Are you wanting to make your own cable for the GPS antenna? Whatever you are trying to do, you'll save money simply buying an Eclipse GPS antenna. Works just as well. The Kenwood GPS antennas are the same too, just more expensive.
I posted the info under another topic here:
Where 2 buy GPS antennas?
If you are wanting to build your own and find the part number for the connector & pins for the GPS antenna, let us all know. I've been looking for that as well...
