obd2 connector wiring
Hello everyone,
I can't seem to find where the obd2 port wires go to. I know the port connector is normally located under the dash, but where does it go to from there to retrieve the data from the PCM? 05 ls 6.0 from chevy Silverado 2500hd Thank you, double |

Pin 58 - Dk Green - Serial Data - This is the Class 2 Serial Data wire that goes to the diagnostic port (OBD2) pin 2.
the link is to the PINOUTS for your year. http://www.lt1swap.com/2004vortec_pcm.htm

I got it hooked up to test out the hp turner software and for 3 hours I couldn't connect to the PCM. I was so heated and aggravated. Then I had a Macgyver moment as I was holding the I.V PCM wire. I touched the orange wires and all of a sudden it lived. One. Fricking. Wire. |
