V1 C7 (D-GN) class 2 serial wire location

[PHENDERSON]

Hi everyone. I'm trying to figure out where the dark green wire that is to he labeled "C7 Class 2 Serial" originates from on the body control side. I know the other side is from the OBD2 port connector.

I somehow missed this one when labeling the wires and discovered I missed it when labeling the dash wires. I need to know where it originates from so I can pull the pin out and add the wire back to the harness.

Thanks in advance!

I'm trying to find my notes because I missed labeling this one as well and I eventually found it.

I'm not sure what year or trim your donor is, but this is what I have noted and can recall from doing my 2007 SS/SC last month.

The C7 Class 2 Serial wire is the C7 pin on the 'C201 I/P Harness to the Body Harness' connector and is circuit 1049 according to the wiring diagram. This dark green wire ran to Pin 2 on the 'DLC' (OBDII) connector and connects to the wire coming out of Pin 16 on the 'PCM C1' connector on the fusebox side.

Here are the diagrams I referenced and others can chime in to correct whatever is inaccurate above. I am going off of my notes and memory. I didn't have the wire to label when I was at that spot in the video but it made sense with these diagrams when I went back to fix it.

Mine is a 06 SS/SC and I traced it to the same OBD2 pin so this must be the same for me. Thank you so much!
