I have a 1999 C2500 454 Suburban.
The "Service Engine Soon" light has lit up. I am hoping someone knows which pins need to be jumpered on the diagnostics plug to read the code. The plug is attached to the dashboard under the steering wheel. It doesn't look like other diag plugs that I have seen on some tech websites...it does NOT have the top right, 2 pins (A & B). There is only about 8 pins and they are all spread out across both the top and bottom rows.
I think it is OBD-II
Am I looking at the wrong connector?
Thanks for any info,
Jon
The following link is what the connector does NOT look like:
