Can someone help me with the following electrical issue I am having? Any information would be greatly appreciated.
I have an outside porch light that is controlled by two 2-way switches in two seperate enterences of a multi family that I own. (The entrances are side by side.) The power is coming into one switch on side A, then to the light, and then to the end-of-the-run switch on side B. Is there anyway possible for me to add an additional switch at the top of the stairs on side B so that the run will look like this...power to side A switch - to light - to side B switch - to 2nd side B switch. Can anyone help explain or send a diagram?
