Draw-TiteTow Ready 20136 4-Flat to 5-Flat Connector Assembly, Black

Have had it on my boat trailer for a year now. I googled how to connect it as I have never installed one. Was easy. Popped off my back brake light ( Tacoma 2004), used the connectors supplied and was essentially done. Secured it to the frame. I ended up purchasing a 5 PIN cover for it so it doesn't get dirt inside during off times. Not one single issue. Great quality.

Worked out well although the main wire was short, may have been with my vehicle due to having my lights on my hatch of vehicle though

Just what I needed to adapt my boat trailer's 5 pin to vehicle's 4 pin wiring harness. I spliced the 5th blue wire into our toyota highlander's reverse light (this is the wire that when energized disables the trailers surge brakes). I used a butt connector instead of the included line splicer though. This is a good kit and it worked great for me. I hang the blue wire out the back hatch when in use.

I needed a conversion pigtail for my Jeep to my boat trailer to make the lighting work, this product mated well with both the Jeep and the trailer wiring harness's . Could not locate same item in local stores and pricing was much lower + free shipping with my prime account. Gott Love it!!!!

Just what I needed any easy to install. I did not use the wire splicer since I do not trust them, but rest of kit was perfect.

As stated in other review this does exist and works perfectly for converting from a flat 4 to a 5. Just splice into backup light wire and your done.

Works perfect.

Rewired my trailer connector.
