Upgrading 4-Way to 7-Way Trailer Connector on 2019 Nissan Frontier
Question:
I purchased the T one wire harness for a flat 4 plug from you all for my 19 nissan frontier. It works great! Id like to upgrade that to having a 7 pin as well. Im ok with just replacing the 4 pin outright but if I could have both the 4 and 7 Id like to go that route. Any advice would be appreciated on what I should get to achieve this. My vehicle did not come with a factory wire harness so I purchased your all in one kit. Thank you and I look forward to hearing from someone.

Since you already have a 4-way on your 2019 Nissan Frontier adding a 7-way is pretty simple. Using part # 118267 gives you a 7-way but doesn't keep your 4-way.
To keep the 4-way with the new 7-way you can use part # HM40975 instead of the connector included with # 118267.
If you also need a brake controller I recommend the Tekonsha BRAKE-EVN, part # 5535, with the adapter harness # 3050-P.
