Need help putting an additional fixure on a 3 way switch

Hi, I'm new to the forum so please bare with me. In my kitchen I have a 3-way switch set-up that controls (1) small light. I am trying to install an additional light by taking power from the existing light. There are three sets of wires going to the electrical box of the existing light.

3 Wire - Red, White, Black, Ground
2 Wire - Black, White, Ground
2 Wire - Black, White, Ground


The existing light fixture is wired as follows:

Black wire from fixture to (3) neutral (white) wires from box
The other Black wire from fixture to a Red wire from box
Ground to ground from box

All the other Black wires are coming out of the box are tied together.

I was told to tap into the existing light. I fished wire from my new location back to existing light and wired them as follows:

Black to existing Black Wires
White to existing White Wires
Ground to Existing Ground Wires

The light works, but it will stay on and the 3-way switch will not control the new fixture...so it just stays on, but the existing fixture works fine off the 3-way switch.

Was I supposed to run the Black Wire from the new fixture and tie it into the Red and Black wire from the existing box?

I hope I have been pretty clear. I'm hoping I just need switch the Black wire from the new fixture that is tied in with all the other black wires to the Black and Red hook up.

Anyway...thanks in advance for your help.

Connect the black wire to the red wire and the black wire of the other fixture.
So jbfan you're saying to do what I quoted in my last couple paragraphs:

"Was I supposed to run the Black Wire from the new fixture and tie it into the Red and Black wire from the existing box??

"I hope I have been pretty clear. I'm hoping I just need switch the Black wire from the new fixture that is tied in with all the other black wires to the Black and Red hook up."
It is very simple. Connect the two wires for the new fixture to the same place as the two wires from your existing fixture. DO NOT change any of the other wires in the box. In your case you should be connecting to the white bundle and the red black bundle.

Connect all the grounds together.

Yep .

And take digital photos of everything before you disconnect any wiring . It is also a good idea for a newbie to use something like masking tape and a sharpie and label each wire as to where it goes and what it does ( if you know ) .

God bless
