Parts Needed to Install Trailer Wiring Harness on 2017 Nissan Titan
Question:
Hello, I have a 2017 Nissan titan with gas engine. What wiring harness would I need for at least a 4pin? I have no wiring from the factory. Thanks!

I recommend using the Factory Style 7-Way and 4-Way Flat Vehicle End Trailer Connector # N40975, which would give you both a 4 way and 7 way trailer connector and uses the US car connector wiring that is present on all 2017 Nissan Titans. This kit comes with the relays included needed to activate the factory tow package wiring and is a great solution that gives you everything you'd need to tow trailers with either connector.
There is not a harness available for only a 4 way, so this would be the best solution available. I've linked a review and installation video of this part for you to check out.
