I now have a single light fixture contolled by a pair of 3-Way switches. The 2-Wire+ground power goes to the 1st switch. I have easy access to the 3-wire+ground cable as it leaves the 2nd 3-Way switch. I want to add another light fixture between the 2nd switch and the existing light fixture. Please advise which wires from the 3-wire+ground cable coming from 2nd switch that I should wire to the new fixture to make a proper connection. Can I simply tap the white and black wires for connection to the new fixture, then connect a pigtail from ground to the fixture box, and let the red wire pass through uninterupted?

I think you say you now have: switch1/switch2/fixture
If that's the case, you should be able to determine which wires from switch 2 are being used at the existing fixture and connect to the same ones for the new fixture.

Yes. I have located the white, black and ground wires in the 3-wire+ground cable coming from switch 2 to the existing fixture. I will connect spliced leads from the white and black wires to the new fixture, and from the ground wire to the new fixture box. Thanks, Dave

Think that I goofed! The power comes to switch 1, but the only 3 wire+ground cable that I have access to is also at switch 1 (not switch 2 as I thought earlier). I made the connections to the wires from switch 1, but now switch 1 turns both lights off and on, unless I turn them off at switch 2. Then, switch 1 turns the new fixture on and the existing fixture off. What can I do to correct the wiring when my only available access is to wires from switch 1? Now, I really need help!

Switch 1 and Switch 2 are "side by side" in the circuit. Neither fixture should be connected "between" them electrically.

I believe you've taken one connection for the new light from the wrong side of switch 1. Take it from the common.

Thanks. Does it make any difference which of the connection leads I reverse? From switch 1 I have red, black and white (+ground) coming out. Originally, I connected the black and white leads to the black and white fixture inputs, and let the red pass to switch 2, uninterrupted. Should I instead connect the red and white leads or the red and black leads to the fixture? Then, does the remaining lead (black or white) connect to the red lead that continues to switch 2? Again, your help is greatly appreciated. Dave

Best and easiest thing to do is to connect to the wires from the existing fixture directly to the new one - if that's possible.
If not...
If I read you right, there is a 2wire to switch 1, a 3wire from switch 1 to switch 2, and a 2wire from switch 2 to the existing fixture. Is this correct? If so, you should not be connecting any of the wires from the 3wire to the new fixture. That will result in "mixed-up" operation.
Whichever switch has the wire going from it to the existing fixture is the one you gotta get to the new fixture.

Another way to think of it is that both fixtures must be on the same "side" of the switches. And neither may be "between" the two switches. I'll try to illustrate below.

0--F1---Sw2----Sw1---0

... F2

The two fixtures must be wired in parallel rather than in series relative to each other.

OK. I'm clear now. My existing fixture is now at the "end of the run", with the 3-wire between switches. The result won't be as pretty, since I have to either fish wire or run 2-wire cable through an exterior channel, but I will connect directly to the 2-wires at the existing fixture. Thanks for your patience, and helpful guidance. Dave
