3 way switch help

I am upgrading an office trailer and have come across the following. 14-2 leads from the panel up to 3 tubed light fixtures, from the lights, 14-3 comes down the wall to where there was a single switch. I have removed the switch and have now installed two 3 way switches at either end of the trailer and ran 14-3 from the original switch box to each of the new switches. My problem is, I can't figure out the right combination to make it work. Any help would be greatly appreciated.

Here's the wiring you need:

You have an extra jbox compared to the drawing, but as long as you get everything hooked up as shown it will work.

You also have an extra wire in the cable from the fixture to the switches. You may have to open the fixture to see which two wires in that cable are the switch loop.

The cable between the light and switch is the switch loop. What wire do you mean? Do you mean the white from light to switch? It is capped off. It is there only to provide the code required neutral.

Here's a different diagram. the reflects what you have.

Technically to fully meet code you would need a neutral in both switch boxes so you would need a four conductor cable between the switches. Check with your AHJ.
