is most likely the case.
If you have an old switch that has no on/off labels, and has more than two screw terminals on the backside, you have three-way switching. In this case the three-wire cable is usually running between two switches, with the white wire carrying unswitched hot out to the second switch, and the red & black coming back switched. Yes, I did say the white wire is hot... in order to make it Code, it should be tagged black on the ends with permanent marker (tape isn't permanent).

I suggest starting from wherever the run coming from the panel is, and drawing out which wires go where. That should make it clear pretty quickly where you have more than one hot going between two points.

Thanks to all

I think I have it...yes I have extended the wires with the corresponding and correct size wire. I once again thank all that has seen fit to help me in this matter. I greatly appreciate your correspondence and am indebted to your generosity.
