Video Transcript for Draw-Tite Wiring - Trailer Connectors - 18004 Review

Today, we're going to review part number 18004. This is the Draw Tite 4-Pole Trailer End Connector. This is 12 inches long. It also comes with the 4 wire caps to attach it to the wires on your trailer. Basically, the standard 4-way wires would be the white for the ground, the brown for the tail lights, the yellow for the left turn and brake, and the green for the right turn and brake, so when you go to attach this to your trailer, you do want to test the wires using a tester to make sure you connect the wires function to function, because sometimes the colors will not always match up. A good thing to do is to use a tester that we sell separately on our website that you can use to test the wires and then hook these wires using the included wire caps. That should do it for the review on part number 18004, the Draw-Tite4-Pole Trailer End Connector. .

The wiring harness worked great. I used it to connect a back up camera..Instead of fooling around with getting to the back up wires on the tail lights, I just clipped the harness to the wires on the back up camera(one live, one ground) and plugged that into my 4 pole trailer plug in the back of my pickup. when I turn on my headlights. it turns on the camera. It took all of 3 minutes to do that vs God no how long trying to disassemble and reassemble the tail lights to find a backup wire. 526617

Comments

The parts are still on my European trailer and working well! The trailer is a German brand and started its life there in Germany being pulled by my American-spec Jeep Wrangler. The trailer’s wiring and the Jeep’s connections needed to be massaged in order to work. The parts I ordered from etrailer and the writeups for the project on your site made it all possible. Now the trailer is titled and registered in Virginia and enjoying its life on this side of the Pacific!

received the item in 4 business days, just in time to fix my trailer for commercial lawn service. Never used wire caps before, they are great. My 4 pole trailer harness actually has 5 wires, to my surprise, and I was able to fit both brown (running lights) in the cap and it works fine. I did wrap it all up with electrical tape to be safe. 193099

The video on installing the trailer hitch was very helpful to me. I was fooled by the Trailer End Connector. I assumed it was the wire connector that I needed to attach to my car, and there was no wiring instruction. So I struck out there. Fortunately I had someone who knew what they were doing help me to wire the proper connector to my car. Your service overall was fast and I did appreciate all the help we received from you.

  • Trailer Error Message with Hitch Light on a 2018 Ford Escape
  • I do not believe that there is an issue with your 2018 Ford Escape or there is an issue with the Oval LED Brake Light Trailer Hitch Receiver Cover part # CR-017. Unfortunately, the electrical systems in newers cars today are very complex and they do not like when aftermarket accessories are used. The issue you are having is that the vehicle thinks there is a trailer attached when you have the hitch light plugged in. The power draw from the hitch light is not comparable to that of a trailer...

  • Trailer Wiring Recommendation for Kia Soul and How to Make Adapter to Tow Trailer w Separate Wiring
  • Basically, you will have to make an adapter. You will need 3 important parts. First you will need a vehicle to vehicle converter # 118158. Next, a trailer side 4-Way, # 18004. And finally a vehicle side 5-Way, # 20016. It will be assembled like in the picture I have provided using butt connectors like # 05731-5. If the trailer has incandescent bulbs then this harness is limited to 1 brake/running light (dual filament bulb) and 1 turn signal bulb per trailer side. For trailer...

  • Troubleshooting No Turn Signals on Trailer Towed by 2015 Nissan Frontier
  • If the factory 4-pole trailer wiring on your 2015 Nissan Frontier is not providing turn signals the issue could have several causes. It is possible the factory/dealership did not install the required relays in the Frontier. We offer the relays by themselves as part # C57000 and as part of a complete wiring harness kit # 118525. You could also have a blown fuse in the power distribution box; this you can check by taking off the lid and finding the fuses related to trailer lights. Check...

  • Trailer Wiring Recommendation for a 2015 Kia Soul Towing a Motorycle Trailer
  • For your 2015 Kia Soul you would want the part # C56222 if your vehicle does not have LED taillights or part # C56220 if you do have LEDs. Now to connect to the wiring on your trailer you will first need to make an adapter. There are two good ways to accomplish this. You can convert the motorcycle trailer and the motorcycle to a combined system that uses the same light for the brake light and turn signals. The rear lamp assemblies would need to be replaced, and put a converter like...

  • Troubleshooting No Trailer Turn or Brake Lights After Extensive Testing
  • I'm incredibly impressed with the extent of the testing you've already performed and thus can understand your frustration at still not finding the root of why your turn/brake signals are not working on the trailer. Reading through your troubleshooting steps a couple of things come to mind. First, it sounds like you have tested for continuity with the trailer wiring but I couldn't tell if you used the ohm reader to actually determine the voltage you're getting, especially as you get further...

  • How to Keep CR-017 Brake Light Hitch Cover From Blinking w/ Turn Signals
  • There IS a way to get the # CR-017 to operate only with the running lamp and brake light without blinking with the turn signals, you'd need a 4-pole trailer end connector, part # 18004, a vehicle end connector, part # 18002 and a vehicle to vehicle taillight converter, part # 118158. You'd wire it together as shown in the provided photo. You'd essentially be making a large adapter that would isolate out the brake signal.

  • Wiring of a European Trailer That Uses a 13-Pin Connector on a Ford F-150 with 4 and 7 Way Connector
  • Unfortunately, we do not carry the European style connector you are trying to locate. On a European 7-Way trailer connector, the connector is pinned out differently than those used in the United States. They also use more wires to cover the same functions as a U.S. wiring configuration. So it would be much more beneficial to wire the trailer to work with a U.S. configuration rather than to convert and adapt the existing trailer wiring. You will need a vehicle to vehicle tail light...

  • Running Lights Will Not Work on a Big Tex Gooseneck Trailer
  • The first thing we need to figure out is if the problem exists on the truck or trailer. To do this you will need a circuit tester such as # ALL640595 or a meter if you have one. Disconnect the trailer from the truck and have someone sit in the truck to operate the running lights while you test the connector at the back of the truck. The running light circuit should be the pin in the 1 o'clock position on a vehicle side 7-Way connector. If there is power on that pin then the issue is...

  • Troubleshooting Trailer Wiring Where Only Left Hazard Light Works
  • First thing you should do at this point is test the 4-way of the wiring harness with a circuit tester part # PTW2993 for voltage on all of the right pins when the taillight signals are being applied. Just like in the video I attached. If the voltage checks out there but the trailer lights still don't function right then the problem is on the trailer wiring. That would mean that problem is either due to a ground issue or a short issue. Make sure that the trailer side connector is clean...

  • 50mm Ball and Getting Lights to Work on Altera Strada DL3 Bike Rack on 2016 Chrysler Town & Country
  • We do have 50mm hitch ball # EH53C-C so all you will need now is a ball mount that fits the 2 inch receiver on your 2016 Chrysler Town & Country. Since the trailer hitches are close to the ground on vans I recommend a ball mount with some rise in it such as Draw-Tite ball mount # 40346. The electrical is a little more complicated but the good news is that you don't have to have lights on a bike rack in the US. But if you want them to function then an adapter will need to be made since...

  • Replacing a 6-Way Trailer Connector on a Rockwood XL 1280 Pop Up Trailer
  • It sounds to me like the previous owner did not wire his home made trailer connector properly. If the trailer came with a 6-way connector, then that means there are two additional wires coming from the 6-way connector for the trailer brakes and, most likely, an auxiliary power source. If you are not worried about supplying power to the trailer brakes or auxiliary power source, then I would first recommend checking your local laws to see if brakes are required on your trailer. Some states...

  • Trailer Wiring Recommendation for a 2015 Jeep Compass
  • The 4-way connector that comes with the Tow Ready Wiring Harness part # 118539 that you referenced is the standard vehicle side 4-way. It sounds like someone wired up your trailer with the wrong 4-way. So your best option would be to replace it with a # 18004.

  • Wiring US 4-Pole Trailer Connector to For Trailer with European 7-way
  • I am not aware of the existence of an adapter, but one could be easily constructed. You will need to find a vehicle-side socket to receive the plug from your trailer. We do not carry them, so you will need to obtain one locally. You will also need a vehicle to vehicle taillight converter like part # 118158 and a trailer side 4-pole like part # 18004. You would then wire the converter as shown in the diagram I provided. Using this adapter will separate the turn signal back out so that...

  • 7-Way to 5-Way Adapter for a Honda Pilot with 7-Way and Trailer with 5 Pin Connector
  • A 5-pin round connector is pretty rare, are you sure you do not have a 6-pin, 5 pins in a circle with one pin in the center? Having both trailers work with your 7-way connector on the Pilot will be pretty easy. You will need a 4 pole to 7-way adapter, part # PK12716. This will allow you to tow the trailer with the 4 pole connector with no problem. For your trailer with the 5 pin round connector, you will have to make a wiring modification to the trailer because of the separate brake...

  • Troubleshooting 4-Pole Trailer Connector-Turn Signals and Brake Lights not Working
  • What's the year, make and model of your vehicle? A vehicle can have one of two different taillight set-ups, a combined or a separate system. On a combined system, both the brake lamp and turn signal are carried on one circuit, just like the wiring on most trailers. This is a very simple wiring system, that allows you to simply wire in a connector like the # 18004 connector you mentioned. On a separate system, the turn signal and brake lamp are on separate circuits. Take a look at...

  • How Do I Install a Trailer Light Harness on a 2004 Jeep Grand Cherokee

  • Draw-Tite Does not require the use of a stabilization strap with non-trailer loads such as a bike rack or cargo carrier on their hitches like part # 75742. It might be a good idea to use one though if you are loading a bike rack or cargo carrier close to the tongue weight capacity of the hitch, vehicle or bike rack/cargo carrier, whichever is rated lowest Curt requires the use of a stabilization strap, # 18050, for any non-trailer loads such as a bike rack or cargo carrier.

  • As long as the trailer hitch on your Four Winds motorhome has a 500 lb tongue weight capacity, you will be able to haul your Yamaha WR250R motorcycle. I recommend looking at the Ultra-Fab Motorcycle Carrier, # UF48-979033. This carrier only weighs approximately 50 lbs, has a weight capacity of 500 lbs, and is approved for use behind motorhomes. The total tongue weight of this carrier plus your bike would be approximately 350 lbs on your trailer hitch. Additional tail lights are...

  • Troubleshooting Left Turn/Brake Lights Not Working on Trailer But Testing for Power at Socket
  • If you are testing the left brake/turn signal lights on the trailer right at the socket of the assembly itself and getting power, but the lights themselves don't work when the bulbs are in place then my first thought is a weak ground connection on the assembly. Since you would be grounding the circuit tester as well, this basically could be strengthening the ground enough for that circuit so that you get power when testing but not when the bulbs is back in place. Trailer lights will...

  • 4 Pole Trailer Connector with Two Wires Connected to One Pin
  • As for the white ground wire that you mention, this wire should be firmly attached to a clean metal surface on the trailer. As the lights are currently working properly, you are most likely picking up the ground connection through the trailer ball. This is a pretty unreliable connection, and can lead to intermittent light malfunctions or failures. Regarding the current connector on the trailer with the two wires running into one pin, some smaller trailers are wired this way. Instead...

  • Trailer and Tow Vehicle Brake Lights Not Working when 7-Pin Trailer is Connected to 4-Pin Vehicle
  • On both a 7-Way and 4-Way trailer connector the brake lights and turn signals are on the same circuit so it is strange that the brake lights aren't working. But, brake lights draw more constant power than the running lights or the turn signals so it could be a situation where the trailer lights are causing to much power draw. The first thing I recommend doing is using an adapter to connect the 7-Way on the trailer to the 4-Way on the tow vehicle. You can use # 37185. You will plug the...

If your RV has a 4-way flat connector, then you can install a 4-way trailer end connector like part # 18004. If your RV has a 7-way connector, then you could install a 7-way to 4-way wiring kit like part # RM-164-7. This allows you to install a 4-way socket on your Jeep and includes a Flexo-Coil cord to connect...

  • Looking for Adapter For 6 Pole Square Trailer Connector on Dutchman Camper
  • It probably wouldn't work. Jayco used a proprietary harness that most likely wouldn't fit. The 6 pole square harness is pretty much obsolete at this point, your best bet would be to cut it off and replace it with a more common trailer connector. In the photo, it looks like there's only 4 wires on the wiring harness. If that's the case, you could just use # 18004. If the wiring harness has 6 or 7 wires, I'd recommend using a 7-way connector like part # A7WCB, as it's what's most commonly...
