Man I don't remember , I will see if I still have the PIN out schematics that shows it .
Just saw it once when helping someone else with this , it did show it was not used and was for ground at Temp .
Blue is probably it , if not used , but some do serve dual purposes .

If you wire it correctly, you can control the fans pretty much any way you want. I have a 2001 Corvette and a 2002 Silverado both running the same operating system. That means I can have the same type of fan control in the Silverado as I do in the Corvette. Obviously, the PCM-to-fan wiring in the truck has to be modified, but once that's done, you'll have the same type of dual fan control as exists in a Corvette, once you reflash the PCM. I'm not sure how other systems display the relevant tables, but in EFILive, if you look under "System" and "Fans" you'll see the control options available. I'm gathering the parts to do a dual electric fan conversion on my Silverado and I'll post the gory details when it's completed.

Man reading this got me confused I thought the e-fans were an easy mod. I got an 06 and was going to buy a nelson harness and use some a flexalite 282?? I think, big dual fan had it on my old suburban. Anyway i was going to get a new tune with the fans turned on, being that its an 06 will the fans work low and high etc without me havign to add extra relays?

That is why I went with the stock fan harness comes with fuses relays and hooks right up to fuse box can't even see it .

Does the factory fan harness come as a separate assembly? I thought it was mixed in with the headlights, etc...?

I think GMpartsdirect.com and I have a couple of more places that have it but can't remember them right off hand .
And yes the harness is part of a forward fog light assembly , so if you don't have fog lights and you want them you get two for the price of one .
