Hondata

While doing troubleshooting to my p28 board, i accidentally shorted the 5V and 12V together causing the S300 not functioning. There is no more LED light on the S300 indicating it is alive and I've tried to swap the S300 to another confirme working board and it is also not working. Do hondata provide...

pleaseeeeeeee.....

I've found 5 pin CN2 to be somewhere up left of the pics. Can I solder the shortest ribbon cable and follow the sequence 1-4 and connect it to Hondata?

Unfortunately I'm not in US. How about P30 ECU? I know where the eprom pin goes. But anyone know where the 4 pin goes????

oh Gods of Hondata.
Case modification aside.
Please help me and give me some hint on the connection part. Attached is the pics of the P72 please feel free to draw on it and comment. Thank you.
