Gameboy Advance CPU Pinout

Hi there,

I'm new to modding and have come across an issue on my GBA board. The TP2 test point has lifted and caused the select button to become non-functional.
My aim is to fix it with a bridge wire, but instead of scraping traces I would like to find what pin exactly this trace for the select button connects to and solder there directly. Does anyone know the pin out or have a well labelled schematic?

Thank you for any help you can provide.

TP2 test pad goes directly to the CPU ( 3rd pin up on the left side).

Dont know if the info is still helpfull with how long ago your post was, but I havent been on this site in years and didnt see any other replys.
