This multi-function, vehicle-end connector converts any 4-way flat, vehicle-end plug to a combination 7-way outlet and 4-pole flat outlet.
I used this on my 2017 RAV4. This harness provides me the flexibility of using flat-4 or a 7 way connector for towing flexibility. The RAV4 is a small tow vehicle and I like the added security of electric brakes even on lighter single axle trailers which the 7 way allows. I plugged this adapter into the flat-4 connector provided by the "T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector Item # 118578" and used heat shrink tubing around the crimp connectors for the brake controller wires to keep moisture out.
This would be a 5 star rating if all my trailer plugs fit equally well. The preformed trailer wiring plugs are a perfect fit, (4 out of my 6 trailers have them), but two aftermarket plugs are a struggle to get the retention notch to fit inside cover hook that keeps the plug in place. ((Otherwise the plug pops out)). Bottom line is I would buy this connector again because of the price point and ease of installation. From now on I will be buying the preformed trailer wiring harness for the perfect fit.
Needed to slightly modify the bracket clearance holes to have the plastic holes line up properly and fit cleanly. Not a big deal but someone else may have struggled with that if they expected a simple install.
Installed on my 2011 F150, part worked great as advertised on install. The 4flat adapter was easy and obviously ground too. However, the Ford truck has the wiring harness for the rear components sitting about 12”-16” away from where you would realistically want the 7 way mount to sit. I’m sure many other vehicles are this far away as well. Therefore to get to the remaining 3 wires I had to add in another roughly 8” of wire to each introducing some extra connectors and more areas for failure. Not too big of a deal but I would say for this parts blue, black, and yellow cord you should make them another foot longer that way they seamlessly work on any vehicle and the buyer just has to zip tie the excess out of the way on installation. Wouldn’t cost y’all much but would save time and effort for the customer. Otherwise great part, easy install, and good install videos as well
I love this setup. I used it on another vehicle, and recently installed it on my 2021 Toyota Highlander Limited. I need the RV connections for my camper, but like having the 4-lead connection available for the occasional Haul.
This was a little bit of work to get set up (considering I was also adding the 4 way flat as well, as the truck didn't have any trailer wiring, maybe not that bad) Worked out very well
Makes for a professional installation. I just needed to add a small piece of metal to attach the bracket to where I wanted the final install.
Good looking piece, quality material.
Ray - 09/02/2021Instructions have you tearing apart the cargo part of your 2021 Sienna (I have an AWD model) when the connector is easily accessible under the spare tire! Installation was easy once I found this out from another review!
Nice piece! Made my own mounting bracket to move inward so it wouldn’t stick out to far!
really fast shipping was as stated . installed in less than 20 min. very happy would recommend them for any of your hitch needs.
Needs heat shrink connector's so they are water tight seeing they are under truck
this product was exactly what I needed and I could not obtain from a local supplier. Price was right. It arrived within a reasonable time frame, install directions were clear and the initial install was simple and I had connectivity right away. I was able today to test with the trailer attached and it all works. Thanks,
First plug in and the pin cones out, try to fix it and the whole thing just falls apart. Really disappointed in this plug setup. Nothing holds the pins in the plug except the rubber coating in the back. Which doesn't work all that well because all the wires in the back side are wet after the first rain drive.
GREAT PRODUCT, GREAT PRICE, FAST SHIPPING, EXACTLY AS ADVERTIZED, FIT PERFECTLY, QUALITY ALL THE WAY AROUND! I LOVE IT!!!
This product worked great for me. I had a little trouble fitting it to my Toyota Sienna (it would have helped if the 4 pin flat connector could be located on either side of the 7 pin round connector), but functionally I’ve had no issues. One weakness I could see is the included butt connectors are not heat shrink type so they’re not weatherproof. This could lead to corrosion in the wiring eventually. Otherwise good product!
Bought for a 1998 GMC K2500 pickup. Needed wiring hookups for both my 4 wire ten foot trailer and also my 16 foot trailer with round hookup. Fit my wiring perfectly, had it installed in 30 minutes. Had it for a year now and have had no problems, still working great. The videos and instructions from etrailer are great, makes the job very simple.
Prompt shipping and delivery. Good install info included.
Used this connector adapter on a previous vehicle and will now install it on my current one. Easy to install and performed as required. Instructions were easy to follow, too.
Works great.
Looks great and was delivered on time
Shipped quicker than expected, fit was tight but right.
Has worked without fail!
Super easy to install! Works perfectly!
uniquely above most online ordering, customer support I've experienced.
