Does anyone know exactly where, on the Drivers side head, ground wire G112 is attached.....I need to check to make sure its tight. But I'll just be reaching back there blind with my hand.

Its an 02 sensor related ground wire coming off the PCM harness.

Thats cool.

I'm needing to follow both FRONT 02 sensor wires up from the sensors, all the way back to the PCM. I need to check for damaged wires or corrosion at any of the splices.

Thanks.
