I need to locate an "always hot" power source for my new XM. Everything else is a piece of cake, but the unit came with about three feet of wire with an inline fuse, built in to the main XM harness. Instructions say to connect this lead "to a terminal that is always supplied with power regardless of key position". Anyone know of a hot wire within three feet of the Head Unit that qualifies? Thanks in advance!

Never mind, Got it done. The yellow wire in the main radio harness is constant hot.

LOL.. I just love it when I or anyone else answers their own questions!

Thanks for the tip, though. I'm sure someone else will benefit.

RedDragons, repeat that in its own thread under the name: Stock Wiring Color Coding
That would make a great sticky, so I'll pin it up under this section: http://newscionxb.com/audio_electronics-b12.0/
