Video Transcript for Hopkins Wiring - Trailer Connectors - HMC20031 Review

Today we're going to review part number HMC20031. This is the Hopkins Quick Fix 4-way flat trailer end connector. Now this is used if you happen to have a damaged 4-wire flat on your trailer and you need to replace it, or if you just have some pigtail wires and you want to put a 4-way plug on the end, you can use this part for that. Basically what you would end up doing there when you just put your wires right in here. Lay the bare part of the wire right into the connector, and then take your cover plate, once all the wires are in. Just go ahead and put this in, and then push it all the way down and it will actually lock into place. It protects your connections, so there's no external splices. Basically just to give you an idea, I have a sample here.

You can see: here's your normal four wires you'll see on a 4-way flat. You've got your white, brown, yellow, and green. Basically on your trailer, if you have a damaged connector, you cut it off. You have these wires, or if you just have the wires and you need a 4-way, basically what you would do .. and what also helps you out is on this 4-way, it's actually marked.

It says "RT" for right turn. "LT" for left turn. "TM" for the tail lights, and then "GD" for ground. Basically it shows you where the wires. Now normally on a 4-way, you have this normal color combination here, but what I would recommend to do is actually probably put power to each circuit to make sure and verify. Just don't always go by the colors.

It's always good to test the circuit to make sure it lights up the correct circuit you're going to install in here. Basically all you'd end up doing is taking you're . Like, in this case, it says right turn . Your white is the ground. Brown is the tail lights. Your yellow is your left brake and turn signal.

And your green is your right turn and brake signal. You'll see the end one says right turn, so we take our right turn, which is the green. You just lay the wire in there and then you take the exposed portion and you actually push it down and it will actually clip in there and hold into place really tight. Then once you get all four put in there, again, you just put this on there, push it into place and you'll be ready to go. But that should do it for the review on part number HMC20031. This is the Hopkins Quick Fix 4-way flat trailer end connector. .

This is the first time I've used this particular product manufacturer. In the past I used a similar trailer end from Reese. Installation was easy other than ensuring that all four wires were properly aligned with the forked terminals. I used a hammer to lightly tap the cover in place, and ensured the "clips" on the ends of the cover were securely in place. Time will tell if the "clips" will stay secured. Reese uses two small screws to keep the cover in place. Thanks eTrailer! 102116



- HMC20031
by:

Only one of four wires penetrated the copper wiring thru the sleeve when the cover was installed. Sure, you can remove the cover & wiring and cut a slit where the wires were intended to pierce, but, that defeats the whole purpose of just slipping the wire into each corresponding section and having the cover push down the wires to get pierced. 253079

Product was exactly what was needed. Much better than dealing with multiple wire nuts. If you can replace an extension cord plug, why not a trailer plug? Why are these things not in the big box stores? Was surprised the product was as hard to find as it was (google searching). 410331

  • Replacement 4-Pole Trailer Connector for Utility Trailer with 5-Wire Wishbone Wiring Setup
  • When a 4-pole (4-pin) flat trailer connector actually has 5 wires this simply means it is a 'wishbone' style connector with dual running light wires. These dual wires just make it easier to connect to the running lights on both sides of the trailer. Examples of such items are # A35W42B, # A20WB and # A10-4225VP. If your trailer wiring is still okay and you just need a new 4-pole plug to re-connect the leads from the trailer you can use Hopkins Endurance Quick-Fix Replacement 4-Way Flat...

  • Converting a Trailer with a 6 Square Connector to a 4-Way Flat Trailer Connector
  • If the trailer is a Jayco trailer, you will just need Adapter # 30104, to go from the 4-Way flat on the 2006 Honda Odyssey to the 6 square on the trailer. If the trailer is a different brand, this adapter will not work. Instead, you will need to convert one of the connectors to be compatible with the other. If you convert the trailer, the other 2 functions on it will be lost unless you converted it back again. If you converted the vehicle, it will only be compatible with trailers that...

  • Different Ways to Wire a Lighted Headache Rack
  • I have two options for you to install a headache rack with lights such as the B&W Custom Headache Rack part # BWPUCP7500BA on your 2008 Ford F-250. However, both of them will require splicing as they do not make an in-line connector specifically for this application. If you wanted to make the headrack removable in regards to the lighting functions then you would need to install a 4-way like part # HMC20031 on the end of the wiring harness that goes to the headrack and then splice a...

  • Yes, there are some trailer side 4-Ways that have short leads or no leads that you could use. We have the Hopkins model # HM48110 that is 12 inches long. Another 12 inch long model is # 18004. And then we have Quick Fix connector # HMC20031 with no wires. I have included a link to these and other options for you.

  • Replacing 4-Way Connector on Trailer with 8 Wires
  • For just the needed 4-Way by itself I recommend the Hopkins Quick Fix # HMC20031 that features a removable cap that makes it easier to insert the wiring from your trailer. From the looks of the picture you attached you probably have three ground wires (white) and three running light wires (brown), the remaining green wire being for right side turn/brake and the yellow for left side turn/brake. With that being said I highly recommend still testing them each for function for verification...

  • Replacement 4-Way Connector For Wishbone Trailers
  • Your utility trailer has a wishbone wiring harness therefore, in order to replace the connector you will need the Quick Fix (TM) 4 Pole Flat Trailer End part # HMC20031. There is an extra running light wire on the wishbone harness that runs down each side of the trailer eliminating the need for a jumper wire. The Quick-Fix connector is designed to replace your existing 4-way without the need to hardwire or splice any wires. To install, you will need to sever the wires just before your...

  • After Replacing Trailer Side 4-Way Wishbone Harness with Non-Wishbone, Running Lights Don't Work
  • The issue is likely in how the 2 brown wires are connected and then connected to the single brown from the new 4-Way. You basically need to make the 2 running light wires into one and then butt connect to the single brown. You could use the Quick Fix, # HMC20031, twist the two running light wires together and then put the newly combined wire in place. Or you could go ahead and swap the 4-Way for a wishbone, # A20WB. There also could have been a short that fried the lights when the...

  • Converting 5-Wire Separate Wiring on Motorcycle Trailer to Combined 4-Wire Setup
  • The easiest way to convert your Time Out trailer to standard combined 4-Way setup is to use the Curt 2-to-3 Converter # C56196. You will first just need to cut off the existing 5-Way connector on the trailer. Then on the output side of the converter the green wire will connect to the green wire on the trailer. The yellow wire on the converter will go to the yellow wire on the trailer and the red wire will go to the red/blue wire on the trailer. The brown running lights wire won't go...

  • How To Change Wrong 4-Way Connector On A Trailer From Vehicle End Connector To Trailer End Connector
  • I would recommend to use the Draw-Tite T-One Wiring Harness, # 118379, on your 1992 Toyota Pickup. This will give you the correct harness for your vehicle with a 4-pole flat connector at the rear of your vehicle. This harness will plug in behind the drivers side taillights and passenger side taillights. On your trailer you can remove the 4-pole flat vehicle end connector that is on there now and attach the Hopkins Quick Fix(TM) 4 Pole Flat Trailer End, # HMC20031. This will give you...

  • Installing Connector on Trailer with Electric Brakes and Battery Wire
  • A 4-Way flat trailer connector like # HMC20031 does not have a pin/circuit for the 12V battery wire. A 4-Way like this will only work to connect with another 4-Way on the tow vehicle so that the trailer's basic signal lights (brake light, turn signals, running lights) are powered. If your trailer is equipped with electric brakes and you need the 12V wire to maintain the charge on a battery (or power a 12V accessory) then you will need to have a 7-Way connector on both the tow vehicle...

  • How to Wire the GloLight LED Trailer Tail Light Part # STL178RB to a Trailer Connector
  • The white wire on the back of the GloLight LED Trailer Tail Light part # STL178RB is for the ground. If you were wiring it to a trailer connector like part # HMC20031 then you would just need to make sure that it is attached to the ground terminal and no additional grounds would be needed. The outer ring of the light that you are referring to is made of plastic just like the body of the light is. The wire leads are around 6" long. I have attached a review video for you.

  • Replacing 4-Way Plug on Trailer Wishbone Harness with 5 Wires
  • You can indeed connect a standard 4-Way plug like the Hopkins # HMC20031 to the 5-wire wishbone harness on your boat trailer. A wishbone harness uses a separate running lights wire for each side of the trailer (instead of having to run a jumper wire across at the rear). To connect the wiring to the new 4-Way you will just need to connect the 2 running lights wires together (which should both be brown but you will want to test them to be sure) using a butt-connector like # 05731-5.

  • Recommended Wishbone 4-Way Trailer Wiring Harness with 14 Gauge Wire
  • I do have an option for you but none of our trailer wiring harnesses we offer come with that heavy duty of a wire. The only 4-way wishbone kit we offer 40' long is the 4-Way Wishbone Trailer Wiring Harness part # A40W42B which has 20 gauge wire. I am not sure why you would need that heavy duty of a wire for tail lights but you can make your own harness using the Jacketed 6-Wire part # DW04906-1 (per foot) and the Quick Fix 4 Pole Flat Trailer End part # HMC20031.

  • Alpena Trailblaze Tailgate LED Light Bar Does Not Show Passenger Side Lights
  • For starters, I recommend that you check the ground for the 4-way trailer connector on your vehicle as this could very well be causing your issue. If the ground checks out then this leads me to believe there is an issue with the trailer connector on your 2004 Chevrolet Silverado or the trailer connector on the Alpena Trailblaze Tailgate LED Lights part # ALP77229. I see you said that you replaced the 4-way but I didn't catch if it was the 4-way on the vehicle or the 4-way on the light...

  • Can the Quick Fix(TM) 4 Pole Flat Trailer End be Used with Wishbone Trailer Wiring
  • A wishbone wiring harness is simply two wires coming out of the running light circuit, one for each side of the trailer, so you do not have to run a jumper wire from one side to the other. If you have wishbone wiring you can still use # HMC20031. You would splice one a few inches back from the trailer connector into the other tail light wire and then attach the single wire to the Quick Fix 4-Way. The other option is to use a wishbone trailer side 4-Way, # A20WB, and cut of the wire to...

  • Troubleshooting 4-pole Wiring on Haulmaster Trailer
  • Since you've tested the 4-pole harness on your 2012 Chevrolet Sonic and found it to have the correct lighting signals you can start your trailer troubleshooting at the main ground wire that connects to the trailer frame. This white wire's ring terminal needs to make solid contact to a clean bare metal spot on the frame, one that is free of paint, primer, rust and grease. Since none of your trailer light circuits work it is likely that the ground or a bad connector is the cause. You can...

  • Replacing Damaged 4-Way Connector on Trailer with 8 Wires
  • Standard trailer wiring usually features a wire for right turn/stop, a wire for left turn/stop, a wire for the running lights, and a wire for ground. Your trailer likely has separate wires for each function along with a couple of ground wires. In order to replace your broken 4-Way with a new one like the Hopkins # HMC20031 you will want to first test the wires on the trailer by applying 12V power to them (or trace them to where they lead to) to determine their function. Then it is just...

  • If your trailer has a 4-Round that looks similar to # PK11402, you can clip off the plug and connect the wires to a 4-Flat that will fit the 4-Way on the 1999 Lincoln Navigator. You can use the Quick Fix(TM) 4 Pole Flat Trailer End, # HMC20031, or directly wire a trailer-side 4-pole connector like # 18004. The shielded pin is the ground and is usually a white wire. The pin next to that is for the tail and running lights and is usually a brown wire. The next pin is for left turn and is...

If that is the case then this part is not available separately but you can obtain something similar with the Pollak Wiring Harness Extension part # PK11-934 and the Quick Fix 4 Pole Flat Trailer End part # HMC20031. If you need butt connectors to finish up your connections you can use part # DW05745-5.

  • No Running Lights After Installing Aero Pro Trailer Light Kit TL36RK
  • If the running lights have worked on other trailers then we can narrow down the issue to your trailer and not the tow vehicle. The first thing you will want to do is test the brown wire directly behind the trailer plug. If there is no power then you have a connection issue between these two plugs. That said, you can easily wire a new plug on with part # HMC20031. If you do have power here then you will need to begin tracing this brown wire back while testing it with a volt meter to see...
