How to Open Meter Panel and identify Parking Break cord and Reverse light cord in Toyota Solara 2000 ?

I have Toyota Solara 2000 and Last week I found a very good deal on a Clarion NX500 Multimedia In-Dash Radio with Navigation, DVD player, iPod, Bluetooth and Rear view camera. I also purchased rear view camera and "Clarion bypass CR2" to bypass the video lockout feature. Since I went over my budget I decided to install it myself. I had an adventurous weekend and I could successfully install my head unit except I could not find Parking Break cord and Reverse light cord. So the bypass and the rear view camera is still pending. I shall appreciate if someone could guide me to a right path. Thanks!
