First of all, thanks for the reply!

The part number I listed earlier is switch controls for both sides of the steering wheel:
Toyota Name: 84250A STEERING PAD SWITCH ASSY.
Toyota Part #: 84250-52010-C0

Note: The last two digits of the part number indicate the colour:
B0 = Silver
C0 = Black

Left side controls = Volume Up/Down, Mode and Seek Up/Down
Ride side controls = Push to Talk, Answer Phone, Hang Up phone

- Is there a part that only has the PTT/Answer/Hang Up assembly? I already have the smaller steering cover + vol. controls, and by a quick google search, I have found that the part costs approx. $130 USD? Is that reasonable? (And, where do you source your parts? Local Dealership? Online vendors?)

Also,

The switches will work provided the steering pad cover (air bag) has room for the switches on either side.

If you currently have a narrow steering pad cover (air bag) like the one pictured below then you can add the switches:
Attachment 45022

However, if your steering pad cover (air bag) is wider like the one below then there is no room for the switches:

- Since I already have my vol. controls on the wheel, does that mean the spiral cable is there already for me to plug in the bluetooth control assembly?

Finally, can you please inform me on what wires go from the ASWC to the Bluetooth functions also?

And thank you for the tip re: NOT drilling the steering wheel. Duly noted. :)
