Sirius radio upgrade
 

just purchased the sirius satellite upgrade kit for my o5 E.B. explorer. It has the audiophile 6 disc cd changer WITH the sat button. Kit did not include a harness to connect the downlink processor to the radio. Is there a connector already wired into the vehicle some where. An optional harness is available, but I have been told that the harness is prewired into the E.B. and limited models since the 6cd system is standard.
I don't want to tear my new vehicle apart if I don't have to.
Thanks
