In the middle of doing my wiring harness and ran into one problem that hopefully someone can clear up really quick.

I'm following the instructions on LT1swap.com, and have everything taken out of the PCM connectors, but found that the grey low reference wire on my ECT plug was cut. I'm trying to figure out where it goes. The Alldata diagram on LT1swap is saying Pin 80 on the C2 connector, but the pinout says that that pin is for "HO2S Heater Low Reference (w/isolated grounded sensors (2001-02 6.0L Only)".

The harness is 2002 Chev Silverado 4WD 5.3/4l60e with all emmissions and transmission fuctions deleted.

Thanks for any help!

Pin 80 of the C2 connector?

Where did the grey wire originally go?

I based the engine side off this diagram for the 411 computer, my original harness was a 24 DBW that I depinned and repinned for 99-03 style

The gray wire appears to go to pin 41 but I can't tell which connector it is, because of this POS schematic I'm looking at. It's the same connector with the injector signal wires going to it.
