So after reading around i decided this had to be possible so bare with me and ill show you.If you dont use xm or dont subscribe this will work perfect for anyone looking to add an input.
things needed: 3.5mm headphone cord of choice
elcectrically tape/heat shrink
optional: head phone jack
ok well i started by identifying the wires ill be working with. xm reciever is located in the trunk on the left side behind the carpet
i pulled the reciever out and there is one pin connector. pull it and you will be using three of the wires.
The three wire you will cut will be pin 2 left audio+, pin 3 right audio +,and pin 10 audio - (common)
After this i strated to make my cable. i used an walmart brand rca and cut a rca to 3.5mm headphone jack and spliced them together and soilder it all together.
After i have made my cable i begain to connect my wire to the inputs on the xm harness. you will want to cut the wire and hook the negatives to the black/white, and the right to the brown/white, left to geen/white. soilder together when done.
you can test to see if its working at this point. just make sure you plug the xm recievier back in. it needs powed for this to work.
after this you can run it accordinly. I ran mine between the carpet under the center temporarly till i get a jack.
To make it work all you have to do is switch to xm and listen up.
Thanks for looking everyone.
