Nilight 7 Way Trailer Junction Box Color Coded Studs for Rewiring Projects

Incredibly useful for organizing trailer wiring and ensuring each wire stays in the correct place. The build quality is excellent—sturdy and reliable—which gives me full confidence that these will hold up over time. What I really appreciate is how easy they make it to keep everything neat and traceable. Troubleshooting is a breeze thanks to the accessible contact points that allow quick and accurate testing. A must-have for anyone working with trailer wiring.

Overall, great product for the price. Made it easy to install the 7-way pigtail. As a retired industrial maintenance electronics technician. I can fully appreciate the product. Been looking for a similar product for quite a while. I used various diameters of heat shrink to to bundle the wires. Heat shrink goes inside the product. There is plenty of room for wire placement. For my particular installation, I had to lengthen the wires from the trailer end. Set that up first and made sure to use the colors in this product. Tested with a IPA Light Ranger MUTT before final installation and checked out OK. The only cons: No locking nut(s) for the studs and the plastic wire clamps cannot take a lot of torque when tightening the screws. Otherwise, I'll recommend this product to anyone who has a similar setup. Used on a 6'x12' tandem axle dump trailer.

Apparently, a child on a bike ran into the plastic electrical junction box on my trailer. I did not see it happen, so it is somewhat of a mystery to me. You can see the removed and broken junction box and terrible wiring job with twist-on connectors. I could not find a suitable exact replacement that fit the existing holes in the frame. However, the Nilight was mountable in the existing area using the one existing hole and screw from the old junction box. Notice that rewiring uses crimp-on circular connectors that fit onto aluminum posts in the Nilight box and that these connectors were crimped onto every wire, secured on the posts with a nut and wiped down with dielectric grease. One remaining issue was exactly how to mount the NEW bolts on either side of the Nilight box. I drilled 7/32" holes in the frame, then used self-tapping 1/4"-20 aluminum bolts from Grainger to secure the box. The trick is to use a low drill speed and medium-high torque on your drill. What I like most about the Nilight box is that it is essentially waterproof now to a level where it could be used in a marine environment, and the connections won't get wet. It is a more durable box and great value for the price.

I will have to silicone around the wiring because the plastic plugs aren't waterproof and mine didn't have rubber plugs. Nice product, looks great and keeps wiring connected. I used my own stainless steel bolts to install.

Worked great & easy to install.

I borrowed a friends trailer - and it had electrical issues. It seems that someone tried to drive off before unplugging it and it made a mess out of the wires. I purchased this junction box and a new pigtail and was able to get the trailer fixed properly. It sure made a nice/easy job out of a real mess. This is definitely better than crimp splices, or spade splices or any other type of wiring 'fix' that I could find at the auto parts store.

works great

Easy to install ..makes job look more expensive and professional

لأن خامته كانت متوافقة مع الوصف

Good works for what I wanted it for

Love these boxes. I have now bought 3 of them for trailers I have built. And I would buy another. So easy to wire up.

Muy practica ya que se pueden hacer las uniones sin problemas
