Most Popular Trailer Connectors for 2005 Mini Cooper

Sooo, bought another one to match my truck side connection as GM uses Pollak, which are known to not play well with other brands. The design is just a wire clamp to wire it, which I did with the first one, but trying to get it secured I stripped out the screw. There are no torque specs provided. I’ll move to crimped ring terminals on this one and dial back the torque a bit.

Used as a replacement for original connector that didn't have a positive fit. This one clicks in and provides confidence of a snug fit.

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,

This should work great, installation is still on my to do list.

good quality connector just what i was looking for

I periodically pull a 12v pressure sprayer behind my lawn tractor. The 12v harness I originally made that clipped to the tractor battery was always cumbersome and became hazardous when it recently shorted out due to rubbing (and no fuse in line). So I finally took the time to do it right, mounted this connector to the rear next to the taillight, and created a hidden fused permanent harness to the battery, and of course utilized the mating connector for the sprayer harness side. This little connector was perfect, high quality materials (connector body and electrical terminals), high spring force on the cover when not in use, nice sealed design yet easy to plug/unplug. Very happy with this purchase and will likely buy it again.

A great little heavy duty plug that I use to connect my car to the rv when towing 4 down.

Great products, very good quality, completely satisfied

Worked excellent for wiring my cab over camper to in bed trailer plug-in.

Quick shipping, will order from them again!

Exactly what I needed and It's a great fit

Hot garbage. Terrible design that I'm stuck with because my trailer tongue is drilled for this plug shape and dimensions. If you look at the pics, the screws are at the back of the wire connector so the wires must be inserted at a 90° angle to the plug. If you tighten too much, you'll start shearing off strands of your wire. I ended up spending a couple of hours soldering in my wires through the screw threads and it's still a shakey looking affair. If you're options allow for literally any other design, don't buy this thing.

The pins were too big by a little bit. Had to force the female plug into the socket

Used on a pull behind motorcycle trailer so could go from receiving a 6 pin to a 5 pin. Wired it into loom so can use on more than one motorcycle. Works great. Glad to have found a place that even sold this product.

A similar trailer light connector was installed on my motorcycle cargo trailer when I purchased it way back in 2003. When I purchased my new Gold Wing in 2019, I wanted to use the same type of connector. Since I had to add a new female connector to the bike, I decided to renew the male connector on the trailer. I especially like this connector because it always stays secure when connected. I also wanted the connections to be out of sight when not in use. I have pulled my trailer with this new connection for over 2,500 miles and it has performed great.

it is not the larger size plug that was originally on the trailer and i discussed with the service advisor when i called, which means i have to buy a transition plug.

I used this molded connector/cable to make the electrical connection between my truck wiring and my slide-in truck camper. It was easy to install and has worked flawlessly since.

product from Pollak is always great but they packed it with steel couplers and destroyed it

It is a direct OEM replacement, easy installation. What I liked most was a real person answered my call and took my order, Katherine was very polite and knowledgeable. Thanks again. CJ

Installed the Hopkins muti-tow 7, 5, and 4 way flat connector this morning. I ripped the original connector that was attached to the bottom of the hitch receiver off when I was 4-wheeling into the Doll House campgrounds in the Maze District of Canyonlands a month ago. So, I cut a hole in the bumper and mounted the new Hopkins connector, cut off the old broken connector mounting bracket, and connected the factory wiring to the new Hopkins device. Hopkins product installed easily, looks great, is now out of the way, and has the flexibility of multiple trailer connectors when required. I am pleased with the product. Attached is a photo.

Exactly what we had been looking for. Now I can hook up multiple trailers with different connectors and all the electrics on each trailer works. I mounted mine directly to the receiver hitch frame. The biggest challenge for us was routing the backup wire from the taillight housing, through the body of the truck to the connector. the rest went together fairly easily. Seems to be pretty solid and looks much better than the loose pigtail connector it replaced.

I used this harness to rewire a 10ft vintage RV. There was plenty of length to reach the rear lights. I used Scotch Locks to tap into the wiring for the side running lights. Very good product.

Very happy with every aspect of my order. Received product and quality appears to be outstanding. I’m especially impressed at the instructions made available to install the wiring harness, written with the product and link for video. All bases covered and follow up to make sure all goes well. Am confident of their assistance should I need it.

Used on tow vehicle for hooking up wiring harness to motorhome

This part is an exact replacement to the part that failed. The failure was caused by a poor installation which allowed the rubber boot to chaff on the truck frame. As it was an exact replacement installation was straight forward although I modified the mounting bracket to prevent a reoccurrence of the problem.

I've had this in use for over a year and they don't build them like they use to. I use this on a gooseneck trailer and the piece of plastic behind the spade connector for the clearance lights and brakes has melted, allowing the spade connector to lose contact with the plug on the pickup. So the lights would cut off in the middle of the night and would have to wiggle the connection till I could fix it. I have an older Hopkins plug and never had this problem. To fix the problem I ended up putting pieces of thin copper wire behind the spade and have done it twice since the plastic melted a 2nd time and once again the trailer clearance lights would quit working. Attached are before and after pictures.

These connectors are of very high quality and make for a professional installation and appearance when used with LE$D lights and Dexter brakes. The different color of the wiring is a very minor obstacle. Using the wiring junction box really enhances the installation of the connector.

I've got that trailer that has had one tough life. Yep, hundreds of gigs, PA and sound equipment rolling in and out, the heat, the cold, the sun, rain, and snow. Chicks, guitar players and drummers, you know, all the things that beat the hell out of a drum! Thank the music Gods for etrailer.com!

I've never really liked Flat-4 type connectors. Unless you leave them dangling, they usually require that you crawl under the vehicle to connect them. (...Murphy's Law dictates that this will always be when it's raining or snowing). This Pollak 4-pole round socket, along with a Tow-Ready harness, and matching trailer connector, provides a neat, factory installed look, that's more convenient, and durable. My orders from etrailer arrived quickly, and with great seller communication. A+

This is a piece of junk….one of the male plugs was broken and I checked the current on the others and no current passed through from one side of the plug to the other. Complete Junk….do not buy this product. I ended up going to [store] and getting a curt plug that worked just fine.

I explained to Roger (I believe was his name) that I have a Blue Ox tow bar and base plate, The base plate was installed along with the wiring kit, but did not include the wire to go from the front of the grill to the interior of my Jeep to plug in my RVi brake, and this is what he sent me. I'm attaching a picture of what I have on my vehicle. Not only was it the completely wrong part, but it arrived in damaged packaging which I did not open. Please send return instructions.

Just what I needed for my home-built bike carrier. My wife rides an e-tricycle and by the time I loaded the trike and a couple of bikes on this platform, you could not see the car's taillights or blinkers. This harness worked perfectly!

Wiring worked perfect for my project. I replaced the wiring on my 14 foot utility trailer. If I was to do it again I would buy the next length up. I would have liked to have a little extra wiring if I was to ever need it.

Great quality exactly what I was expecting

I was expecting blade connectors as shown in the pictures and video and that is the main reason I purchased this item. Instead it had screw connectors.

Wiring and new self adjusting electric brakes were a simple install and work perfectly. The etrailer online video and written instructions made the job easy.

I needed a plug so I could pull my boat behind my camper. It was just the right length.

I decided this would be cheaper than any extension I could find, plus I'm going to shorten the wires anyways, so it's no big deal if it's in two parts already. I have a powered light adapter that's intended to be located outside, but I don't care for the idea of having that power wire running out to the hitch, so I'm going to use this kit as an extension so I can keep the adapter inside the car. My car has auxiliary wiring sockets to plug a trailer harness into, so I wont be using the included splices, but those look fairly decent. I would recommend packing those splice taps with grease, to keep water out if you use those sort of things. I usually don't

My 12 ft utility trailer needed a makeover, I stripped it down, installed new boards, repainted I and installed new wiring and lights. I ordered the wiring and lights from etrailer and they arrived in about a week and everything I ordered arrived in perfect shape. It installed very easily and worked perfectly when connected to my vehicle. Thanks etrailer for delivering on quality products and great service. Marty, Peoria AZ
