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. 88968

Here's a first, this "RARE" 1- The young man that answered the phone "TITUS T" actually knew the answers to help me, and was right!. (spoke english) 2-The part came on time as promissed and I recieved e-mail notifications the entire time as to the shipment status. 3- When the part arrived it was O.E.M. as promissed and 170.00 dollars cheaper (no kidding) than the Toyota dealership. 4- The part actually plugged right in as promissed!!! I think I found somebody that I will conduct business with again, I am not a big fan of internet purchases because of bad return policies etc. But if they get it right the first time like these guys who needs a return policy? I give them two thumbs up!! 38849

As always, e-trailer products were delivered super fast, customer service was top notch and the product itself was great quality - even better than factory part with the addition of the standard 4-way connector - so why the poor rating???? Upon eager anticipation of the install, I find my factory 3 way connector piece has a male end, while the replacement connector also has a male end - this won't work. I would suggest you remove your factory connector to double check so you don't fall victim to this as I did. I was looking to replace a 2004 4Runner Sport Edition. 41283

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. 44353

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. 125369

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! 37435

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.

If your Tundra has the factory 7-Way connector then this would work. It would be worth the time to check the fuse blocks and see if any of the towing fuses are blown. Also, check the connections on the harness and make sure they are clean and clear. If fuses are blown or connectors are dirty or corroded, a new harness may not help.

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. 98439

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.

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. 63995

The product was exactly what I needed. The only problem I had was bolting the mount back onto the frame of my truck. The hole spacing in the mount did not match the original spacing by about .25" so I had to drill the mounting holes larger to match my bolt holes. 53660
