XM Onyx Install..FM direct adapter

[sam60]

I need to hook up my XM radio in a 99 Continental. I have the adapter that goes inline on the antenna cable to get better reception.

Where is the antenna located? I had to hook it up in the truck of my previous Taurus. Did some search with no luck, XM part FMDA25.

Thanks

From the 1999 Ford Service Manual for the 99 Continental:

The antenna is concealed on the inside of the rear window glass. The AM antenna consists of the rear window defroster grid and the FM antenna is the conductive tracing above the rear window defroster grid.

The radio antenna uses an antenna isolator module mounted under the rear package tray trim panel to separate the AM signals, FM signals, and rear defroster power.

The radio antenna uses a two piece coaxial cable to connect the radio chassis to the antenna isolator module. The front antenna lead in cable is connected to the radio chassis and has an in line connector at the bottom right side of the instrument panel. The rear antenna cable connects at the bottom right side of the instrument panel and runs along the rocker panel within the main body wiring harness. It separates from the harness at the quarter panel and runs behind the rear seat and up to the package tray where it connects to the antenna isolator module. A third coaxial cable connects the FM antenna to the antenna isolator module along the right side of the rear window.

You probably didn't find the isolator because it is under the rear tray shelf, but above the metal, you have to remove the seat cushion and back and third tail light to get the package shelf out to get to it. You can't get to it from the trunk, just the passenger compartment after removing the seat to remove the package tray.
