[Gmecm] DLC question

[Steve Ravet]

The schematics for my truck ('02 K1500) show 4 wires to the DLC:

pin 2:  class2 data
pin 4:  gnd
pin 5:  gnd
pin 16: Vbatt

But my actual connector has a fifth wire, green, on pin 14.  The OBD2
spec seems to say this is a CAN line, but if CAN were implemented there
would have to be a wire in pin 6 also, and there's not.  Any idea what
this wire might be?

thanks,
--steve
