V1 Engine to body connector info

[bradr]

I could never find any info on the forums about the interconnect between the engine and body harness. All the "Non-GM" wiring diagrams only show a high level diagram, and not any of the intermediate interconnects. Some cars have a 14 pin and some a 16 pin connector (my 2010 SS/TC). Below is the info from my car.

Please note, Delphi connectors with letter designations for the pins do not use "I", "O" or "Q" as these might be confused with the numbers "0" and "1". Two corners will be marked with letters for reference. In the case of this 16 pin connector, "A" and "H" are marked. From the mating side of the connector, they are numbered left to right, top to bottom.

Interconnect A	PCM X2 Pin 7	Gray/White	HO2 (2)
Interconnect B	BODY HARNESS	Brown/White	MIL Lamp
Interconnect C	PCM X2 Pin 46	Dk Green	Fan 1 relay control
Interconnect D	BODY HARNESS	Tan	Boost Signal Output
Interconnect E	PCM X2 Pin 33	Gray	AC Pressure 5v Ref
Interconnect F	PCM X2 Pin 11	Tan	AC Pressure 0v Ref
Interconnect G	PCM X2 Pin 39	Orange/Black	AC Pressure Signal
Interconnect H	PCM X2 Pin 1|2|4	Black/White	Ground
Interconnect J	BODY HARNESS	Lt Green	Reverse Light Output
Interconnect K	PCM X2 Pin 50	Lt Blue	IAT Signal
Interconnect L	PCM X2 Pin 22	Tan	IAT 0v Ref
Interconnect M	PCM X2 Pin 40	Violet	VSS Low
Interconnect N	PCM X2 Pin 53	Yellow	VSS High
Interconnect P	PCM X2 Pin 23	Tan/White	HO2 (2)
Interconnect R	PCM X2 Pin 38	Violet	HO2 (2)
Interconnect S	PCM X2 Pin 13	Yellow	MAF Signal

Brad, thanks for this information. I am sure it will come in handy at some point for myself and probably anyone else with a TC.

I think the reason you can't find any information on the forum is because it's about the only connector in the entire build process that doesn't get something cut out of it.

Still very good information to know for troubleshooting things like reverse lights, MIL, etc.

Or extending the harness when you move your fusebox to some place other than in the stock location over the transmission.

I will be removing the wiring for the Air Conditioning which is 3 wires as well as the 3 wires for the downstream O2 sensor. I guess in most cases these will be removed from the engine harness, but left in the main harness as they dont cause any issues being left in place.
