Ron you should have gotten a bulkhead connector and two GPS cables generally a 10' and a 15'. This connector is in a plastic sack with other various small pieces such as adhesive clamps etc. As AL has mentioned this can be used to created a permanent connection through the cab. On my 9500 I used the 15' only in the combine and the 10' in the tractor. In this way I never move the GPS cables.
Extra cables are availabe for other installations.
