The power was turned off and bricked during the ECU write.
I want to restore it, but I can't figure out the connection terminals.

I have the equipment to connect, so if I can just figure out the terminals, I should be fine.

https://nissanecu.miraheze.org/wiki/BootmodePlus the datasheet for the 7055, and a multimeter, you can trace the required pins - they usually end up on testpoints on the PCB
