I have a 95 Pontiac and I wanted to dump the error codes on it to find out why the service light was on.
I went to the connector under the dash, and you're supposed to be able to ground the 'Diag' pin at "B" to ground at "A" and it kicks the computer into a diag dump mode.
But I don't have a connector pin at "B"
Yep, it's the 6x2 connector. Yep, the vin codes all match correctly to let me know it's engine "M" for that year and it should have the
6x2 connector. But there's a TOTAL of 3 wires connected to the connector.A black wire at "A", which I'm assuming is ground A tan (or light colored) wire at "M" A green (I think) wire at "I"
In all the documentation I can find, there were NEVER any wires in the 'lower row' in slots "H" to "L".
So... What gives? Any ideas? Ground should be fairly easy to trace out, but what are the other two wires, and why are then in the slots I found them at?
