Once installation is complete, the connectors will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket is included to keep the connectors secure.


It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 7-pole and 4-pole connectors - to help prevent corrosion.

2014 Nissan Frontier

Recently went into business for myself. My old plug on my 2014 Nissan Frontier was not holding up. I messed it up during the install. Needing to pull a trailer I began searching for a plug that would work. I wanted something that was plug and play and allowed either a 7 way or 4 flat connector. During my search i came across the Hopkins Plug-in. It is designed to be mounted underneath the truck with the provided bracket. I emailed etrailer.com. I got a response back almost immediately from George. I told him what my plans were for the connector. He said that it should work as the connector didn’t need the bracket to be mounted. Since I already had a hole drilled to 2 1/4”, I prepared myself to notch my bumper a little in order for it to fit. What a pleasant surprise, this connector fit right through my previous hole. I did have to drill 4 additional holes 11/32” to mount it. I used paint primer to cover those holes up before permanently installing the connector. It truthfully is plug and play. I have attached pictures of what it n ow looks like. I highly recommend this product and company.

Everything came packaged just as described. I bit funky to install the nuts and washers due to a lack of access in the factory bumper, but all in all it got mounted and works perfectly.

Good concept but not the best product. After spending the time on install, I connected the trailer only to find that the seven pin harness does not stay in the Hopkins unit very well. I am hoping that it doesn’t come off during towing. Hopkins customer service is worthless as I got no response back from them.


Comments
How old is your trailer plug? You may need to replace it if it is not staying in properly. I would replace it with something like item # H20046
Hopkins 7-Way RV Style Connector with Molded Cable - Trailer End - 8' Long - RV Standard
$46.90
but if you do not want to replace your whole cable, then this item # PK12706
Pollak Black Plastic, 7-Pole, RV-Style Trailer Connector - Trailer End
$5.04
is fine too.

Since hitch did not come with plate to install this piece on the truck, I am having to make an appointment with a shop to assist me with installing this product to my truck. Looks like a good product and does work when installed, but until I get the mount to install I will not recommend this seller.


Comments
You can add a plate to the hitch with long bracket part # 18136
No-Drill Mount Bracket, Long
$16.46
. This is a no drill bracket so you can attach the wiring to the hitch. Otherwise you would need to drill into the vehicle.

installation was slower than I expected (Not a product related issue) but was due to the bumper on my truck has a tubular design, so access to the back side made it hard to get the screws in place for the bracket. However the connectors fit and all is good.

This worked great on my 2016 nissan frontier. It has A factory tow package and the dust cover for my 7 pin had broken off, I purchased this and gained the 4 pin as well so i dont have to carry an adapter plug around with me anymore. Instillation was simple only taking a couple minutes tops ( the holes dont line up to the factory plate so had to drill them for mounting hardware) great product just took a while to recieve it

I recently purchased this with a Curt hitch for my 2020 Nissan Frontier, and while installing the wiring harness I couldn't figure out how to plug the connection into the truck. I called etrailer and Melissa T answered my call, I explained my dilemma and emailed her a picture of the under side of the truck. She went above and beyond the call of duty and emailed a video to me that explained how to connect to the factory installed plugs for the light kit. Melissa T is a valuable asset to etrailer, without her I'd probably still be lost. Thank you for having caring, understanding, knowledgeable staff, just a phone call away. etrailer rocks!!!

Good quality product that installed fairly easily onto my Nissan Frontier. The trick I used to get the nuts and washer in the frame was to first super glue them together, then slip it up into the frame, and finally install the bolt.

  • How to Install the Hopkins HM43534 7 Way Adapter On a 2014 Nissan Frontier
    The Hopkins Plug-In Simple Vehicle Wiring Harness for Factory Tow Package - 7-Way and 4-Flat Connectors # HM43534 is actually a plug and play option for your 2014 Nissan Frontier. Though this will come with a bracket to attach it to the bottom of the bumper or in some other way, you may be able to mount it in the hole you already have in said bumper. The holes will measure 2-1/2 inches from center to center when going across horizontally, so if this matches the mounting holes you already...

    The Hopkins Plug-In Simple Vehicle Wiring Harness for Factory Tow Package - 7-Way and 4-Flat Connectors # HM43534 you were looking at for your 2019 Nissan Frontier SV is an exact replacement for the factory 7-way you have installed, and will give you both a 7-way and 4-way connector.

    On your 2019 Nissan Frontier that came with the factory harness, you will only need to plug in the Hopkins Plug-In Simple Vehicle Wiring Harness # HM43534 once. Then when you need to use the towing connections you will just plug into either the 4-way flat or 7-way blade connectors. Some Dielectric Grease # 11755 is recommend on the connectors to protect against corrosion and other wiring issues.

The Hopkins also has a 4-way on the side of the 7-way so it covers both standard wiring configurations. Basically the tow package means the vehicle already has the relays and harness.
