I purchased the Hopkins wire harness 48265 based on positive reviews. This is going on a vintage camper trailer that we rebuilt the back end. The back sheet metal that the tail lights mount to was replaced with new sheetmetal. Old wiring was routed to back and new sheet metal was installed, then lights were wired. I wanted to use a sheet of silicon seal on tail lights and that causes a grounding issue. So now ground wires will have to be run to frame. Since back sheet metal has to come back off, decided it was time to replace the wire system. Since it is hard to get at the wiring for the tail lights, it was important for me that I use a quality harness. This harness had the 18 gauge wire with 16 gauge for ground. Some harnesses were 20 gauge wire and reviews for those was described as cheap and concerns that it wouldn't last but a few years. Everything I read about the Hopkins 48265 was positive. If the wire set is as good as the quick attention I received fron Etrailer, I m sure it will be 5 star. Thanks to the people at Etrailer. Kev

  • Trailer Taillights Not Illuminating With Hopkins Wiring Harness On 2016 Dodge Grand Caravan
    In most cases when only one function is not working properly or intermittently it means there is a bad ground connection somewhere on your setup. I would double check the ground connection on the vehicle Hopkins plug part # HM11141995 to make sure it is grounded to a clean bare metal surface free of debris or paint. Grounding issues tend to show up most with the running light circuit because those lights remain on continuously and so they draw more current. You also want to make sure the...

  • Recommended Replacement 4-Flat Wiring Harness
    From the image you attached, I think what you have is each of the taillight circuits on your 4-way have two wires ran to them for each side of the trailers wiring. You can wire the two wires of each pin to the single wires of a new 4-way allowing the circuits to get the same signal. Depending on how much of the wiring length needs replaced, you can use the Hopkins Endurance Easy-Pull Harness w/ 4-Pole Flat Connector, # HM38134 for a short length. If you have damage to the last few feet...

  • Do I Need To Run Separate Wires To Each Tail Light For the Running Lights On a Trailer?
    You can route the wiring in either orientation. A harness like the Hopkins Endurance 4-Way Flat Trailer Wiring Harness # HM48265 is referred to as a wishbone harness and comes with 2 separate brown wires that are bonded to the corresponding green and yellow wires for running down both the left and right sides of the trailer. This is best when you have a trailer like a boat trailer where it is harder to protect the wire running across the rear of the trailer.

  • Length of White Wire on Hopkins Endurance 4-Way Harness # HM48265
    I went out to our warehouse and measured a length of 34-1/2 inches for the white ground wire from where it comes out of the back of the 4-Way on the Hopkins Harness # HM48265. The white wire is 16 gauge. I have attached a short video review that you can check out as well.

  • How to Install Ground Wire To Trailer Connector on Utility Trailer
    Grounding through the ball doesn't work well, as you've found. If the current harness doesn't have a ground circuit, the wiring must be fairly old as it's pretty typical for a trailer connector to have a ground circuit. The fact that you're blowing fuses leads me to believe you might also have a short circuit in one or both your turn signal/brake lamp circuits. You'll want to replace the existing wiring harness on the trailer. This is pretty simple to do, and will only take an hour or...

  • Recommended Trailer 4-Way Wiring Harness For a 6' X 12' Utility Trailer
    I recommend the Hopkins Endurance 4-Way Flat Trailer Wiring Harness # HM48265. This harness uses a wishbone design so that you will have conductors for your running lights and tail lights that run down each side of your utility trailer. Since your Side Marker Trailer Lights # MC35AEB, Peterson Tail Lights # 432400 and Peterson Identification Light Bar # 428100 are designed to ground on the frame this harness also uses a frame mounted ground. The entire harness is 30' long ensuring you will...

  • Recommended Wiring and Lights for Utility Trailer
    I'm assuming you want to replace everything here so I will start off with a 4-way. I recommend using the Hopkins Endurance 4-Way Flat Trailer Wiring Harness - 30' Long # HM48265. This will give you a lot of wire to work with so you can hook up all of your lights. This uses your typical 18 gauge wire for the lights and 16 gauge for the ground. If you need additional wire you can use the # SWC97FR or # DW02923-1. You could use the Self-Stripping Connector with Waterproof Sealant - 14-18...

  • What Wire Gauge Is Used With Hopkins Endurance 4-Way Flat Trailer Wiring Harness
    The wires included with the Hopkins Endurance 4-Way Flat Trailer Wiring Harness, part # HM48265 are all 18-gauge. Most 4-way wiring harnesses will be a 16 or 18 gauge wire. The lower the number, the bigger the wire, so the 18 is bigger than the 20-gauge you asked about.

  • Trailer Wiring Harness Compatible with Peterson 435800 Trailer Stop/Turn/Taillight
    We don't offer a plug and play trailer harness that would plug directly into the Peterson # 435800 trailer taillight. The lamp includes a 3 pin pigtail that would plug into the rear of the lamp which would wire directly into the trailer wiring. If you need a 4 pole harness for your trailer, we offer them in varying lengths. • For a 20 foot harness, use part # A20WB • For a 25 foot harness, use # A25W2GWB • For a 30 foot harness, use # HM48265 • For a 35 foot harness, use # A35W42B To...
