Need help bypassing back-left door sensor!

So I've got a ton of playstation 2 slims models 75000/77000/79000 with broken back-left door sensors. On the 70000 model it's easy to close the circuit to always be on by bridging the top two solder points with wire. Then, the front door sensor takes care of everything. However, on these models it doesn't seem to do anything and I'm a little stumped. Possibly a pinout would be enough for me to figure it out. If anyone has any input it would be greatly appreciated, thank you.
