Today we'll be reviewing part number HM47605. This is the Hopkins Knockout Adapter for a four-way flat trailer connection. This adapter is going to plug in to your vehicle's four flat trailer connector so that you can mount the connector in an inch and a quarter diameter hole. It's a very versatile installation. This will mount in a six-way round bracket, which is going to be sold separately, part number HM48605. It can also replace one of the vehicle's license plate lights. On this side here we have the dust cover that's going to help keep out dirt and moisture. It simply just fits over the four flat connection, providing a nice tight, secure fit. This is made from a durable PVC construction so it's going to be very strong, very durable and again, that dust catcher's really going to come into play when it comes to keeping out dirt and moisture. That's going to do it for today's review of part number HM47605.

Keep your 4-pole flat trailer connector accessible with this adapter that lets you mount the connector in a 6-way round bracket (sold separately) or in a 1-1/4" diameter hole.I am very pleased with the products and service provided by etrailer.com.
The 4-way Curt trailer hitch wiring connector and Hopkins Adapter for my 2015 Honda Pilot were easy to install with the clear and well illustrated directions. They are performing as advertised with no additional troubleshooting required. The quality suggests that they are durable and will last for at least as long as I own the vehicle. I currently tow boat trailers. The car came with the OEM trailer tow bar (hitch) and basic internal trailer wiring. The etrailer.com parts were just what I needed to complete the package.
[I suggest you include a note to install the provided 10A blade fuse in the holder on the S3 harness in the installation instructions]
Worked perfectly. Unfortunately ran into a deer two months ago and.dont have the vehicle now

Put on new vehicle. Works perfectly. Looks like factory.
I used this device to tidy up a recent hitch and wiring install on my Volvo wagon. I ran the receptacle out the bottom of the car and just zip tied it to the hitch. It looked OK, but I wanted something cleaner that didn’t involve attaching a bracket to hold the 4-pole connector. After a few minutes of searching I found this device. All I had to do was buy a 1.25” hole saw for my drill and the rest was easy. Drilled through the plastic fascia on the underside of my bumper. I think it looks great! Attached are before/after pics. Another great experience with eTrailer.com!!!
A great adapter for a clean practical look on plastic bumper moulding.
Quick and easy online ordering.
I used this to make an easy trailer connection for my wife's CanAm Spyder. It works perfectly! It was easy to install and it was "Plug and Play". Thank you for providing this product.
Quick install, just drill a hole and pop it in. 4 stars because I don’t like how it sticks out so far and is noticeable. The manufacturer may consider designing one that is recessed in farther even if you need to drill a bigger hole. Love etrailer !
Great quality, will work for my application. I was worried I would have to make an odd hole, but cutting a circle with a hole saw will work perfect.
Worried as first because the picture with instruction showed an adapter and I had a curved surface on my GMC Terrain at the mounting point. Worked great and did not een have to take the ld pigtail off.

Perfect! I did sell the Terrain and the new owner thought the trailer wiring looked like it was from the factory. Kudos, Etrailer...
I'm writing from Canada. I ordered the Curt receiver trailer hitch, and customized wiring harness. Although it took a while to get here, the product was exactly as specified, installed quickly with good instructions. One word of advice, use at hoist to install the hitch, laying on the garage floor and tightening the bolts to specs. just about did me in, maybe I'm getting to old. The wiring harness was a breeze to put in with excellent instructions. Good product and service.
Worked great. Needed to locate flat 4 through to my hitch electrical mounting plate, fit perfect and great prive

Exactly what I needed to clean up the installation of my trailer wires on my 1995 Ford F150.

Excellent! It is still perfect.
Great service. On time and accurate!
Just installed it today 8/21/21 on bumper sure makes it easier to get to I don't have to reach under bumper to hook up
great product. just what I needed to get the wires neat and out of the way.
I ordered the wrong part. What I need is a dust cover for a 5 wire flat trailer plug.

I will have our customer service team reach out to you.
I am always pleased with how etrailer treats my orders. I am angry with myself for ordering the bracket for the socket attachment ( realized that I already had one), but the order was filled the day I would have canceled--so I just let it go.
I added this to my 2002 Ram 1500. I drilled a 1.25" hole in the plastic plate next to the license plate and mounted it there. It was easy to install and makes my wiring harness easy to access. Good quality.
Nice solid chunk of plastic. Didn't come with any grease, but that's ok. I'm using a small amount of a very thick silicone plumbers grease to keep the connections from corroding & adhesive lined shrink tubing on the inner connection, because that's going to be out of reach inside a plastic bumper cover
Decided for now not to install product I changed my mind and wanted to stay with the clean rear bumper cover with the Ecco hitch hidden trailer hitch.
It might have fit something, but not my truck bumper. The hole for the license plate light was way bigger than the adapter.
I have purchased several items from the etrailer.com folks as always a smooth transaction with no problems. That's why they've become my "go to" vendor for trailer related products. Good product,fair price, great service before and after the sell, what more can you ask!! Good folks!
Quick delivery and works as expected.
