my last Taurus cam with Sirius, this was in 02. i don't think you can splice into a satellite wire & you would be better served to NOT rip or pry off the factory face plate or cut into any wires. The Sirius on my Taurus came in a separate apparatus, you can get adapters for any and everything. radioshack & crutchfield.com sell adapters that will fit the Sirius interface. you may even be able to get a sirius reciever off ebay.
& Yes, Tuarus' come pre-wired for Sirius
Actually i am in the process of routing around for harness' for my current taurus and i found a bounty of them @ crutchfield.com check it out before you do anything that will compromise your car's warranty
