    • Replacement plug for Tundra
Product works as described. Replaced the one I installed years ago and was a simple process. Overall, good quality and easy to install

    • Quick and easy!
Quick and easy install! Saved myself a ton of time and work by purchasing this. Fit perfectly and quality was on point.
Reviewed in the United States on July 1, 2024 by Very cheaply built. The bars for the roof bent imediately when trying to install roof fabric. Instructions are in chinese only so pictures will have to do. For the price it should of have a little genie pop out of the box and put it together too.
    • Holding Up Well
I needed a 7 pin socket with an option of still using 4 pin. Instructions were clean and the quality of the design and materials seems great.

    • Great for the Value.
Ok, it's not as good as a major brand model, however for the value it's fulfilling my needs, especially for how long these things last under use. Pros. Currently well priced. The wires come pre-connected for a 4way, and the 4way bracket is separate if you have to modify your mount. The bracket is good quality with all hardware included. The wire guage is of good size. The wires are well protected from weather. Cons. The wire colors are not standard to match major brands, so make sure to keep your hookups straight as you go. The quality of the plastic as not high, so the receiving hole is tight. You have to push hard to get the 7 barrel plug to seat so the flap can hook and hold. It will get easier with use. But you need two hands so you don't bend the bracket as you force the trailer plug into the seat.. The flap spring is a bit weak but it will hold the plug from coming out. The wires are shorter than the major brand's, so depending on your situation, when cutting off your old one, leave some wire as leads. Overall, for what you get, and for the life expectancy of add on trailer wiring, it's a good buy. After you mount it put a wadd of grease on the hardware to keep the rust at bay as it is just standard metal. ... show more

    • PROMASTER 2500, AKA Winnebago Roam
My RV came with a flat four pin connector in the rear and I needed to be able to tow a trailer with brakes. The Promaster is NOT wired for a brake controller and if you use a standard controller by the driver you are going to have to pull a lot of plastic up to get to the wiring. BETTER way. Buy this. It connects to your already existing four pin connector. You run a hot to your coach battery and a cold to the frame of the vehicle. You seal off the other wires on this because you do not need them. (Do NOT cut them as you might someday need them in the future.) Then install a CURT 51180 brake controller at this connector. You down load an app on your phone and use your phone to run the brakes as needed. No need to do anything inside the vehicle. ... show more

    • Exactly what I needed
Review Image by Gunther Gunther
The original trailer connector on my truck was corroded very badly and needed replaced. This item was perfect for me because not only does it replace the damaged part, but it also gives you a 4-flat connector beside the 7 pin round. You never have to worry about picking up a trailer somewhere and rummaging through the glove box for your 7-to-4 adapter. Since my truck already had the wires for the 7-pin, I chopped the 4 pin connector off the back and connected it straight to the existing truck harness to get rid of some length and connectors. ... show more
