The videos and help were invaluable in connecting all of the wires for the power and brake control. The video was even on the exact model that I was putting the connector on. There are three difficult procedures in the installation. 1) Getting a connection to the brake light under the dash is very difficult as there is very little room. I would have liked to see how the tech was able to determine which wire was the correct one to use and extend it in order to make a splice. I removed the brake switch from the bracket which allowed me to pull it down enough to test each wire and find the one that went live with the brake pedal being used. 2) Making a hole in the firewall to pass power, ground and the brake control wire. Here the video was spot on. The difficulty is that the firewall is about 12" behind the ducting on the engine side and there is not much room inside to work. I used a 24" 1/4 drill from the engine side to start a hole in a good place. Using a drill from the inside the hole was than enlarged to what was needed. 3) Routing the wire from the engine to the back. Here the video did not go into detail as to how the fish the wire through and over the various components. Having a high lift would definitely help here. The remaining connection and wiring was straight forward. I used expandable braided shielding on all of the wires to bundle them together and add additional abrasion resistance. As an added safety measure, inexpensive rubber boots were used to cover the exposed connections on the breakers. Without the boot, the studs would be exposed even with the engine covers in place. 647400

This product is good but has a few problems preventing it from being great. First it doesn’t include the screws and washers that you need to actually connect it to your hitch. Second and the most important factor is that the kit barely has enough wire to hook up a small SUV let alone a mid or full size one. Save yourself some headaches and buy a new set of wire before you even start. The wire came up feet short in my Kia Sorento but only figured this out after running it all the way to the engine to have it stop. 670202

Had to modify for my 2017 Wrangler JKU. Muffler is too close to bumper frame, so had to mount the bracket to the edge so wires would clear heat of muffler. Bumper bottom is not flush with frame. Could not open 7-pin connector cover all the way, had to mount it sideways. So I had to drill new holes in mounting bracket. There is not enough wire to properly route. Had to add 4 feet. 638383

Nice kit overall. The dust cover is a little flimsy. Had to re-drill the holes to make the bracket fit. Had to run separate wires for electric brakes for my truck (not E-trailer’s fault). I was very well pleased with the kit for the price. 903950

Today I installed: - Draw-Tite Max-Frame Trailer Hitch Receiver (Item #76156) - Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector (Item #C56217) - 7-Way RV Upgrade Kit for Trailer Brake Controller Installation - 12 Gauge Wires (Item #ETBC7L) It took about 4 hrs at an amateur pace with manual tools. This is the second time I put a trailer hitch receiver on a Toyota Highlander. My first installation was a Curt on a 2010 Highlander. This time I got the Draw-Tite for my 2018 Highlander. Few observations: - The fact that the car comes pre-wired and with welded nuts for the hitch makes the installation smooth and easy. Nicely done by Toyota. - The Draw-Tite hitch receiver is NOT designed for use with weight distributing hitch, which may be an issue for some users. - I like the that the hitch is nicely hidden under the rear bumper and comes with the bracket for trailer electric connector. Keeps things nice and tidy. - The installation can be done by one person (with the aid of a couple of plastic buckets), but I STRONGLY recommend to have a helper. The hitch receiver is heavy and if you drop it can cause some serious damage to your body. - There is no need to remove the passenger side plastic mud cover behind the rear wheel. - There is a good reason why they don't show you the cutting and installation of the driver side mud cover in the etrailer videos. It's the proverbial PITA. :-) - The receiver ends-up about 16" from the ground (with the car unloaded), so you will need a 2-3" rise ball mount to end around 17-18" once the trailer is hooked up. - The cables can be routed nicely through an existing hole under the driver side plastic storage bin. It comes with a rubber plug which can be cut just enough to lush the connector through. This is the cable routing for OEM Toyota trailer cables. And because is it hidden under the plastic mud cover, you don't have to worry water getting in when driving on a rainy day. - Make sure to protect the cables with a plastic hose or by wrapping them with plenty of insulating tape to prevent chaffing in the places where the cables cross hitch members. Some edges can be sharp and sooner or later will cut through the insulation. - Trailer wiring and the T-connector are power all the time, regardless of if the key is in the ignition or not. So make sure to unplug your trailer when parked for extended period of time to prevent running down the battery. The T-connector itself draws only about 1 mA when idle, so you don't have to worry as long as the trailer is not connected. - The fact that you can see the hitch with the rear view camera makes hooking up the trailer a breeze by just person. Overall, I'm happy with the product. And etrailer customer services and prompt shipping was, as always, 5-stars. (I am a returning customer) 903111

This is exactly what I needed to upgrade the 4-pin connection to a 7-pin connection on my 2020 Subaru Outback with Subaru hitch. It's the second time I've had one of these kits installed on a vehicle (previously had it on a 2009 Subaru Forester) & the electrical guy at the mechanic's shop knew exactly what to do. 901626

All the parts were in one place to add a 7-way connection for my 2020 Highlander, but sadly the very visible screws which hold the 7-pin plug outlet rusted within two days of the installation. I used care when putting them in and am disappointed to see that I'll need to back them out and paint. 896113

Installed easily enough into my 2020 Subaru Outback- installed the same time I put the hitch in- plenty of room in the tire storage area for the excess cable. My teardrop's brakes are working just fine and it's nice to still have the 4 pin! 884297

Great product and looks sleek. I installed on my 2020 Subaru Outback Touring XT and attached to my factory installed hitch. With a vice and hammer, I had to bend the supplied bracket straight for the correct mount orientation; it turned out great though! I gave 4 ??'s because of several factors: 1) After taking a bit of time routing the 12 awg wire to the battery, I could have used a foot or two more wire; my car isn't even that long, and I took a pretty direct route. I even measured and preplanned, thinking I'd be fine. Had to use some spare 12 awg wire I had on hand. 2) As another reviewer stated, I was having problems with the 4-pin sliding out of the bracket. But, I fixed the problem by tying one of the supplied zip-ties around the rubber 4-pin edge and two of the bracket screws, which now holds it in place. 3) It would have been nice to have a set of screws and nuts to attach the bracket to the hitch; I just utilized the existing ones from my 4-pin factory installed bracket. All in all, I'm really happy with this product! 866081

Pretty simple to install, and it’s been great for a year. Only wish I had a little more ground clearance. Where I mounted the wiring harness receiver should have been a little higher, but I can’t fault the MFG for that. 851906

Worked very well the minute we set it up and got it paired. It was hard to tell if the trailer was responding since it appeared to pull and stop very evenly from the very beginning. I used the ETBC7L 4 pin flat to 7 pin converter kit. I connected the black power cable to the battery and hooked up the ground and BINGO it worked. It was a lot of work to get the black power feed cable from the controller to the battery but once it was all connected the controller just plugged right into the 7 pin adapter and the trailer plugged into the controller. I did have issues with it losing connectivity to my phone but that didn't seem to stop it from working. Great service from the folks at trailer. I paid for two day shipping and it arrived in two days in great condition. I bought the controller and the 4 pin to 7 pin converter kit together. 814484

I regret buying this. There were a few missing pieces when it arrived and furthermore, what they don’t tell you, is that this harness has a power cable that goes directly to the battery. If you have a trailer and don’t completely undo the connection after you turn your car off, the lights will stay on and it will drain your battery. It should have came with the extra $40 part they try to sell you after the install. Surprise!!!!! If you want a dead battery, buy this harness. If you want it to work the way it should, plan on buying an additional $40 part. Pretty pitiful and misleading If you ask me. 805244

  • Which 4-Way to 7-Way Trailer Wiring Adapter Allows Trailer Battery Charge Circuit to Activate
    Since your plan is to install a brake controller and want to charge the camper battery what you need is actually the part # ETBC7. This comes with basically the same things as the # ETBC7L except it also includes wiring and circuit breaker to complete the brake controller circuit that you use for charging the trailer battery. I attached a video that shows this kit installed on a similar 2011 Subaru Outback for you to check out as well. The brake controller in the video is our best selling...

    I suggest using the 7-Way RV Upgrade Kit part # ETBC7L and the Curt Echo part # C51180 because of the ease of installation and convenience. The Curt Echo Mobile Trailer Brake Controller just needs the basic trailer lighting functions and 12V power to be fully operational. Just wire the 12V black wire from ETBC7L to the vehicle's battery via the circuit breaker, ground the white wire and connect the 4 pin to the 4 pin portion of the plug shown in the picture I attached.

  • Why Does Black Wire of ETBC7L Run to Vehicle Battery
    If you have a power wire ran to your current 4-way wiring it's to power the taillights of your trailer from the battery instead of your vehicle taillights.

I attached a review video for this for more info on this kit as well.

  • Could 12 Volt Wire for Trailer Wiring Also be Used to Power Circuit of Curt Echo Brake Controller
    The power wire of the # 119250KIT would not be rated high enough to carry enough amperage for both the # 119250KIT and the Echo part # C51180. So what you'd want to do is run the wire that comes with the # ETBC7L along the same routing to get the the vehicle battery and you'd be set. This also prevents a short in the trailer wiring from potentially shorting out the brake controller and damaging it since they will be on separate circuits.

  • Will Curt C51108 Echo Pass Through 12-Volt Power to Maintain Trailer Mounted Battery
    The 12-volt power circuit on the trailer connector provides the power for the brake controller which can use up to 10 amps per axle. The controller will 'pass through' the 12 volt power feed circuit to the trailer but it won't have too much effect during braking as the entire feed circuit only provides up to 30 amps. The # C51180 Echo needs that direct connection to the car battery in order to function and actuate your trailer brakes. In other words, I wouldn't depend on the 12-volt...
