Most Popular Wiring for 2021 Ford F-150

The Tekonsha Prodigy P3 brake controller was a much needed upgrade for my truck. I had an older basic brake controller that I used with my small camper that we had and it faired well at the time. But…with a 38’ camper that’s double the weight the Prodigy 3 is a perfect match. Towing is less stressful now with confidence in brake situations. Also the model specific harness I purchased with it made the installation quick and painless. Thank you etrailer for another great product

Easy plug and play for our 2016 Explorer Sport w/ tow package. Nice quality cable.

This product is 98% plug and play. The only issues we ran into was the supplied harness ground wire we installed to the bed frame didn't provide a ground through the truck. Most likely was the bed mounting isolators were preventing a good connection. We ran an additional ground wire from the mentioned harness ground to the mounting bolt of the 7-way connector mounted to the bumper. We also had to run a dedicated 12 volt fused power wire to the 7-way connector from the battery to operate our electric trailer jack.

This is my third truck using my prodigy brake controller with the plug in adapter. As in the past the wiring is heavy gauge to match vehicle & installed with ease. I used the prodigy mount bracket to take up space & slid it in factory controller slot. I can unplug it when not in use if I want & interior looks stock. I make a slot in back of dash compartment to feed adapter wire through for easy plug in & out. Product was revived quickly & ordering on etrailer site was a breeze. Would definitely recommend this plug & play adapter

The Curt wiring adapter was fine, however our coach was not wired with a plug in the harness, so installation required a little wiring work to complete. No big issue, the product was great

Everything was as described. Easy easy installation in 10 minutes. Not the top of the line controller but it's all I need. Very fast shipping as well. Couldn't be more happy with etrailer. I will be purchasing my fifth through etrailer soon!

Adapted Curt brake controller for my 2014 Ford F150 STX without any problems. Just find your Ford brake control connector behind the coin slot on the left side of the dash and plug it in.

Exactly what I paid for with fast shipping at a good price. Everything looks great and works perfectly.

The product itself is great, but the hardware (screws, nuts, etc) is trash. Should be stainless steel. Keep in mind, it doesn't include hardware to fasten to the frame of your vehicle. I used the hardware from another kit here on etrailer. I initially ordered the incorrect bracket. I had it installed for literally one week. No snow or ice, and it looks like I dropped the thing in the ocean for a month.

Gotta have this bracket to mount your 7 pole connector to. But I had a place to attach to on my Draw-Tite hitch and didn't need the self tapping screws, HOWEVER, I needed two additional black screws to attach the connector bracket to the hitch spot. Should come with (6) black screws and two self tappers. I have to go find two additional black screws if able to attach the bracket to the hitch hangar. That's why i didn't give it five stars.

Installed this Junction Box while repairing some previously installed sketchy wiring. Having access to these wires made a ground issue we were having very easy to diagnose. Very good product.

I mounted mine onto a piece of aluminum flat stock on the trailer “A” frame to reduce rock impact from Nevada’s gravel back roads. There really wasn’t good location on inside of trailer frame rails, was adding electric brakes and converting from 4 pin to seven. . I’m pretty darn happy with this junction box as it made rewiring rather straight forward. Our local 12 volt guru at the auto electric shop was duly impressed-wanted to know where I found it.

Connector bundle easy to install & worked great. Although the instructions say to feed the bed connector from the bottom it seemed easier to feed the bumper connectors from the upper the bed connector hole

Does what it needs to do for trailer plug connections.

Plugged right into my 2019 f150 so I could use my old brake controller

Installation photo

hitch installation video was helpful... bolt clearances on the passenger side above the muffler were very tight the space saver spare barely clears the hitch. The wiring harness 7 pin mounting only bolts to the plastic valance. There is no room for any other type of mounting.

Thanks for the great video on installing the 7 pin adapter (ETBC7L). The video was even on a Toyota Grand Highlander - my exact vehicle. I didn't like how low the video installed the bracket, so I made a few bends to this bracket to integrate it more into the the lower molding. This raised it up another inch or so compared to your video. You can see the height difference in the screen grabs of your install versus mine. Bottom line, you can use this bracket to fabricate for you unique situation.

Fits perfectly. Uses the existing bracket mount on the hitch (Sprinter passenger van version)

Nice piece but I am now aware that this bracket wasn't compatible with the 7-way kit I installed. I made it work by drilling more holes but be aware, not all brackets work with all 7-way plugs.

Good product, easy installation, manual showings step by step,

Worked out perfect for my 2024 Kia Sorento Prestige, I could not find a harness that would directly plug into the factory tow harness. My only complaint was the length of wire to plug into the passenger taillight was about six inches too short.

It's a well built piece of hardware, that fits the Hopkins plug. Unfortunately it does not fit my trucks bumper. No matter how I tried to line it up it wasn't going to work with my truck's bumper.

Proper fit for the Ford wiring harness end Teri Al.

Looks good!

Pigtail worked as expected with mating rv 7 blade socket. Easy for replacement of existing parts.

My package didn’t come with the mounting screws but I still got it mounted securely using two self-tapping screws I had available. I drilled them into the plastic surround near the vehicle bumper, and it worked just fine

I purchased this item with my trailer hitch. This product is very sturdy, easy to install and made of good strong material. My 4-way plug fits perfectly and is held tightly by the bracket, also it came with bolts and nuts to secure bracket to the hitch.
