I have a pinout. I have backups of delivery speedometers. A programmed speedometer has a software lock. Back then I broke two 6WBs on my project. I won't be sharing the pinout any time soon

You need to identify the MCU type
Search for it in vvdi MCUs
If you are lucky it should be there
Trace the points from mcu legs to nearest pcb soldering points. (If its non bga)
Try to read.
If its ok to handle losses you are good to go, if not, don’t touch it smile
I understand why some people don’t share these schemes, because it really takes alot of time and effort.
Sometime you work alot and u don’t reach anything, or end up with non profitable or non interesting findings.

What do you mean with software lock?
Can you replace 35160 if you restore backup of a new 6wb?
