on the 88-91 OBD0 cars with PM5, PM6, etc. the atmospheric Pressure Sensor (PA) was located under the dash on the passenger side kick panel - on the 92-95 OBD1 cars with P06, etc., the PA sensor is inside the ECU
PM5 also has pins for a device called an "ELD Unit" which I can't find on the P06 either. Did they do away with the "ELD Unit" (whatever the hell that is) on the P06/PM6?
the ELD or Electric Load Detector is located in the Main underhood fuse box on both the OBD0 and OBD1 cars - on OBD0 ECU the pinout is at B19 and on OBD1 ECU it is at pin D10
On the OBD0 harness (PM5) I also show a "Ignition Timing Adjust Connector" that uses the Grn/Wht supply voltage wire for the TPS, Intake Temp, Coolant Temp, and does something before going back into the ECU. What does that thing do? I can't find anything similar on my OBD1 (P06) harness.
green/white wire are ground wires - the connector is under the dash on the passenger side behind the kick panel on the 92-95 cars - its function is to disable the ECUs ability to adjust the timing while you are manually setting the ignition timing
making your own jumper for OBD0 to OBD1 is not all that simple - the OBD0 ECU plugs will not plug into the OBD1 ECU - you will need the plugs from inside of the OBD0 ECU in order to plug the cabin harness into it and you will need the plugs from an OBD1 cabin harness so that you can plug them into the ECU - you then wire between the 2 sets of plugs
