Looking for a schematic diagram on the JDM P30 Auto ECU pinout.

That should help. If you need actual wiring diagrams you'll need to pick up a service manual.

Thanks, I came across this. I'm not sure if my builder can use this since he is making a custom OBD2 to OBD1 harness. I need every wire on where they go on the P30 ECU.

Is this the same as the JDM SIR-G pinout? I have the SIR-G pinout saved on my hard drive.

Its the same as any OBD1 Honda. Some automatic vehicles will have a 4th plug thats not on this pinout, but thats it. Your best bet is to get the factory service manual for whatever the car is and match everything up. Heres an actual pinout with wire colors for OBD1 taken from ff-squad --> http://ff-squad.com/tech/wiring/obd1.ecu-pinout.zip

Thanks I got this file saved on my hard drive for like couple of month. I was not to sure if it was the same pinout from the SIR-G P72 to the P30 ECU.
