Guess these WIRES!!!??? I'm guessing its something to do with O2 sensors sense i dont have any hooked up and i can see the rear O2s off the harness that goes on tranny.
This harness part is connected to the MAF sensor, and this one has what looks like a heat tape around the plastic. But theres alot of wires??
This is for a 5.3/6.0 Vortec. ( but came from a 6.0 )

yea each o2 sensor has 4 wires. tan, pur/wht, pnk, blk.
But what would the green wires be, and why is there only 1 pink wire, and 1 black??
hmmmm..........???

That looks like the entire bank 2 O2 sensor harness, pre and post for a 6.0L with isolated grounded O2 sensors. (Same harness I have for my swap)
The pre cat (bank 2 sensor 1) is would be:
light green/white and green for the sensor side and purple/white and tan for the heater
The post cat is the purple, pink, black and tan wires. Get a schematic so you can find the correct pinouts in the PCM.

its deffintly not the coil wires, i drive the car and the car runs.
Im really sure they are the o2 sensor wires but would the passengers side, and drivers side both be in that bundle? It kinda confused me cause i would have thought the drivers side would be of course of the drivers side like the LS1 harnesses, and vise versa.
I have a schematics, but i really dont want to start fishing wires, and pulling my PCM connectors back out. I custom statshed it in my glovebox...
Im almost 99.9% sure they are O2s. But i also pulled up my ALLDATA, and the wires for the sensors were the tan, pur/wht, pnk, blk
If i had a picture of the plugs it would be a whole lot more understanding for me...

ALLDATA is far from the gospel. They take the factory manuals and plaguris them and hope it never changes. With that being said, if you have a digital volt ohm meter it should be pretty easy. The sensor 1 O2's are powered from the PCM (the green wires) the rear O2's are powered from the same fuse as the MAF.
