Hi there, 2whitlocks,
I saw your post this morning and wanted to follow up with you. First, I just wanted to be certain that you had the correct manual. You'll need the TracVision L3/S3 owner's manual. Unfortunately, the satelliteguys bulletin board doesn't seem to be letting me include URLs in my post so I'm not able to link you directly to it. Instead, the easiest way to find the right manual is to visit KVH.com, click the "Support" tab followed by the "Product Support Library" link. From here, you can choose "Manuals" and then download the correct owner's manual. The instructions to make the service change are available starting on page 2-17.
If you have any questions or need assistance, I invite you to contact one of our factory-trained technicians nationwide our our technical support team with a searchable dealer database and multiple tech support contact options also available when you visit the KVH web site and click the "Support" tab.
Hope this helps and that you enjoy your KVH TracVision.
