Just installed and hid all the wiring for my Sirius sat radio. I always forget to turn off the satelite radio. Can I just hook it up to the power on my radio? If so, does anyone have any info on hat wires etc?
You could do that. Just find out which wire in the wire harness is not the constant power. OR hardwire it in the fuse box to a fuse that turns on and off with the key, I did that with my radar detector.
well im sure you can connect it to a power source that the truck uses and when u turn off the truck it shut down but i wouldnt know how..go ask your local radioshack or gadget store..look on google too lol

Run the wire from the Sirius unit to the back of your radio in the dash. Cut the lighter end off and use two 3M Scotch Clips and tap the power and ground at the back of your radio. On and off with the key!
What you would be looking to do is connect your Sirius power to you trucks ACC/Ignition wire on the radio harness.
The 12v/battery(green/purple) is the always on, this will supply constant power to your radio, this is what keeps your memory stored when you turn off the engine. You will not be using this.
The ACC/Ignition(pink/black or lt. green/yellow) is what turns your radio on, when you turn your key to either the accessory or to the run position this is supplied with 12v.
For what you are trying to do, which is have the Sirius unit turn on and off with the truck you will need to use the (pink/black or lt. green/yellow)
Also make sure you have a good ground, I recommend grounding to the radio itself and not the harness.
For the connection to the wire you will want to splice it in, I recommend against using t-taps or any other type of quick connect, they prove unreliable over time. What I recommend is taking a razor blade and carefully shaving about 1/2 inch of insulation from the ACC wire, careful because the wire is thin(but not easily cut by a razorblade). Next from the wire for the Sirius strip about 3/4 inch of insulation off. Wrap this around the exposed portion of wire from the factory harness. Wrap in about 1 inch of electrical tape. Also make sure that you add some around the insulated portions of the ACC wire and the Sirius wire to keep them together, this will act as a strain relief. Throw a zip tie over the point where you wrapped the wire together.
Normally I would solder, but I left that out of this tutorial.
And as a final note, if you end up blowing a fuse, its not going to be the one for the radio its the ACC/Radio/IGN or something along those lines.

CAUTION CHECK YOU RADIO VOLTAGE FIRST THING. I spent most of the day trying to hardwire my aftermarket Sirius unit form Bestbuy. Finally cut off the plug and connected to fuse #38 but the unit would not turn on. Checked the lighter plug-in and discovered that it was 12 volt in and 5.4 out. Luckly, I did not fry my radio.. For now i am back to the "plug in" method and having to turn off the Sirius manually.
Probably the simplest method would be connect an lighter socket to # 38 and then plug into that keeping all the wires under the dash.
Any other suggestions????
Just go get the cig lighter female end and tap it into the wires behind the dash you want to use. I bought one of the 2 in 1 cig lighter adapters with about 8 inches of wire on each one. Cut one off and tap them into the 12V and ground. Then plug the Sirius 12 volt adapter into this. I do this all the time. Easiest and best way to do it. I wrap a little tape around the adapter to make sure it stays together behind the dash
