Hey !
Thanks for this nice DIY project.
I have some experience in basic electronics, and I work in IT so I have some programming experience too, so that could be useful.
I will very likely give a shot to your tutorial for the DIY reader on the connector behind the head unit.
One of my main interest, in addition to the fun of having a nice DIY project like that, is to try to implement a Door Autolock functionality, which we know is already doable due to projects like the
Trac-box, or some ODB devices that require to connect on the OBD port.
I don't want to pay $200+ for the Door Autolock functionality, and I my OBD port is already taken by my OBDLink MX+, so I will try to find a way to achieve a similar result using the connector behind the head unit.
