Ah, I see. I had read something similar about doing the exact same thing, but I was a little skeptical because when it comes to playing with wiring and soldering, that is not my strong suit. Ray actually offers for a bit more money ($95 I believe) a 3 foot cord the plugs into the back of the actual head unit instead of the XM Receiver in the truck. It does exactly the same thing, but it bypasses the signal at the radio so you don't have to run the cord through the car like I did. With the 11 foot cable he gave, I had about a foot of slack or so to play with.
