Default Installation instructions for a 478A0EZ40B brake controller.

I have a 2017 Nissan Titan SV that was not equipped with the factory trailer brake controller. I have purchased a new factory controller. I am wondering if there is an installation guide available for this controller?

From what I understand, you cannot add the factory trailer brake controller to a vehicle that did not come equipped with it from the factory, as the main harnesses are different and there is no connector for the controller to be plugged into. If not equipped from the factory, you would need to add an aftermarket trailer controller. I also did a quick web search and found this thread on a Titan forum:

I went back and fixed my link, which might help. I don't know if they changed it with the 2019 models, but it looks like you unless you had it from the factory, which would come equipped with the harness connector for that module, you would have to go with an aftermarket controller. There are a number of decent controllers on the aftermarket; my preference for brand is Tekonsha and the Prodigy 3 is a really good controller. Etrailer.com carries that and others and has plug'n'play harnesses. If you find out anything different, please update the thread!
