I am setting up a set K-Wing bars with ergo shifters. For the life of me I can not cram those little grommets into the holes in the bar per the directions of FSA. Has anyone succefully done this with a campy set up?

Well, I figured it out...in case anyone does a search on this in the future here is the skinny on how to get this done:
1. Follow the instructions regarding the grommets that came with the bars to cut along the groove to open them up to accept two pieces of housing.
1. Ignore the rest of the grommet instructions and install them before installing the cable housing.
2. using a zip tie, bend it gently in half and push the bent portion of it into the hole in the grommet so it forms a circle inside the bar.
3. take an old cable and cut the button off the end and fish it through the bars and out the grommet.
4. slide the housing from the levers onto the old cable and through the bars. use hemostat or a vice grip to keep the cable from pulling through the housing when maneuvering them.
5. push the housing through the bar and grommet while pulling the cable to the side to allow the housing to clear the inside edge of the bar/grommet.
6. repeat the entire process another 3 times (once for each piece of housing...duh!!!). When doing the second piece of housing on each side just push the piece already in place to the side to make room for the zip tie.
The zip tie replaces the strip of plastic included with the bars used to catch the housing so you can pull it out. With the grommets in place the length of the hole the housing comes out of is slightly shorter so the plastic strip will not fit...therefore use a ziptie in its place.
Also...it is hard to insert the cables into the body of the levers once they are pulled through the bars...I found it easier and without fear of kinking the housing to insert it into the levers before fishing it through the bars. for the shift cables this will mean you have to run the old cable through the body into the housing and then into the bars before fishing it out the grommet to guide the housing. Because of this step I recommend doing the shift housing first.
This was a total PITA because I had to do everything twice. It was slightly less a PITA the first time around. In the end the bars look good and it was worth it to do the job over to get it done correctly.
