I had to do a little figuring of where I wanted to put it and how to install it on the car, but ultimately it is working fine. The bracket is a little flimsy but if you push it forward with your other hand when putting in the connector it works fine. 846001

by:

I just got it a few days ago and it is not installed. But, it came with mounting hardware and bracket, so that is nice. The wire harness also plugs into the main body which is also a nice feature. I also like that it has a secondary 4 pole socket directly below the 7 pole in case you are pulling a utility trailer without brakes. Build quality seems good. It is all plastic, but doesn't seem flimsy at all. I would recommend this product. Note that a 7 pole has extra circuits for: 1. charging rv or trailer brake battery 2. rv or trailer brakes 3. backup lights (center pole and purple wire) 844984

Really easy to install. Plugs right in to the flat four wiring. I found a decent spot to mount the bracket and finished the installation. 5 minutes max.

  • 7-Way Adapter Recommendation for 2016 Honda Odyssey EXL with Aftermarket 4-Way
    For your 2016 Honda Odyssey that has an aftermarket 4-way you'll need to use a 7-way adapter like the # 37185 to convert to a 7-way since your vehicle does not have 7-way or brake controller factory wiring. That said, I would recommend the part # ETBC7L for the 7-way adapter and then for a brake controller the Curt Echo Mobile # C51180 as this is the easiest to install and best option. Once you plug it into your 7-way and it's synced to your smart phone it's totally ready to tow without...

  • Difference Between 4-Pole to 7-way Wiring Adapters 47180 and 37185
    Hopkins part # HM47180 is a 4-pole-to-7-way wiring adapter that is equivalent to the similar # 37185. The only real functional difference between them is that on part # 37185 the 4-pole trailer connector is located to the side of the 7-way, rather than under it as with # HM47180. Both adapters plug in at an existing 4-pole vehicle connector and re-format those lighting signals to the 7-way configuration. The 7-way can be wired, if desired, to add new functions by using the included pigtail...

  • Installation Video of Brake Controller and 7-Way Trailer Wiring on 2016 Chrysler Town and Country
    I attached a video from when we installed a Prodigy P3, part # 90195, in a 2015 Chrysler Town and County. Your P2, part # 90885, is the same process and it'll be the same on your 2016 as well. In the video we also use the # ETBC7 kit for the wiring. You could have gotten our # ETBC7 kit which includes the 7-way adapter and all the wiring, connectors, and breakers you need but since you already have the Hopkins # HM47180 you can add our # 5506 kit for the rest of the parts.

  • Where Do Vehicle and Trailer Wiring Harness Ground Wires Connect
    The ground wire on a trailer's wiring harness (usually a white wire) should be firmly attached to clean bare metal on the trailer frame. The white ground wire on the vehicle's wiring harness should similarly be attached to clean bare metal on the vehicle, or to an existing factory grounding point, or even directly to the battery negative terminal. When the trailer and vehicle are connected together through their 4-pole wiring the trailer will ultimately be grounded to the vehicle battery. Bad...
