Best 2008 Chevrolet Avalanche Trailer Wirings

Çable good but after putting new 7way plug on truck cable wire colors did not match etrailers picture

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.

A man cannot have too many adapters and this is no exception.

Once again eTrailer has come through with flying colors....fast delivery and exceptional products! If you are doing business elsewhere, you are doing yourself an injustice!

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.

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.

Works well definately like the led test lights. I was not sure when I ordered this that it was the plug or the wiring to the truck it. With the test lights i found the wiring for the truck was just fine and it was my old plug the side that connects to the trailer that was bad. I would highly recommend this product.

ETrailer had exactly what I wanted at a fair price. Website was easy to navigate and purchasing was simple. Shipping was fast and I was kept notified right up to when I received my order.

Fantastic product. Solid construction and durable. I have both a horse trailer and an utility trailer. Makes it so much easier.

Folks were very helpful . product was as shown. found one here local but for 2 bucks more so cant complain. will be using again. Thanks ET

Nice product. Kind of a sloppy fit for my factory 2005 Avalanche hitch though. The 7 pin connector doesn't pin out correct but the 4 pin does so I'll go with that.

It was exactly what it said it was. Perfect replacement.

Didn't use it, because it's a replacement for my truck, that doesn't need replacing yet. Wanted a connector for the MH and this woundn't work, will save for later use.

Excellent replacement!

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.

I was very surprised bt the next day delivery! little did I know you have a warehouse just miles from me. The part was the exact part, came with hardware and snapped onto the harness on our Motorhome, One and done.

Product has worked well. I like the way the cover opens really wide so it's easy to line up the plug. I installed it on my F-350 on a Ranch Hand rear bumber. The four screw holes holes ranch hand drilled for the screws where slightly off from the holes in your product so I had to rotate connector CCW and drill and tap four new holes.

Love the flexibility of the cord in cold weather. But where the cord connects to the plug, that has seperated. Still working, but do not know how long it will last.

The bargman 7 way moulded trailer end is a high quality unit. I have been using it for a year now and it has performed flawlessly. The sturdy moulded plug ensures no moisture can get inside. Both the insulation of the individual wires and also the outer sheath are made of silicone and remain flexible even at canadian winter temperatures. There is just one way I think the unit could be improved. The outer blue silicone coating is thin, and not very abrasion resistant. If it contacts the grouns at all, it will quickly wear through. Just a little thicker sheath would be nice. Overall I am very happy with my purchase, and would certainly purchase again

This product works as expected. There is not too much to the installation, just plug it in properly and mount the ground wire. I did not find an easy way to mount this to my wife's Odyssey, or to the trailer hitch (item# 75270). Luckily, I do prototype design and manufacturing. So I came up with my own solution. I designed and made my own bracket to mount the 7 pole to the trailer hitch. It works like a charm, and looks great!

i had to replace these two items as my dear daughter went down our goat path driveway too fast. they replaced the originals from etrailer from the prior year. shipping is timely and customer service actually helps! i wired from battery to controller to hitch myself, and everything fit.

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.

I received this item in a plastic bag, for a few moments i wondered if it was a knock-off. I had done my home work and was sure that this item would be compatible with the socket on my John Deere 2013 5085M at the time I ordered it, not so. The 'holding ridge' at the plug-in end was not in the right position when fully inserted into the plug on the tractor. I sent multiple pictures to Pollack Technical Support but they were unable to assist me. I finally modified the item myself (something I really hate to do) so that it would fit the plug-in and be 'grasped' by the cover/holder on the tractor side. As I anticipated, the thickness of the plastic was inadequate to make the adaptation 'sweet', so I had to cover the resulting hole with silicone caulk.

This is a great solution for adapting RV blade connector to 6 pole connector. I give it 5 stars. I use this for work purposes, and have found one issue that I DON'T believe to be manufacturer defect. In my industry we use different trucks and trailers daily, if not hourly. Some trailer electric brakes will lock up when adapter is connected. I have found the red wire in the adapter to be the problem. My solution was to splice in a switch so that when the intermittent problem arises I can flip the switch and be on my way.

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.

Your sales staff is second to none. Keep up the good work. You shipped minutes after I placed my order! Very impressed! Marty

The product that you delivered was exactly what I ordered and was received without any problems. Thank you for your great service and products

Promising product with the terrible customer service. Order arrived damaged so the customer service initially promised the full replacement which never happened. After the delayed communication the customer service decided to process it under the warranty claim which never happened. Never recommend to do business with this company again.

Works, exact fit, high quality, coils tight so max of about 3.5’ perfect! Heavy duty wiring, great waterproof connections.

Item was just as I anticipated. It looks good, works great, and the delivery was as promised. E Trailer is a good place to do business.

Good solid unit that I expect to last a lifetime. I purchased this unit primarily to provide a charging port for a float charger. The idea being that if I forget about it or if someone else drives my truck and is unaware that it is connected, it will easily disconnect when the vehicle is driven away.

Perfect! I use the 4 flat for my boat trailer lights and the +12v I've wired to charge the boat battery as I drive to and from where ever I'm fishing; brilliant!

Service was great and the wiring harness was just what I needed. It even arrivide a day early. Thanks.

Fast and exactly as promised. Will order from them again.

fits the plug perfect....just got a goldwing used, haven't had a chance to ensure it (the bike) was wired correctly for a trailer. no fault of the product, just wish its wireing was a bit long due to the way the plug was intigrated into the underside of the tour trunk.

Works great! Took a few minutes to figure out the rv side and get it set up so the round RV part Correlated in the correct way to the standard four flat wiring. But it went smoothly.
