35 Ft 4-Way Trailer Wiring Harness - Wishbone Style - 42" Ground
Replaced the wiring and lights on my 1992 boat trailer. I was able to get everything needed from etrailer. I think Optronics is of the highest quality and recommend both etrailer and Optronics product.
Works very well after re-wiring trailer lights with waterproof distribution box.

Hopkins 7-Way RV Style Connector with Molded Cable - Trailer End - 8' Long - RV Standard
7 pin connector separated from cable. I was expecting that "Molded Cable" meant that the connector was fused to the cable insulation but instead, the two separated almost immediately after I installed it. It still works fine as the wires are connected securely inside the connector but with the outer covering pulled out like this, I don't think it will last very long.
Çable good but after putting new 7way plug on truck cable wire colors did not match etrailers picture

Pollak Black Plastic, 7-Pole, RV-Style Trailer Connector - Trailer End
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.
Routine trailer maintenance. Absolutely nothing worse than fighting trailer lighting or electric brake issues when traveling.

7-Way Molded Trailer Wire Connector, 4' Long
When I ordered this harness I thought I was getting a standard 7 way for a conventional trailer with brakes. What I actually got was a harness made for a camper/RV hook up. The wires have all the colors you would expect but all the lights/turn signals are coded into the plug completely different. After spending a good deal of time carefully matching, soldering and heat shrinking all connections to my new trailer harness, I was very dismayed to find only the brakes actually worked. After a bit of research I found a schematics page on the etrailer site and discovered the problem. As this is a molded plug I could not take it apart and just reposition the wires inside the plug. Another full hour or more of rewiring followed and now all is well. The harness itself is of very good quality but was not labeled/identified properly. This could have been prevented if etrailer would clearly label this harness as a camper/RV harness only.
This is definitely a good quality molded cord for the money. Route and wire this cord into a good quality junction box and you will be on your way to having some excellent trailer wiring.

7-Way Molded Trailer Wire Connector, 6' Long
Only gave 4 stars because it was a bit confusing. I have a lot of auto wiring experience; from car stereos,amplifiers and all manner of accessories. All of the info on etrailer indicated that the color coding didn't match up. So I went into it disregarding the standard color coding, when in fact it was just as it should be.
Good thick rubber and plug works perfectly.

7-Way Molded Trailer Wire Connector - 3' Long
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.
After a year doing its job well.

20 Ft 4-Way Trailer Wiring Harness - Wishbone Style - 30" Ground
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.

Wesbar 4-Pole Flat Connector w/ Jacketed Cable - Trailer End - 14' Long
I rewired my boat trailer using the wesbar 4-flat connector from junction box to the hitch. I do wish the wesbar connector was available in tinned wire. I used tinned 14 ga tinned wire for the rest of the wire and ran a ground wire to every light eliminating the trailer frame as a ground. Also added a switch at junction box for a manual trailer reverse flood lights. Filled the junction box with removable potting Gel to prevent water/corrosion. Works great. No issues. Never been stuck on the side of the road troubleshooting an electrical issue / bad ground. Would purchase this again, unless I could find a marine/tinned wire version, then I would purchase that one instead.
We installed this cord on a tilt bed trailer that we use to transport scissor lifts. We have multiple trucks that pull this trailer and the receptacle on these trucks are in different locations. This required using a 4 flat extension on many of them and as you would expect, the extensions come up missing and of course no one knows what happened to them. We tried every trailer supply store in the Phoenix area and no one carries a cord like this. Because this one is 14' long, we can cut off what we don't need and wire it into the J-box on the trailer and make it long enough that we don't need an extension. Great product.

Wesbar 4-Pole Flat Connector w/ Jacketed Cable - Trailer End - 8' Long
Really quality piece. Plenty of length to connect back to the rest of my utility trailer wiring that was still in good shape since it was in an area subject to far less abuse. Nothing worse than having to fix the corroded wires in between replacing the worn out plug every few years. This should give me years maintenance free service even with the toll winter takes.
This is the 2nd one of these I have purchased. They are a good product (therefore the 2nd purchase) but have a few areas that could be improved. 1) In cold northern winters (MN -10 F), the cable gets very stiff, because of the lack of flex, my trailer connection pulled out when turning, dragged on the ground and ground down the plug. 2) the connection where the cable jacket meets the plug separated (again, due to cold weather?). Even though I would prefer a more temperature-forgiving flexible cable, I believe this design is better than the other 4-flat trailer-end wiring harnesses currently available. I also purchased a Hopkins Endurance Quick-Fix Replacement 4-Way Flat Trailer Connector w LED Test Lights - Trailer End to as a quick fix to this cable to temporarily fix my trailer wiring until permanent repairs can be done.

Hopkins Endurance Quick-Fix Replacement 4-Way Flat Trailer Connector w LED Test Lights - Trailer End
Nice product & good value imo--it's very beefy and appears to be heavy duty---I know these are supposed to be temporary---that said this one replaced a Reese connector connector exact same style w/LEDs that was almost 17 years old before it failed--hopefully this lasts even close to that amount of time--I don't use this trailer daily usually not even weekly---so maybe with commercial trailer use this connector isn't for you..... It's my considered opinion that many of the fails are the result of a lousy install or someone disconnecting by pulling on the harness INSTEAD of grabbing the connector either way this gets an A+ from me
This is perfect. I needed an easy way to change the connector on the trailer I'm working on. It was an old pop up camper with an 8 pin connector mounted on the frame. but I only needed a 4 after rewiring it. So, out with the old and in with the new! Plus it's really easy to connect all the wires. Picture is not of the new connector but of the whole project I'm working on. I've since mounted all the running lights, tail lights etc.
