You need to re read this thread from post number one. I can't see how you are having an Issue But let me try to explain It again
1. Two ways to tap in. At the small (not big) connector on the back of your radio. Or the xm receiver in the left rear of the trunk.
2. Three wires you will tap into. Note there are ONLY the 3 you need at the back of the radio connector.
3. There are 4 wires from your set of rcas left has 2. Right has 2. NOTE: Ignore the foil or bare wire if your rcas have them they do nothing for us at the moment.
4. Every set of rcas is constructed different I'm sure. My set was made by stinger. I opted for a short set of 3ft since I am using the radio connector instead of the xm receiver. I simply cut the ends off ONE side. Left was yellow for positive. And right had a red for positive. Both sides have white they are the common ground for the audio. You hook BOTH white wires together and then attach them to the black/white wIre. Hook your left to positive wire(mine was yellow) to brown/whIte. and your right positive (mine was red) to green/white
4. Now your one end of rcas should be attached the car. The other In your hand with the left and right rcas untouched.
5. I personally used barrel connectors (female on both ends) to attach (see pic) these 6ft male rcas to 3.5mm headphone jack.
Your other option would be just get a female rca ends to 3.5mm jack.
That's it.
