If you have cruise, you should be wired for steering wheel radio controls (from the steering column to the radio). You can confirm pretty easily.
1. Disconnect your neg. battery terminal and wait at least 5 minutes, making absolutely sure the reserve airbag power has discharged.
2. Put your steering wheel in the lowest position to give yourself some room.
3. Remove the upper steering wheel shroud. It's the top plastic piece right behind your wheel. It takes a little muscle, so just apply even pressure to both sides and pull it up, sliding it out. You'll see the reverse side of the SIR coil, which is the bigger plug in the middle.
4. The 2 wires you're looking for are Dark Blue and White/Black.
If you see them, you're good to go. You will, however, need the steering wheel harness/switch with the audio control plug. You could probably order one for pretty cheap and just install it in your current wheel. As to your earlier question, there is just one plug from the steering wheel to the SIR coil.
Please review safety instructions before doing any steering wheel work.
