New Engine/Transmission wiring Harness

[Capeasy]

Are these wire Harness's still available for a 13 ? I already looked on the GM parts links and it seems they only have the V6 wiring.
I'm not sure if anyone else has experienced the wires that are exposed where they go into the sensor connection getting hot from the exhaust causing the insulation to either burn or deteriorate and crumble off which then could short out?
I was just going to replace the O2 pigtail but after pulling out the Harness all the other sensor connections ,Knock, crank position, and of course the O2 are bad.
I think a new harness for the R/H pass side would be the best fix if it's still available somewhere.

If it was me I would just buy the new connectors and splice in some new wiring and connectors. Solder and heat shrink all splices. I have replaced my knock sensor, O2 sensor, and rear head ground on mine.
