two dimmers for 5 recess lights

I am trying to replact to light switches with two dimmer switches. The the dimmers are 3 way switches with a green wire, a black wire, and two red wires. I have the romex with white, black ,and cooper for my lead. I have the coax with a black, a white, ared, and a cooper going to the light and running between switches. I really don't know how to connect thses two switches to be able to control the lights from either switch. Any help is appreciated.

Dspr147, Just so you know, you can not put 2 three way dimmers to control the same set of lites, one has to be a three way switch. If your lead comes into "box 1", put the 2 white wires (one from your feed, the other white is coming from you 14-3 (or 12-3) under one wire nut. Take the black from your feed (lead as you call it) and wrap it under the black (common) screw. Now take the black from your 14-3 and wrap it around one of the other 2 screws (the 2 screws will be the same color, it doesn't matter which one you use). Now take the red wire and put that under the other (now the only one empty) screw. At the other end, put the black from your 14-3 under one screw (not the black=-or common screw) Put the red wire under the other screw( again-not the black,common, screw). You should now have 14 (or12) 2 wire left. Wire nut the two white wires together and put the black that goes to your lites under the black-common-screw. IN each box tie all your grounds together. If it is a metal box pigtail a wire to bond the box. Also, include a pigtail to ground the switch or dimmer regardless if the box is plastic or metal.
*****Before you do any of this, make a sketch or take a picture or label the wires so you know where they went!!!*** This is VERY important because assumptions were made when I read your post. If I mis read anything or you mis typed, we can figure out what you had hooked up.

 

thanks for the help.
