Most Popular Plug Only for 2013 GMC Terrain

Works great and etrailer folks did an outstanding job with quick turnaround and communication…thank you!

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.

This product has been great. I purchased the multi-pin trailer wiring kit, and 4-pin adapter plug. By also purchasing the vehicles specific wiring harness, instalation was quick and easy! I chose to mount this through my bumber, instead of using the included bracket for a more factory finished look, and to avoud ripping off the mount while on rought terrain. This system works great and is much more affordable than factory parts. I highly recommend!

I wanted one with a LED tester built into it to "trick" my SUV into thinking I had a trailer connected when really it was just a bike rack so the car didn't slam in it's brakes while reversing thinking it was something else. So I bought a different adapter. The picture slightly deceived me into thinking this had LED tester because the plug is attached by a rubber string (that I thought was a wire). So add another picture of the other side and that would eliminate my confusion. 4 stars because it probably works the way 99% of people would want to use it for.

Seems to be a well made product that should make it easily replaceable for me. The usual excellent delivery and service from etrailer that I have come to expect.

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

Well I wasn't able to use this as there was no good place to install on my car without it practically dragging. Not a product problem at all. I tried to return and customer service was fast and super helpful... unfortunately return shipping would eat up any refund. So.. I get to keep it. good quality and product. Very happy with it and wish I could use it. Will keep it for sometime in the future when of course I will need it.

I bought this socket for my 2006 Volvo Xc90 to wire in the 4-Pole harness I also purchased from etrailer. Already had a few 7 Blade to 4-Pole adapters from my previous vehicle, and wanted the option of adding a trailer brake wire for a small camper later on so that was the main reason for the purchase. It also went very well with the Hidden Hitch I had already installed, bracket mounted right up to the existing tabs on the hitch. Super quick and easy install, as all of my etrailer purchases have been. Looks great on the truck, and functions great with the 180 Degree cover.

We just finished a makeover of our 1995 boat trailer. New bunks, sanded and painted but the best part of the project was the new LED lights from your company. They are so much brighter than the old incandescent bulbs that you really do feel safer driving down the road. We pulled the 20 year old wire out and replaced with new and used the 3M scotch loks to tie in. We were not sure the new style grommets would fit the old holes in the frame but they fit great. Your customer service was great, alerting me to a backordered reflector but recommended a replacement that worked fine. Patrick set up a Q&A page for me since I had questions about the best way to protect connections with dielectric grease, heat shrink and tape. Your website is one of the best with ease of navigation, complete pictures, great selection and thorough info, dimensions, etc. You guys really have your act together and also offer great value. I would not hesitate to purchase again and will recommend you when I can. I have attached a couple of pictures. Thanks for all your help. Wayne N.

Easy to install and works great.

I found what I thought I needed on the website to prepare our car to be flat towed, but wanted to call to verify. After a short phone call, eTrailer saved me about $50 and got me the stuff I actually needed to get the job done! I won’t shop anywhere else!

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.

Used this as the connection point for the Roadmaster diode wiring kit. Seems to be well made and will hopefully last a long time. I did spray paint it flat black so it blends into the front bumper of my “toad” a little better.

The documentation for wiring is limited and difficult to read without magnification. Otherwise this is well made and works perfectly.

great product

The plastic plugs don’t hold up very well in the bed of the truck to plug in the 5th wheel trailer in nothing can beat the metal ones

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.

This is not a real easy thing for do it yourselfer. However with the resources provided, if you are ok using tools and are able to watch a video showing step by step you and can do this. The base plate and towing system has been perfect.

Worried as first because the picture with instruction showed an adapter and I had a curved surface on my GMC Terrain at the mounting point. Worked great and did not een have to take the ld pigtail off.

Products were shipped same day I ordered, received parts whitin 3 days of ordering. Parts were exactly what I had been looking for.

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.

Plugs in easily, shows that pins are producing voltage, and locks in place using the spring loaded door to the 7-pin.

Excellent Quick Delivery When you are driving a Test or NASCAR Hauler you need replacement parts very quick, just like a pit stop. Thank You very much for the rapid delivery. Mint Moore III Ford Performance Race Hauler Driver

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

I never used it. It does not fit my motorhome. Still sitting in my garage.

Perfect fit with easy installation instructions!

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.

After a year this connector is still working fine. No complaints.

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.
