The X431 tool lists a 16 pin and a 9 pin DLC for communications. The 16Pin connector (OBDII) I have found. The 9 pin connector I can not seem to locate. The tool instructs a Subaru-9, which I have. Has any one tried to locate and use the 9 pin connector? If so can a location be provided? My service information shows 7 connectors. Of them, I can only find 3.
