I can certainly help you find all of the parts needed to rewire your dump trailer and we do have a lighting kit that will work for you. However we do not have any kind of plug-and-play rewiring kit.

The taillight kit I recommend for you is the Optronics Waterproof, Over 80 Inch LED Trailer Light Kit with 25 Foot Wiring Harness # TLL16RK. This kit includes 2 red LED taillights with the functions needed for trailers over 80 inches wide. The included wiring harness has 25 feet of wire to connect your taillights to the front of the trailer. If you use a 7-Way trailer connector, the 4-Pole flat connector can be cut off to wire the lights to the 7-way connector.

You will also need front clearance lights if your trailer's GVWR is more than 10,000 pounds and front side marker lights and reflectors, both of which are fulfilled with # MC32AB. If your trailer has fenders, you will want front and rear clearance lights there as well, # MC65RB and MC65AB.

If you need a new trailer-side wiring connector, I recommend the Epicord 7-Way Molded Trailer Plug with Junction Box # 277-000141. This connector comes pre-wired to a junction box. Using a junction box will make it easier to make multiple connections and to replace wires when the need arises. I've attached a review video of a similar junction box for you.

To run the ground and signal wires for the trailer's brake assemblies, I recommend using the duplex wire # 12-2-1, sold by the foot.

To make the wiring connections for the lights, you will want to use 16-14 gauge butt connectors like # DW05744-10. To connect the wiring to the brake assemblies you will want to use 12-10 gauge connectors # DW05745-10. To make the connections at the junction box, you will want to use ring terminals, # 44-5310A for 12-10 gauge wire and # DW05702-1 for 16-14 gauge wire.

I have attached a help article on trailer lighting requirements for you.
