You either have a pw0 or a pr3 ecu. both of those should apply to that diagram he just posted. If you need more details, do a search on google for "pr3 pinout" or "pw0 wiring pinout" or something along that line. I did a search and got more than one version of pinouts for the pr3. I think there's an obd0 and an obd1 pr3(i hear, not sure), so that could be why. But, good luck.
