I have looked.. I do have the ecu pinout but I was looking to see if anybody had a picture of every plug with identification (SOHC obd2). This would save me a lot of time...

 

If your looking for an obvious difference, I believe the primary o2 sensor (air fuel ratio) would be a dead give away.

 

I'm looking for a picture with all the sensor plugs. I could trace every wire from ecu, but I was looking for the easy button. Merging h22 harness with d16 so some sensors are different and some wire colors are different.
