I need to rewire my trailer. Could you recommend a wiring kit with plug that matches the one I bought for my trailer? I have a 5×10 trailer.

If you have a 4-way trailer connector like # 118418 then I recommend using a wishbone harness to wire your trailer. The 20 Ft 4-Way Trailer Wiring Harness - Wishbone Style - 30" Ground # A20WB is my recommendation for your wiring because it will allow you to run 2 wired to each side. You will run the brown and yellow to the driver's side, and the other brown and green wire to the passenger side. The white wire will get connected to the trailer frame as a ground. The brown wires on each side will be used for parking/clearance lights. The green will be used for right turn and stop. The yellow will be used for left turn and stop.

If you don't already have lights on your trailer, I recommend using the Peterson Light Kit for Trailers under 80" Wide - 20' Wire Harness - Driver and Passenger # M540 which will come with everything you need for that size trailer. I've attached a couple of videos to help and have also attached a trailer wiring article with diagrams to assist.
