Most Popular 4 Flat for 2018 Volvo V70

Used this with a 2004 Volvo that has european wiring harness. Plugged right in and the lights, brakes, and turn signal all worked as needed. Plugged right in without any hassle, and half the price of a similar adapter found on eBay. Only concern is the all plastic material makes it easier to damage.

It worked on my Volvo v70 Oem harness. I was able to use this and the indicator lights for a trailer even worked on the instrument cluster for when a trailer was connected.

Excellent. The only down side for my Lexus RX300 was not having an “easy” way to mount male 4-way next to hitch rather than stowing it beside tire bay. No big deal just a plus.

Really nice trailer wiring adapter. Very easy install. Takes about 30 minutes with all the tools needed. Drill, 7/64 bit for pilot holes to mount the bracket, flat blade screwdriver and 11/32 nut driver and two #10 self tapping metal screws with locking split washers and a couple zip ties to tidy up the wiring harness.

I looked at so many options before deciding on the B&W hitch, but I have no regrets buying it. There is nothing that my car is suitable for towing that this thing can’t accommodate. I even use it on the front hitch of my mower to move trailers around the yard! Adjusts very easily and stows nicely (though on my Ford Edge it rides lower than I like when stowed).

Not too difficult to install, but I would recommend using a car lift so you don't have to work from your back (review includes wiring harness and Brake Controller)

Perfect . My new Subaru hitch has a flat plate to which the dealership attaché the 4-flat. I used “2 L-brackets” to accommodate the 90 degree bend of the adapter bracket.

Arrived quickly. I didn’t need to wire the extra lead to my reverse lights because my trailer doesn’t have surge brakes or backup lights. Simply plug and play.

Perfect for converting 4 wire Ford Expedition trailer harness and boat trailer to 5 wire. The Expedition had a backup wire run to the area of the 4 wire plug so made the conversion easy.

I have now installed the following on my 2017 Wrangler: Brake light relay kit . Hopkins Towed vehicle Tail Light wiring kit. Blue Ox base plate. Blue Ox Patriot Portable RF Braking System. All of this has taken about 3 days of work spread out over a week or so. Overall it went well. Not too many surprises. Crawling around under a car at 71 is a bit of a strain but I'll get over it. I must say that Donna P. has been a wonderful source of great information and has stayed right on top of the process. eTrailer has been a great source for this project. I would recommend you all with no hesitation.

The items I ordered will allow me to adapt my utility trailer for transporting my sea kayaks. Curt and Hopkins are both quality manufacturers. On a shipping note, the box arrived at the Post Office broken wide open. Your shipping folks need to wrap small, heavy, items in bubble wrap. Then stabilize it with foam peanuts. Just putting it in a box then stuffing the box with craft paper does not cut it. Items were not damaged so I am good to go.

Great product no issues at all. Product as described & fit properly.

Pretty straight forward. I used it to switch my European trailer's connection to be able to connect to my Wrangler's 4-pin trailer hookup. No issues. works great.

Nice product. Appears Heavy Duty. Doesn't seem cheap. Would recommend this product.

I rewired my light bar for my boat trailer with the items I purchased. Before I built the the light bar, every time I used my boat trailer I would waste valuable sailing or fishing time repairing faulty lights. The do not last long when you submerge them in salt water. This light bar now version 3.0 have given little trouble over the years
