Rear Wire Harness Underside

[42ezra]

I just noticed a healthy wire harness and connector hanging near the exhaust tip. Why I haven't burned that up I don't know but what should I do about it? Probably runs everything in the back?

Send a picture. And, by the time the exhaust gets to that point with the airflow if probably has little effect on anything near it.

most likely it is for the backup sensors and maybe part of the tow package, I would just zip tie it up securely up as high as you can get it

Also, please provide your make/year/model/trim information for your truck.

That is probably for the blind zone sensors and needs to be put back up in its mount.

I have the same problem on my 2019 Tahoe LT. I was on a long highway trip and the connector was hanging about an inch from the output of exhaust pipe. The heat melted the connector pretty bad. So much so the plastic connector release is fused to the connector. No errors and everything still works. Part is a Rear Harness Junction Connector parts D33C40 and D33D40 for the male and female sides of the connector.
Dealer wants a fortune to fix it. My plan is to purchase the connector without wires and transfer the wires to the new connectors. The pin areas look like they are all okay still.
I need a little help figuring out the pin sizes or tool sizes I need to de-pin the connector wires if anyone has any insight to that.
Thanks!

Just an update to my post. Purchased the D33C40 and D33D40 connectors from Connector Experts dot com. They said they get a lot of orders for these for the same reasons I had. My suggestion for anyone that has this connector in the bumper is to zip tie it in place.
The tool needed de-pin the harness was found in a tool kit on Amazon:

23-Piece Universal Terminal Release Kit-Universal Electrical Terminal Removal for American Domestic and Imported Vehicles​

Tool needed was Tool #21
Since my connector was pretty badly melted from the exhaust, it took some time and effort to "de-couple" the melted parts. I ended up having to use a heat gun to soften the plastic and screwdrivers to wedge a gap from the male and female parts to get the connector apart. Once apart, the process was easy.
