Thanks for the information......found quite a bit of the 'expandable sleeving' onI used the plastic expandable loom that I put over my wire when I rewired my tail lights. It fit perfectly. I couldn't find the cloth loom so I went to the plastic loom.
here's a link to what it looks like, I seem to remember that I ordered it from another company though. or ebay can't remember

If your not concerned with being factory correct i just used some rubber vacume line over mine. worked great. ran it under water in the sink and slid it on.
