If you have a plug-and-play XM radio like the Delphi or the Roady then don't cut off the cigarette lighter plug and hardwire it into your car. Those models take 6V input and have a converter built in to the cigarette adapter. Sirius radios are all 12V so you won't have that problem.
Also, merely wiring into the same source as the head unit won't make it go on and off with the radio. The head unit has a 12V battery (constant) feed and a 12V accessory (RAP) feed. The power is there even if the radio is off. It will go on and off with the ignition switch as long as you don't use the battery feed.
If you want the satellite radio to go on and off with the radio then you can use the power antenna lead (pink wire at pin 8 of the 10-pin black connector on back of the radio).

If you can't determine which wire originally went to the center pin then you'll need to use a multimeter to determine which wire has continuity to the inside of the satellite radio connector. The outside of the connector is ground and the inside is power.

thank you..I haven't cut it off yet, but on the outside...the one wire has a broken wire line down the entire length of it. how much is a multi meter?

I thought that the stripe meant negative......
I could be wrong...WhiteBird00 knows his stuff.
I prefer color schemes (red for +, brown/black for -)
I guess its a good thing I graduated as a software guy and not a hardware guy.

btw, normally, if i hardwire a Sat radio, i wire it up to an ACC, not 12v. On the S50 (the expensive portable one) DO NOT HOOK IT UP TO ACC, it must be 12v, and the person will have to manually shut it ON/OFF. There is something wrong with the internal design of the S50 that it will fry the internals if connected to ACC. I believe DEI is trying to fix it (at least i was told by the rep) but for now, USE 12v for that one
