Since I'm new to this list I will post here. I need to get behind the stock radio to connect up power and ground for the wifes XM radio, and am not sure just where to start and rather experiment on the truck i will ask for a little guidence before I start. Where can i find the informantion?

 

Welcome to the site.

Give us a little info on your truck.
Year, etc.

Moving this to Accessories forum.

 

I'd just pickup a wiring harness from just about any stereo shop. They are relatively cheap and you just plug and play. (You'll need to solder and tape the wiring harness to your XM radio wiring harness, then it plugs directly into the vehicles stock wiring)
That way you can easily replace the stock radio if you want to trade or whatever...

You can also just strip the wires off the stock harness and solder into it. But this way is much faster.
