Best Volvo V70 Trailer Wirings

Great build quality, but unfortunately it will not work to legally use a 4-pin trailer being towed by a 7-pin Euro/Land Rover plug. Its simply mapping 4 of the 7 pins to the following pins on the 4-pin side. Left running, Right running, Stop and negative, there is no provision for indicators or dual sided brake lights. It needs diodes (which it does not have) to do this. etrailer just needs to update the description as this is a good basis to make various adapters.

Received product in good order, well packaged, initial some delay, manufacturer was chased by etrailer, and earlier dispatched by manufacturer; delivery trail clear stated, very good. On receiving verified at UHAUL: connect with 1983 Land Rover (Defender) 110 Stationwagon (photo: rear, while on transport): all functioned ok. Apparently some diode(s) included, as the 7 pin has individual stop light which translates as left AND right indicator on flat pin. Emergency flashing (all indicators left and right) tested ok at UHAUL (connecting to trailer). LR has European homologated 3.5 metric Ton (7700 lbs) tow hook and has done some 60,000+ miles towing with current odometer reading 578,000+ km (on/about 360k miles)

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.

I received this product the other day and went to work installing it on my 1993 Jeep Grand Cherokee Laredo. This was done outdoors on a sunny 90 plus degree day on [the driveway]. Prior to buying I had read the online instructions and, more importantly, watched an installation video. The video was a huge help and the kit was very easy to install. The snap splice connectors work like a charm. I used extra zip ties I had to secure the power line in place as I routed it down the passenger side of the Jeep. Hook up to the battery terminal was easy. I did not have a circuit tester to check the individual wires to ID their function but since their colors exactly matched the video, I decided to take my chances. It worked out great. Installation of the power wire would be easier on a lift but I don’t have one installed in my driveway so it entailed crawling under the

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.

This is a great adapter to retro fit connections on my 2011 Expedition. Simple to instal and great support from etrailer.com.

I installed the pigtail on the fitfthwheel today along with the connector into the bed of the pick-up. I found the colors matched exactly on the fifthwheel and was fairly easy to install. I then installed the connector into the bed of the pick-up and found the assembly fit easily into the left rear quarter panel of the 2015 Chevrolet 3500. The wire colors were totally off from the truck wiring so a test light was needed to identify the location of each wire. Once this was completed the install was simply cutting and crimping wires. After the install of approx 2 hours ( I went slow to assure it was correct) I tested the circuits and found that all worked correctly. Looking forward to pulling and seeing how it functions.

Works great. My 2022 Escape TT has a pinbox so I removed the old 7 pin plug and cable and used it to cut each wire on the EZ Connector plug to the same length. Then I just matched the location for each wire with the assistance of a cell phone image. The two photos are before and after.

I really like the easy of use and security of how well it holds. A few small gripes though. One of the O-Rings tore very early on and I needed to order some replacements. Occasionally I don’t get a good connection and need to wiggle it.

I had to replace the old 7 wire cable because the male plug had been pulled off. I chose the WH54006-043 coiled cable. I used a 1/2 inch clamp to hold the cable up at the box and a Connect-to-Protect to hold up the male plug. The result Is clean and tidy. Thank you,

I just opened up my new Class 5 Curt XD hitch and have not yet installed it so my comments are based on first impressions only. It is very heavy duty - and heavy at 40 lbs. - made of extremely thick metal and outfitted with quality Grade 8 bolts with square necks so they won’t turn when torquing on the nuts to attach the main tube to the side mounting plates. My bolts are plated yellow (which I like) rather than silver as you may have seen in some online photographs. It is substantially beefier than my existing Grade 4 hitch and superior in every way. It’s an impressive piece of hardware. I cannot imagine anyone being disappointed with it on specifications, quality, strength, and general appearance. It’s a beast. What I AM disappointed in is Curt’s packaging and the condition in which the hitch arrived. (This is NOT a reflection on etrailer.com as the hitch arrived in Curt’s original packaging.) The unassembled main tube and the two side mounting plates come bundled together with nothing separating them but shrink wrap. No cardboard, plastic, even paper coming between the metal surfaces - just shrinkwrap probably not even a couple of mils thick. With basically metal-to-metal contact in an oversized-box with the bundle jostling around, it would be a miracle if there were no scratches, gouges, or some type of damage to at least one piece, which is exactly what happened to my hitch. The main hitch tube, on the exterior facing plane, on the driver side where I’ll see it every day, has some gouges on it that go through the powder-coating to bare metal. I can - and will - paint them to prevent rust (and, therefore, have to paint the whole hitch to match). But the gouges will still be noticeable as they go through the thicker, pebbly, powder-coat finish and will undoubtedly still appear as depressions in the surface even once painted. I fully realize this kind of surface damage will almost certainly happen with regular usage of the hitch anyway and that it’s certifiable to demand absolute perfection in anything. But if you are someone who cares about the aesthetics of your equipment and keeping it looking new for as long as possible, it is very disappointing to receive such an expensive and prominent piece of hardware damaged right out of the box and requiring immediate repainting. The plastic parts bag had also ripped open in transit, with nuts, bolts, shims, etc. rattling around in the box. I am dumbfounded that Curt packages such a high-quality piece of equipment so shoddily where such damage is virtually unavoidable. I bought from Curt solely due to their being an American manufacturer and to support American workers so this is doubly discouraging. It’s a trivial complaint in the big scheme of things and not worth demanding a replacement over. Just be aware that unless Curt changes their packaging practices it is very possible you will have the wind taken out of your towing project sails just as I have. Again, this in no way reflects on etrailer. My experience to date with etrailer (website, educational resources, staff reviews, ordering, tracking, email contact, etc.) has been beyond exemplary in every way. They rank as a Top Five online retailer in my opinion, maybe even the best.

I recently had a receiver hitch installed on my 89 Silverado and the wiring was merely zip tied to the safety chain connection. Well that didn't sit well with me. I wanted a more permanent wiring connection point. So I purchased your 4 flat to 4 flat and 7 way plug and installed it. So far so good. The installation turned out perfect and it looks good. The test lights are a great thing as well. I couldn't be happier.

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)

Product won't work correctly. I've tried it with 2 different trucks and 3 different trailers. Each Turn signal will active the hazard lights, and no tail lights. When pressing brake lights, all side marker lights will light up.

Well made is all I can say about this adapter only because I used it once it worked out great but have not had a need to use it again. I keep it with my other towing plug adapters as I'm sure I will need to use it again someday!

Not using on a trailer, but making disconnect harness for quick attach snowblower to loader arm. Connection cord is 7 pin tractor trailer tether, Worked well.

Product is high quality & works great! Can't beat etrailer

Items were simply “thrown in the box” WITH the hitch which was not secured properly. Heavy hitch then bounced around on electrical connectors, destroying them. Components should have been fastened to the hitch as the hardware kit was with strong tape instead of just thrown into the box by somebody! Refund issued.

Product arrived on time and as described. I used this for setting up our 2014 Wrangler Unlimited Sahara for a flat tow. Mounting hole spacing @ 2" o/c didn't match our Blue Ox 1126 draw bar so I fabricated my own intermediate bracket, polished it to aircraft tooling standards, then lacquered it before final assembly. I think the finished product came out nice.

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 installed this connector on my travel trailer. The original connector had become loose and would fall out if not retained by the tab on the bottom of the connector. After a year of usage The Pollack connector still snaps into place and fits tight. Good product.

Routine trailer maintenance. Absolutely nothing worse than fighting trailer lighting or electric brake issues when traveling.

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.

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.

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.

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

Great product. Works well when I had a broken connection on my 4 way plug end on my light-up hitch cover I bought from y'all a while back. Always a happy customer. Thanks, George.
