I just installed two aftermarket tweeters to my radio-9. Your second pic appears to be the tweeter connector (---two wires, a black and yellow colored plastic MXG connector--found on both driver and passenger side, although the wire colors are different).
Your first pic (...driver's side, I presume?) appears to be a different style connector, and more than two wires, if I'm seeing the photo properly. If that's the case, it isn't a tweeter connector.
The passenger tweeter wire is taped to the loom directly under the rear of the glove box and is easily accessable. The driver's side tweeter connector is taped to the loom above and to the rear of the fuse box. Drop the fuse box and you can see it dangling from the loom.
