Also, after you went behind the glove box, where did the antenna come out? Did it come out under the carpet? On top of the carpet?
According to your diagram you need to remove the front and rear door scuff plates...(pull up and they pop out).
The center pillar garnish can be removed or just popped out towards the bottom. I didn't completely remove the center pillar garnish, just popped it out towards the bottom. Either way will work.
When you have your stereo removed look at the dashboard behind it towards the right and you will see a small opening through to the carpet...you might need a flashlight if your in a low light situation.
The reason I used a coat hanger and taped the wires to it is that Lexus tolerances are so tight due to the fact that is a high quality auto, its hard to stick your hand anywhere to run wires. You can use the coat hanger to fish the wire through. Wrap the coat hanger with electrical tape in case it makes contact with any connectors so it wont short anything.
The antenna wire will come out on top of the carpet. There is a panel under the glove box that will need to be removed, it pops out also.
I attached a pic that you can look. I was going to post it with the other pics but ran out of space.
The pic shows the Pioneer head unit. You can see the wires behind it. If you look to your right you will see wires hanging under the glove box....that's where your antenna cable needs to come out.
