2008 gmc savana 2500 tcm pin diagram

[1958paul]

not sure if this is the right forum or not but have a question. while reworking my harness i found a dark blue wire coming from pin 47 on the connector for the tcm that has been cut and goes nowhere i also have a dark blue wire from pin8 on the same connector that goes to the round plug that goes to the trans. the only pin diagram i found for the tcm connector states that neither of them pins are used. the diagram i found was on a gto forum so not sure if the gmc tcms where wired differently. where should the cut wire go or is it not needed? when i got the van the trans. was already removed. thanks
