Speaker 1: Today we're going to take a look at the Replacement Multi-Plug 7-Way and 4-Way Trailer Connector.Now, this is a custom-fit part. It is designed to fit the 2003 to 2006 Toyota Tundra trucks. This part will give you the ability to tow trailers with the different style trailer connectors. Your vehicle must have the factory 7-way in order for this harness to fit. This'll plug right into the connectors that are on your vehicle. If you notice, the 7-way is in a nice, durable, hard plastic shelf for protection.
This does provide the 7-way connector, has a spring-loaded cap with the seal on it to keep any dirt or grime from getting into the connectors, and it also has this 4-way, which has a nice dust cover over it also to protect the terminals when you're not using it.All this is included that's shown on the table. The mounting bracket and the hardware's all included to install this to your vehicle, and a nice set of detailed instructions.But, basically, all you have to do is take your mounting bracket, slide the cords through there, bring that up. You'll notice the four holes will line up just like that, and then you'll have two at the top that you're going to attach to your vehicle, but also it's nice, you notice there's a cut-out there, and it's made specifically for the 4-way to stick right in there. You just slide your 4-way in there and that'll be at the back of your vehicle. You have access to the 7-way and then the 4-way right over here.But that should do it for the review on the Replacement Multi-Plug 7-Way and 4-Way Trailer Connector..

Tow Ready replacement 7-way flat pin and 4-flat combo adapter harness for vehicles with a factory socket.The connection came deformed and needed considerable work to make it fit the OEM truck side. Packaging was not damaged. This was a manufacturer quality issue. While I got it to eventually work, it was disappointing that it needed so much time and attention to make the connection.
Easy to use site and product came well rapped and on time.
Product over all is a nice unit. Turns out though there is 2 different options for the GX470 and I didn’t realize. Make sure you look to see which one is correct. This one wasn’t the correct one I needed, put in my order for the correct one after realizing. Only way to know is to get under and look at the plugs on your vehicle. This one has one female plug(4pin) and one male plug(3pin) so make sure you are ordering the correct one
Package arrived promptly - as expected - all in good shape. All hardware (screws, bolts etc.) included. I haven't had a chance to install it but am confident it will work just fine.
I replaced the 7-way trailer connector harness with this product. I own a 2005 Tundra. The original connector was damaged when I backed into a rock I didn't see. This product is superior to the stock connector, for several reasons: [a] it also includes a 4-way connector, which increases towing flexibility, [b] overall, it is more robust than the original (in my opinion), and [c] the wire harness is better integrated into the connector, which prevents water and dust intrusion. The wiring harness is shorter than the original, but the end plugs connected [new male to existing female] without issue - although the stock wire bundle holding strap positions could not be used. In fact, based on the fit, I abandoned the holding straps altogether. Contrary to one reviewer, who questioned whether the plugs would remain connected due to the stretch, the plugs snap together. As several other reviewers have mentioned, the bracket holes are misaligned slightly and are too small for the stock bolts. By drilling these holes out with a 5/16 bit, the fit is nearly perfect. The product sheet implies the connector is an add-on [as evidenced by the included self-tapping screws], not a replacement, as advertised. Regardless, this is a quality product that installs easily and quickly for the DIY customer with basic tools. In addition, it saves a bundle of money in avoiding a purchase at a dealership ! ! ! I just checked with my Toyota dealer and they wanted just over $200, and that's with a 10% discount.

Still working exactly as advertised no problems whatsoever ! !
The product was good quality. Loved seeing the install video before purchasing. The only complaint I have is the wiring harness was too short for 2003 Toyota Sequoia. I could not attach the bracket back to the metal where the oem plug was. I had to drill holes into the plastic bumper and barely bypasses the hitch bar.

I had to remove this product and reinstall the old wiring. In all fairness, it may have not worked due to the previous owner messing with the truck wiring. It didn’t work for me. However I would still recommend the product and believe it would work well on an OEM install.

The replacement multi-plug 7-way and 4-pole trailer connector was just as I excepted.
I will always use etrailer for any trailering needs.
Good quick service.

I have a 2004 Toy Tundra 4.7 Quad cab with factory installed tow kit. Want to replace light harness kit as trailer lights are not functioning and man at trailer shop with a tester said no power is coming out of trailer plug on truck to boat wiring.
The product was easy to install. One minor alteration was needed. I had to enlarge both of the mounting holes ever so little. Just a few runs with a small rat tail file did the trick. It is sturdier built than the OEM. All the pigtail wiring was flawless on the product. No more trouble shooting when I switch trailers back and forth. Also, I no longer have to use an adapter when switching between 7way and 4pole wired trailers. HIGHLY RECOMMEND IT.
Looks solidly made with correct connectors.
Bracket fitted existing bracket on frame though the holes on bracket did need to be drilled out to 1/4" to accept existing bolts.
Connectors are correct but the harness is quite a bit shorter than original. The connectors do not have slot for existing cable holder so cannot mount to existing frame cable holder. Check harness not damaged when spare tire removed.
Original had the tabs [Tail lamp, left turn and stop etc.]labeled on the the cover. Would be neat if Tekonsha had a similar molding as it would apply to all its seven connector devices. However could at least add a printed card with a diagram. Takes the guess work out of circuit checking.
Solid product. Harness connectors were spot on. I replaced a factory 7 pin connector. There are two areas for improvement. First, the bracket mounting holes were slightly smaller than stock and had to be drilled out a little. Also, the spacing was off about a 1/16", but the drilling took care of that. 2nd, the harness is about 3 to 4 inches shorter than stock, so the original wire loom holding strap positions could not be used. Otherwise, great connector. The 4 pin flat connector is a great addition!
I received my 2003 Tundra trailer wiring pigtail in short order which is a pleasant surprise. I haven't installed it as yet because I haven't been able to get the old one off as yet. I'm scheduled for an appointment with Toyota for an oil change and they will take the old one off. But I have compared the new one to the old one and it appears to be an identicall fit. Now instead of having a seperate 4-way flat hanging down I'll have one attached to the 6 way plug. My complements on the quality and fit of this item.
Connected to the vehicle wiring harness with no problems. While attaching the base unit to the vehicle, I had to attach it to the bumper which is plastic, so I used a stiffener to the bottom of the bumper. It was easier to pre-drill the stiffener to the unit on the floor for ease of mounting unit to bumper. It was mounted left of the hitch and it looks very good not to say so myself.

I purchased this harness to replace the OEM harness that broke off. The replacement harness was well built and installed easily. I just had to oversize the bracket holes because I was using the original hardware. If the spring loaded cover had a rubber weather seal it would have got a 5 star rating. Great product!
First, let me say, I don't usually write reviews... However, this product rocks. My used Tundra had a broken multi-plug and I was thinking about heading out to a junkyard to get a replacement as Toyota wanted +$150.00 for a new part. I found etrailer online and ordered it. Other than having to drill out the two holes in the bracket that mounts to the bottom of the bumper, the install was flawless and easy (less than 10 minutes). I have already told two friends about etrailer, and I will be shopping here again if/when I need additional trailer accessories.
Works well. One complaint would be that I wish it was a little longer for use with the socket tekonsha mount as my controller stays in the box of the trailer. It is a shared trailer and there is no point to buying two separate controllers.
Product is super but...
It did NOT fit on my 2004 Sequoia without my needing to move the location from the original. After reading the other reviews, I bought it assuming that if I removed the original wire holders, it would stretch and still plug in. Mine did not. My original wires were 24 inches long, these are 12 inches. That is a big difference.
The folks at e-trailer were great but in the end, I did have to relocate my plug.
Please ensure that you check your plugs if you already have a factory 7-pin adapter. I have a 2004 4Runner and after starting the install I discovered the plugs on my vehicle (4 and 3 pin) did not match up properly with the adapter. The four pin plug worked but the 3 pin adapter was incorrect for my vehicle model. The adapter end was exactly the same as the one on my vehicle (I believe male to male connector). I called support and it looks like they make two different wiring configurations. 1 model has the 3pin male and the other model has the 3 pin female.
I spoke with customer service (a nice young lady) and we were able to get the order setup for the right part (HM43374).
Great product! Easy to install and has worked great. My factory wiring harness had shorted out and once I got it off it was on with this one in no time. I really like having both the flat and round plugs so I don't have to worry if I don't have my adaptor for some reason.
This product did the job in replacing the factory wiring harness. I only had to modify the mounting holes spacing slightly by drilling out the holes to accept the original screws. The supplied mounting screws were much less substantial than the originals and did not fit the nuts that held the original harness. The job took about 30 minutes.
Harness was super easy to install. I did tweak the install by using better screws than what were provided for the frame. I used self tapping screws that were much larger. The only troubles I had was unplugging the part on the Truck but the new parts plugged right in. No more round adapters to use anymore.
This harness fixed my problem. The OEM harness got some salt water in it and was causing my trailer lights to not work. The mounting bracket that attaches to my 05 Tundra was a little off but was easy to fix with a drill.
Great product and the built in 4 way is very nice, i don't have to use the 7 Way adapter anymore.
I purchased as replacement wiring for a 2004 sequoia truck. Although the connectors are correct, the wiring is too short. Either you need to change the location of the housing box or add 9 inches of cable. Would not recommend purchase.
Plugs right in. But had to change use bracket that came with but not until drilling screw holes out so i could use factory holes and screws.
the wires coming out are different color and location then standard plugs had to test all before i could hood new trailer wires.
Never used it. My vehicle does not have the same connections as this harness.

This connector isnt a fit for your vehicle, a Toyota FJ Cruiser. its a fit for a 2003-2006 Toyota Tundra.
I backed into something with my old Tundra truck and destroyed the 7-pin trailer connector. Toyota wanted $292 for a replacement! I got this one for about $50 with shipping. It seemed to be high quality and was a plug-and-play replacement. I highly recommend it.
