J'ai encore trouvé un peu de renseignements sur la connectique sur un autre forum que je citerai pas cette fois et que je résume:

The Spyder is a highly computerized vehicle – the anti-lock brakes and engine management system designed by Bosch work together to make an inherently unstable geometry smooth and stable.
This system is not OBD-II compliant. It is a totally proprietary protocol.
The Spyder has a 6 pin diagnostic connector under the front hood. The schematics tell me this connector carries a differential CAN pair, a K-line signal, chassis ground, and two +12V accessory power lines fused at 10A each (they are not 10A dedicated to the diagnostic connector, 10A shared on a bus with various other parts).
I built a cable that connected the Spyder diagnostic cable to my OBDPros bluetooth adapter that uses an ELM327 compatible chipset to extract OBD-II data. I used the Torque software on my Android phone to scan the bus but it recognized no flavor of OBDII protocol it understood.
The AOA board has an embedded FTDI 232R

the "K-Line" is an alternative underlying physical layer for OBD via the KWP2000 protocol (ISO-9141) providing bidirectional serial communication with a data rate up 10.4 kilobaud. The CAN line (ISO-11898) is significantly faster with data rates of up to 1 Mbit/s.

Voila, j'espère avoir fait un peu avancer ce post
