  • A must for 4 prong plugs
Color: 7Pin to 7Way 4Way Adapter
This item is a must if you are like me and have trailers with 4 prong plugs. I used to use those adapters but those are inconvenient especially if it falls off or someone steals it then you would be stuck without no light for the trailer. I would recommend this item for sure you still have your 7 prong plug with the addition of the mounted 4 prong plug. ... show more

  • Affordable 7 way plug
Color: 4Way to 7Way Adapter
Everything about this plug operated as expected without paying a premium for beauty. It is straightforward with all the items needed to upgrade my 4 way plug to a 7 way mounted below the bumper. Quality appears good. After 6 months is operating without issues.

  • Good idea
Color: 4Way to 7Way Adapter
I like how well it integrated to existing 4 pin system. Only complaint is crimps did not work well even when using a professional crimping tool. And yes I do electrical work for a living

  • Sturdy bracket, quality materials
Color: 4Way to 7Way Adapter
Converted my 4-way plug to a 7-way just by plugging this into existing harness. Clear directions for wiring in trailer brakes to this adapter.

  • BLUE WIRE IS ONLY 14AWG. GROUND ALSO 14AWG!
Color: 4Way to 7Way 4-Way Adapter Wiring
Nice product…… except the blue wire for the trailer brake is only 14AWG. Should be 12AWG disappointing. The ground is also 14AWG and should be 10AWG. This will cause issues if you trailer brakes and lights are drawing a fair amount of power is it need to ground to the truck…..all the components of a trailer share 1 common ground. Sad too because Nilights trailer junction box wiring is correct AWG all around. ... show more

  • Good product.
Color: 4Way to 7Way Adapter
Works well, easy to install, not as sturdy as an OEM plug but I was still satisfied with it, especially for the price.
