Towing with ACC and an after market TBC?

[CityHicks]

Hi,

After looking at the manual it states:

Page 358:
Towing A Trailer
ACC while towing a trailer is recommended only with an Integrated Trailer Brake Controller. Aftermarket trailer brake controllers will not activate the trailer brakes when ACC is braking.

Has anyone verified this? I ended up installing my old Tekonsha P3 brake controller because I know how it works and I already had it instead of waiting for the Mopar integrated TBC that's on indefinite backorder. Has anyone had any issues with ACC while towing either with the integrated TBC or aftermarket?

I answered my own question while towing this weekend: It DOES in-fact turn on the trailer brake controller when in ACC mode, but I am using a Tekonsha P3 not the factory controller though I am using the factory plug that was located behind the dash. It applied braking voltage in normal driving and in TOW/HAUL mode.

Where is it behind the dash?

Where is it behind the dash?

The connector? It's to the right of the steering wheel, and directly up. I think it was taped or zip-tied to a cluster of wires. I had to buy a DODGE/RAM adapter for the Tekonsha to plug into it.
