I don't think I have 2 OBD2 plugs in my car, i have the repair manual and it only points out that one in the center column.
i don't know if this is true but I have a friend that tells me that the ECUs made for the Type-R in those years (as it is a JDM ECU) was made with an obd0,
In other words, it is not compatible with any reader from what i understand.
my ECU number is, if i remember right, 37820-P73-003
