Installation
This custom-fit T-connector plugs into your vehicle's wiring harness, which is located in your rear cargo area. You will have to remove interior trim paneling to access the connection point. Once you've plugged in the T-connector, insert the included 10-amp fuse into the in-line fuse holder.
Once installation is complete, the 4-way connector will be stowed in an out-of-the-way location within your cargo area.
It is recommended that you use a small amount of grease on all electrical connections - the plug on your automobile and the 4-pole connector itself - to help prevent corrosion.
A tail light converter is built into this T-connector. This converter is a circuit-protected, battery-powered unit that bypasses the electrical routes that are used by a basic wiring harness. As a result, there is virtually no draw on your tail light circuits.
Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are compatible with the wiring system of the trailer. This converter combines the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.
Curt builds each tail light converter using surface-mount technology (SMT). This method of construction involves soldering electronic components directly to the surface of a printed circuit board. SMT eliminates the need for leads, which are used in older through-hole technology. The result is a circuit board that is smaller yet provides more routing area and that offers superior performance, reliability and durability.
Circuit boards constructed using SMT have been shown to perform better under rough conditions with excessive vibration than those made using the through-hole method. And where would vibration be more likely to occur than in towing applications? Curt converters also produce less heat, leading to increased durability and longer life. In addition, lower levels of resistance ensure better performance, especially for parts that operate at higher frequencies.
Each Curt circuit board is made using high-quality components that are pieced together in the most technologically savvy fashion, leading to greater predictability and reliability in functioning.

Today we are going to be taking a look at the Curt T-connector vehicle wiring harness with a four pull flat trailer connector. It's part number is C55370. This product is going to fit certain years and models of the Subaru Tribeca, Forester, Outback Wagon and Legacy. It's going to provide your 4-way flat trailer connector at the back of your vehicle and empower your trailer's signal lights. This is compatible with 5-pull, 6-pull and 7-pull adapters. Those adapters are sold separately.
The benefit of a system like this is it's designed to connect quickly and easily, you do not have to worry about cutting or splicing any wires. All you have to do is locate the connection point in your rear cargo area, follow the instructions these are very detailed they are going to tell you exactly where that connection point's located. Once you've found that connection point simply just plug in your connector, the connectors are going to perfectly fit together. They are going to snap lock for a nice tight secure fit. Once you have that connected your going to see here the red wire has a fuse holder box included. And it's going to come with a 10amp fuse so you would simply plug in the connector and install the included 10amp fuse inside the fuse holder right there and close over the protective cap for that fuse. Once your install is complete the connector- talking about the 4-way flat connector is going to be stowed in an out of a way location within your rear cargo area. The black box right here this is going to be your tail light converter, it's going to insure that your vehicles wiring matches that of your trailers. Now the powered modules going to connect directly to the battery through the wiring to avoid overloading the vehicles electrical system.
It's constructed using surface mount technology for consistent reliable performance. What that means is it's going to maximize your trailer light yield and intensity while producing minimal heat. It's also going to insure superior operation even in rough road conditions. You see here we've got plenty of wiring, that's all bundled up for the 4-way flat connector that way we can extend the connector out the back of the vehicle and make our connections as necessary. But here on the connector itself it's going to have a 4-way flat dust cap that way we can protect our connection points when our connector is not being used. The maximum amperage for the stop and turn lights is going to be 3amps per circuit. And for the tail lights we're looking at 6amps per circuit.
Were always going to recommend that you use a small amount of dielectric grease on all electrical connections to help prevent an corrosion for being able to settle in. If you don't have any of that dielectric grease you can find that here on our website as well it's going to be sold separately. But again with this part number you're going to get everything you need for a full insulation including the 10amp fuse, you're going to get detailed instructions, you're going to get some double sided adhesive tape that way you can mount your tail light converter to a nice clean out of the way location. And your going to get some zip ties that way you can secure any excess or slack in the wiring that you may have, makes for an overall cleaner appearance for your installation. That's going to do it for today's review of part number C55370. This is the Curt T-connector vehicles wiring harness with the 4-pull flat trailer connector.

Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. Connector plugs directly into existing wiring. Powered converter reduces strain on wiring system and is made using SMT to ensure superior performance.I'll start off and say that this product looks and feels five star, but I'm docking it one because the installation docs and video are very mismatched and conflictive. The one-page paper installation doc was barely applicable, while the video was much, much better. Use it! Pulling out the few pieces of the car necessary to gain access to the OEM plug was relatively easy. Where things got messy was where to actually put the "control" block for this thing. The video shows a self-adhesive backing which was not present. There are included zip-ties but no really good place to use them. I didn't want to leave it loose in there to become yet another rattle in the car, so I ended up securing it with that foil tape used for duct-work. It seems to have done the trick. Routing the cable was easy, and I dropped it under the spare tire and through a grommet, resealing it with silicone when I was done. I'd have loved to see some kind of cable management included for under the car and around the hitch, rather than the four independent wires being just ad-hoc wrapped around things. Electrical testing worked flawlessly, and all outputs were signaling correctly. 529224
Great product. This took under 5 minutes to install. The Forester 2006 had the electrical connector under the floor tray on the passenger side at the very rear under the taillight hidden by a plastic flap. Lift up flap, plug in, then snug the hardware into the side well. You can run the wire and trailer connector through the 1" hole at the rear of the wheel well capped by a large rubber plug so the wire disappears under the spare. 94920
The product works but it is always drawing power. I need to unplug it from the cars wiring harness when I do not have a trailer attached. (the plug connecting the "circuit box" to the cars wiring harness.) At night when the car is parked (completely turned off) and a trailer hooked up to the wiring, you can see the tail lights glowing with a faint light. This should not happen. This is a replacement harness for one that I left plugged into the car all the time. It stopped working unexpectedly and I had to order a replacement. The circuit box had swelled probably by 10% to 15% in size. It happened after warranty so I paid for it hoping that it was a fluke. I would not order this product again. 259312

Super easy to install, truly plug and p lay. 756303
Great customer service, very knowledgeable and go out of their way to help! They also have great DIY product comparison and installation videos. 746304
Very easy to install once I watched the Youtube Video on installation. Much easier to install than the Harness on my 2016 Outback. I will look forward to testing this in the Spring when I begin to tow my Utility Trailer for yard work! 737793
Great product 736797
I purchased a trailering wire harness for my Subaru forester . Installation was a breeze and work perfect. 726254
Worked perfectly with my 2002 Outback wagon and Uhaul trailers. On this model, the harness attachment is found in the back underneath the carpeting and foam over the passenger side wheel well. 725238
Received my trailer harness this afternoon from etrailer and had it installed in my B9 Tribeca in 15min (incl. Opening the box and walking out to the car). The harness worked perfectly as promised. The only thing I would warn anyone about it that when you plug your harness in and it doesn't work check the fuse holder that's part of the harness. My fuse wasn't in there, after I put the supplied fuse in everything worked great. That was so freakin easy compared to the way I used to do it, get out the tester, lay under the car for 2 hours on my back. BUY IT, it works so easy! Oh the quality of the harness is really good. It was made professionally, everythings water tight and ready for your trailer pulling. Happy towing 724671

This is an excellent product. I have installed the the trailer wiring harness, the instructions were clear and concise and the installation took about 10 minutes. I hope to install the hitch tomorrow. I reviewed the instructions for that installation and looked under my Subaru. The hitch installation should take an hour or so and I'm slow. Again, excellent product and clear instructions. If you need a hitch for your Subaru, this is the way to go. 705303
After having the car wired at a national trailer rental company,, incorrectly!! I tried to figure out what was wrong for several hours. Purchased the CORRECT connector from etrailer for a fraction of the cost, followed their installation video and 10 minutes later eureka!!! 698120
Easy to install 696877
Plug and play perfect. 696332
Wiring harness plugged in and works great. Plenty long enough to use on any trailer. 691287
The receiver for my 2006 Subaru Forester arrived quickly. Installation was straightforward and pleasant, especially with the video tutorial links. A bit off-putting to slam the hatchback on to the trailer wiring, but as advertised, it hasn't hurt the wires yet, and the hitch has seen plenty of action since installation last year. You all sell a well-made product, and your promptness and service have been top-par. Thank you for that. Pat yourselves on the back! 691610
Everything fit and it plugged right in to my vehicle wiring harness 688604
excellent thanks. 681047
The ball mount, ball, hitch pin and light kit are still working well after a year. 677968
