Has anyone added a towing hitch after?

I don’t have trailer stability control or any of that, but I was able to wire up all the lights to work correctly and I don’t get error codes. I used a Bronco trailer wiring harness. My point is, it can be done without running it through the Grenadier system.

Nobody is saying you can't do that or that it would cause issues.

I'd love more details. When I asked the dealer about adding the ability to tow to mine they said sure no problem, I just noticed this morning (picked up last Friday) that they added the hitch but not the wiring. I'm not afraid of digging in but also no sense in re-inventing the wheel if you've already done it.

I'm bit unsure why but my order doesn't have the towing hitch. I'm pretty shocked by that I must have accidentally not selected it when running other options. Anyone do the same and add one after the fact? I guess so long as the framing is there it's not that hard. Just wire a harness into the rear tail lights.
So my understanding is you can slap the hitch right on, its the 7 pins plug and how it communicates with the ABS and sway mitigation in the vehicle software and that is the rub. I am digging in to see if i can wire a 4 pin so i can at a minimum do dump runs and maybe a small boat with a trailer not needing its owns breaks…TBD…. Would love to hear if anyone has has success. Talked to two dealers both said it has to be done at time of order which seems wild….

Their view on this is for factory/OEM integration.

You can absolutely wire a 4 pin (or even a 7 pin) with a universal wiring kit and tap off the taillights for the required signals

Anyone have any pictures of where theyve tapped in to the tail lights youve come across? Ive been digging and havent had luck finding any but would prefer to copy a successful process than just wing it on my own….

I think this one will go down on the list of "WTF were we thinking" for Ineos engineers. They should all just simply come with the hitch and wiring from the factory like ALL other trucks on the road. The costs of adding the stupid warning, fielding endless questions on how to add one, dealers butchering later installs, wiring vehicles 2 different ways on the assembly line....pretty dumb if you ask me.

Globally, towing is not a huge expectation of a vehicle, the RoW cares more about payload (one of the key reasons why the RoW gets the payload-focused Hilux and we get the towing-focused Tacoma). Was this an oversight? Possibly. But in the grand scheme of sales, a fairly small number of people have an "issue" of not having the hitch when they wanted one, and a good chunk of those people have no interest in the hitch for towing, but instead for accessories, which simply requires purchasing the hitch and bolting it on.

There's nothing for a dealer to butcher, as there is no factory approved way of adding everything else required. The wiring differences on the assembly line are only from the towing control module to the rear bumper; less invasive of an assembly line alteration than adding the NATO plug that comes with the high amperage switch panel
