Does Tekonsha 7-Way 118273 For 2018 Nissan Pathfinder Provide Charge to Trailer Battery


For my 2018 pathfinder using the 118273 wiring harness-will the 7 blade provide a charge for the trailer battery while driving?


Expert Reply:

A 7-way such as the T-One Vehicle Wiring Harness - 7-Way Trailer Connector # 118273 that fits your 2018 Nissan Pathfinder will provide a maintenance charge to your trailer battery while you are driving, though it won't charge the battery from a depleted state.

To charge your trailer's battery while you were driving, what you would need depends on the amount of amp hours your battery is rated for, either Redarc In-Vehicle BCDC Battery Charger # RED96FR if your battery is rated for less than 75 amp hours or # 331-BCDC1225D if it is rated from 75 to 200 amp hours.

In regards to mounting the # 118273 7-way to a trailer hitch on your '18 Pathfinder such as the Draw-Tite # 76031 you will need the Mounting Bracket # PK12711U.

The Draw-Tite hitch I mentioned has a welded-on bracket which you can attach the Mounting Bracket # PK12711U to; if you have a different hitch without a bracket you would also need the No-Drill Mount # 18140.

I also highly recommend using Dielectric Grease # 11755 in order keep your 7-way as safe as possible from corrosion. I have added a link below to a video install on a 2018 Nissan Pathfinder for you to check out as well of the T-One Vehicle Wiring Harness - 7-Way Trailer Connector # 118273.
