Trailer plug receptacle recommendation

[BWSwede]

Hello all,

I have had my trailer pigtail lose its electrical connection from my truck twice in the past year. Both times I lost my trailer brakes with a full load on the trailer. Each time I narrowly avoided an accident due to my inability to stop.

Does anyone have a recommendation for a 7 blade receptacle to replace the one on my truck? Or all they all more or less the same?

TIA,
Blane

My truck has a light on each side of the license plate. I enlarged the hole for one of them and mounted the receptacle there. In it's thirty years it's never been a problem.

Go to etrailers.com and read the reviews. Most all the name brands will work for you. And I've had very good experience ordering from them.

I'd 2nd that. There won't be a lot of difference, but some of the covers & plastic will be a bit more sturdy. Etrailer has good info.

I'd get one that has the 7 pin & 4 pin connectors on it. Handy to not need an adapter when towing small.

Hello all,

Thank you for your replies and recommendation to use ETrailer. I could not find a 7 blade plug with the two pigtails and plugs to connect to my truck's wiring. It turns out it is made anymore. The best they could offer is a plug with screw connections for the connectin of bare wires from the truck. I really didn't want to crawl under there and start rewiring the trailer plug so I looked to see what the problem might be. I found that the pigtail coming from the trailer had gray type powdery corrosion on the contacts so I took an emory board and sanded the corrosion off. I also went to the truck plug and did the same thing there. Hopefully this cures my problem.

Thanks again,
Blane

That will probably fix it for awhile, but I doubt it will last long before you have to do it again. Use some dielectric grease to help reduce the corrosion.

not sure what truck you have.
is it a factory plug?

Curt has a decent line of replacement plugs.
So why is it falling out?
Is the latch on the cover not holding it in place?
is the plug not going into the receptacle far enough?
Is the plug wire too short pulling itself out?

Never had that issue and I have had a lot of trailers

Here is the full story.

I have a 1 ton pickup with a factory trailer receptacle. I was pulling a will maintained 14k PJ equipment trailer with my tractor on it.

I had been pulling this trailer with this truck for 5 years without a braking issue. Last summer I had my tractor on the trailer (13,450 pounds on the trailer axles per the scales plus of course the tongue weight on the truck) and merged down onto a busy interstate highway during rush hour. I was going about 45 when a car pulled in front of me and put on their brakes. Normally this is not a that big of a deal but this time when I hit the truck brakes and reached down to slide the trailer brake controller lever to further help with the braking there was no response from the trailer brakes. I applied the truck brakes with full force and the front wheels were alternately skidding and then rolling as the trailer rocked forward and back, more so as this action continued. I came within a couple feet of rear ending the car ahead and it scared the living daylights out of me.

About 8 miles later was my first chance to pull onto a shoulder wide enough for the trailer. At that point I saw that the trailer cord was still attached to the truck's receptacle. So I tightened it into place I zip tied the two together. I have been doing this for the last year without issue.

Last week I had just left my house with the loaded trailer and the plug zip tied to the truck's receptacle as I now always do. From my house to the local arterial streets is a 500' elevation drop. A about midway down the hill I noticed my trailer brakes were not responding to my actions on the sliding lever. Once again I found myself with no trailer brakes. Since all I had were the truck brakes they quickly got very hot and started to fade. After not much time I realized there was no way for me to stop the truck and trailer. All I could do was try to control the speed down the hill and hope that no one if front of me stopped. Another white knuckle experience. I got out of the truck once I finally rolled to a stop and saw that the trailer cored was still zip tied to the truck's receptacle. So I cut that tie off and tied it together a little differently and that worked for the rest of the trip.

The cord from the trailer is very long and doesn't even come close to becoming tight at any angle the trailer is from the truck. The trailer cord plug is not damaged at all, and in fact is in really good shape. The truck receptacle or lid is not damaged at all. The spring on the lid is still tight as it should be.

I can't find anything wrong with any of the components except for some of the gray powdery corrosion inside the trailer plug, which has now been cleaned out. I sure hope this solves the issue because I am not sure my heart can take another episode of losing my trailer brakes with my tractor loaded on it.
