I was under the truck and found this 4 pin cable below, hanging by the accelerator pedal not connected to anything, with the tags marked 762A, 762B, 762C, 762D:

I searched all the manuals and the only mention I could find was a 762A in the 4L80E Troubleshooting Supplement, but it looks like it is a different connector:

Does anyone know what the connector it is for and where it should be connected? Maybe it's just a test cable?

On the schematic, that plug gets hooked to: FUEL PRESS X-DCR
Thank you for looking it up, I don't have that schematic, is it in one of the manuals?
What and where would this (what I think maybe it means) FUEL PRESSURE X-DCR?
DCR = Diesel Common Rail? And X for Extended/ External? I have the 6.5L Turbo, which I don't think it's a common rail?

And where is the other end connected to? Sorry if I am not up to speed on all the terminology, I am still getting my mind around the truck :)

X-DCR is transducer and it's the useless sensor that usually sticks up out of the top of the fuel filter which sends fuel pressure to the diagnostic plug in device called the STE-ICE which is Simplified Test Equipment-Internal Combustion Engine.

Thank you! I know what you are talking about, it's a non-issue now that I understand, I appreciate it!
