Wiring diagrams for 96/OBD2
Can someone point me to known accurate wiring diagrams for my 1996 OBD2 car? I found some supposed 1997 service manuals that came from what appears to be a Russian source but some stuff in there about torque values and wheel bearing parts was not accurate so I don't feel I can trust the wiring diagrams either. I am working on some interesting projects involving the TCU and ECU for us poor OBD2 folks.

1. I have built a little electronic module that can be clamped onto the ATF temp sensor line to read that sensor directly. It converts the voltage to a temperature and displays it on an LED readout. I want to make sure I tap into the correct lines for the sensor, ground and power. 2. I would like to start thinking about how one would program a standalone EMS to interface to my TCU. 3. I would like to see if there is a way to fool the TCU into doing things a little differently like lock up the Torque Converter in third gear when the stick is in "3". |

Has some service manuals, with some wiring diagrams. I have also attached some things that may be useful. http://www.subaru-svx.net/photos/fil...ye95/12431.PDF |

Obdii tcus are the same as obdi except for barometer in an obdii is external to the ecm. I had a hydra running on an obdii auto. The tcu coded for something that i cannot remember bit it had no effect on performance

Im not 100% sure but i remember they take all the same inputs save for can connection to the engine ecu

Tom,
Did you ever find the 1996/1997 TCU wiring diagrams? I want to make sure the one I have been using is accurate. If it is, the OBD1 and OBD2 TCUs should be interchangeable, aside from size and fit. It looks like the connectors are the same and the pinouts are the same. I am coming back around to an idea of using a modified OBD1 TCU in an OBD2 car, after figuring out how to shoehorn it in there. |

Closed area network was mandatory for all obdii vehicles. This way all modules associated with powertrain can talk to eachother... take one out and the engine ecu will cry about it
