Thanks Mark.
After further inspection, I found out that my problem is the opposite of what I thought, it is that the stop light is always on, and it seems the problem is from the rear break switch, that is why disconnecting the front break switch's connectors and shorting them together did not change the status of the break light. I found this out when I removed the turn signal / stoplight fuse.
Now I need some time off work to disassemble the fiber on the side to check the switch.
