So, after doing some more research, I've found that the BUSLink interface is the same as the USA-Spec unit, just with a different sticker on top. The cable that is the issue actually has "USA-Spec" written on it. So here is the issue:
The cable looks like this:

I believe the pinout is the following:
1 +12v out
2 mute
3 S.GND
4 L+ in
5 R+ in
6 +12V ACC
7 TXT
8 TX+
9 TX-
10 GND
11 L- in
12 R- in
This is apparently is the way the radio on 98-2002 Camry's is.
My radio has the following type of connector:
_____ _____
| 1 2 | . | 3 4 |
|
5 6 7 8 9 10|
but maybe this image is the one I need:

in which case I guess I need to try and find this adapter.
For further clarification, my stereo has a model number of 86120-AA160 or on the front of the radio it says 16860.
Thanks,
Jon
