shouldn't have to do all that, the tow button is integrated into the shifter arm and just snakes down under the column and then down to the bcm. if the wire is broke right at the shifter arm too short to repair then just get a new shifter arm. typically the wire breaks right wear it pivots from the shifter being moved up/down
just remove the plastic cover around the steering column and you have access to it right there.

Added a factory tow hitch on my recently acquired low mileage 2002 Yukon. It had the harness tucked underneath with a factory installed plug.

The tow / haul button on the column shifter didn’t do anything when I checked it a couple days ago but hopefully it does now… (if it doesn’t I saw somewhere here it was a common problem from a wire getting chewed up in the column)

What is the factory manual torque spec for the 6 grade 10 metric bolts for the tow hitch ?

PS: I picked up 2 tow hitch receivers on marketplace last evening, thankfully one of them (off another Yukon) bolted up. The one off the Yukon XL didn’t and it required one of the bolt locations to be modified slightly so I’m glad I picked up 2 of them.

Tighten the bolts to 125 NM- (92 lb ft)

I got in there and saw that everything looked too clean to not work. So I pressed the tow haul button a bunch of times and now it works. I’m gonna guess the button/switch itself developed some kind of contact resistance since it has never been used in the 22 years and 89k miles ? :hmm:

Update later in the day: Not so fast. I went back there this afternoon. The button didn't work again but I yanked at the orange wire through the shift lever boot and it worked.... so I'll need to investigate that further, apply one the known solutions...

In the off chance this thing isn't working while I'm towing something, can I just be in 3rd gear manually and that should prevent the torque converter lock-up correct ? If so, I am not going to bother with it at this point........ I have 2 other towing rigs so honestly I am not even sure when I'd be required to tow with this...
