Zr2 newbie

[Battlebornzr2]

Hi all, just picked up my zr2 bison hd yesterday, my 22 at4 3500 ate it's trans and gm bought it back..
So far this is better.
Quick question...what are all the new wire harnesses in bags under my back seats?

No, it's not that. 3 diffrent wire harnesses and a relay block with mounting hardware.
My at4 came with them 2 , never figured out what their for.

Hmmm...this truck didn't come with the factory winch, eventhough I ordered it.
Thanks for the imput when I get a chance I'll research the part numbers.

The fuse block and harness with the heat shield are for the Upfitter switches and the harness in the bag is for the plow prep package.

That makes sense.
My 22 at4 3500 had them too.
Thanks for the help.
