The difference between the Class II and Class III hitches has to do with their Gross Trailer Weight (GTW), their Tongue Weight (TW), and their Hitch Receiver Size. Class II trailer hitch receivers have a 1-1/4 inch receiver and can be rated up to…

Your vehicle requires a converter to convert the trucks 5-Wire system down to the 4-Wire system used on trailers. You will find a connection point behind the rear bumper on the passenger side frame rail, that you will use to plug in the Plug-N-Tow…

So you will need to access the 12 pin jumper plug in your Frontier's cab, which as you said is on the passenger’s side behind the kick panel. This is where you will install the harness and relays that activate the trailer tow package, and the…

Most often the root cause for issues with trailer lighting is a weak ground. Strange as it may sound, a loose or rusty/corroded ground can cause a vehicle's trailer wiring harness to badly misbehave and shut down some functions. It may also just…

Sounds like you have a ground issue on your trailer. Ground problems normally show up when there is more draw on a system such as when you have the running lights on and then use another function like a turn signal or brake light but can show up any…

A standard 7-way is going to work just fine on your trailer. That converter circuit will be for a 12 volt power source which a 7-way is going to have on the 1:00 pin. For the trailer side you would want the part #H20043 and you would be good to go.

The Kenda Trailer Tire with Galvanized Wheel #AM30630 is a bias tire which has cords inside which run at a 32 degree angle to the direction of travel for a stiffer sidewall than a radial tire. This tire has the standard speed rating of 65 mph.…

I've linked you to the available hitch part numbers for your 2012 Sienna. May I make a Recommendation? I'd personally choose a Class III hitch like the Curt part #C13343. 2 Inch Class III hitches have a much better selection of hitch mounted…

Brophy mounting bracket #BK4F is designed to fit a standard 4-Way flat trailer connector so I don't see any reason why it wouldn't work with Hopkins wiring harness #HM43575.
