I have an 04 ion redlin with the cd/mp3/xm ready radio, so I figured I would pick up the sirius converter (I already have sirius the subscription in other cars). Here is the issue. The radio has the spot in back to plug in the harness, and then the harness runs down to the sirius unit. There are 2 power wires that need to get 12v, and then there is the mystery harness. It says it is supposed to go to the bus the runs to the back of the radio, but there is no such harness.

see page 11  
there is no factory bus connector, and that makes sense to me… these are xm ready, not xm installed.

someone throw me a bone here
