This was exactly what I was looking for. I am re-wiring my landscape trailer from the flat 4 prong plug to this round 7 prong. Now I have no need for a adapter. And with this long set up I will have one less splice. I have been searching for a item like this one. But all the places I went nobody sold them: Rural King, TSC, Napa, or even a Triple Crown dealer. Thank you Etrailer for-such a wide selection of products to amazing price. 713434

5 stars for the quality of this product, The electrical is well wrapped and the plastic is a good quality. I have yet to install the wiring harness in my 2000 17ft Casita Spirit Deluxe. Whoever owned the trailer before nearly caused it to burn down with all the splicing of the original wires into the 2 converter boxes with 8 electrical outlets in this tiny trailer. They dragged the original harness on 2 separate occasions. I looked all over for a longer one, e-trailer had it at a reasonable price. I feel confident that I will have good results. Thank you! 662845

This is a great product. Very good quality & now after a year of use on my livestock trailer its still like new. One thing I really liked was that it has a sealed head so the usual problems with corrosion are eliminated. 599282

Very nicely built cable. BUT-- Be aware of color coding on connections. When used with Junction Box 38656, the colors do not match at all. This made for a few hours of unnecessary troubleshooting. 219744

I haven't installed the parts yet but the bargman connector looks better made than the one that came on my newer trailer. The junction box 38656 is going to work great on my older trailer, making it easier to rewire it with a bargman connector 50-67-008. 175590

  • Replacement 7-Way Trailer Connector to Rewire an 18 Foot Gooseneck Trailer
    The 22 foot long Bargman molded 7-way trailer conector, part # 50-67-008, is probably enough for your trailer. It depnds on how much, if any, of the existing wire you want to keep and connect to the new harness. If you need to make it longer you can use part # DW04914-1, which is sold by the foot. The wire colors on the 7-way and the extra wire are the same.

  • When Installing a 7-Way on a Trailer is a Junction Box Required
    You don't have to install a junction box when you install the # 50-67-008 on your trailer. If you wanted you could just run the wires to each function as needed. The black wire of this connector would be the one to use for the charge wire of your battery. Using a junction box like the part # 38656 would make installing the wiring easier though. I attached an install video for it for you to check out.

  • What Wire Gauges does Bargman 7-Way Molded Trailer End Connector and Cabel Use

  • Wire Color and Functions of Bargman 7-Pole, RV-Style Connector # 50-67-008
    The key here is that the functions are in the correct locations. Wire color is going to vary from manufacturer to manufacturer which is why you should always wire by function and use a circuit tester like # 3808 when wiring in a connector like # 50-67-008. The reason we list the wire color and functions on the product page is because there is no official industry standard for wire color. If you tried to wire by matching colors, there is a very good chance that it will be wired incorrectly....

  • Instructions to Wire a Trailer for Electric Brakes
    It sounds like you are speaking of the wires for the brake magnets. If this is correct, you will need to connect one of the wires to the brake controller output wire on your trailer connector and the other wire will need to be grounded to a clean metal surface on the trailer. I have included a diagram for you.

  • How to Determine Trailer Wiring Functions on a Travel Trailer for 7-Way Replacement
    Trailer wiring color codes can vary greatly so I have a solution for you, but I can't tell you which color wire goes where on your trailer for wiring up a new 7-way. However, you may look around the wiring junction box or pin box of your trailer. There may be a diagram there. Instead you will want to use a jumper wire from a 12 volt source like a vehicle battery to apply voltage to all of the wires of your trailer wiring to see what activates. It can help to use masking tape to label...

  • Troubleshooting a Hallmark Trailer That Lost Trailer Wiring Power After Replacing the 7-Way
    First thing I would do is test the 7-way at the rear of your 2009 Ford F150 for proper function with a circuit tester like our part # PTW2993. This will determine if the problem is on the truck or the trailer. Check out the video I attached to see how this is done. If the voltage isn't where its supposed to be on your truck connector then most likely there are some trailer wiring fuses or relays that might be blown on your truck. You will want to inspect them and replace as necessary. If...

  • Which Wire is the Reverse Wire on the 7-Way Molded Trailer End Connector

  • What is the Function of the Black Wire on the Bargman 7-Pole Trailer Connector # 50-67-008
    The black wire on the Bargman 7-Pole Trailer Connector, # 50-67-008, will carry 12 volt power from the tow vehicle for accessories on the trailer that require a 12 volt power source such as an additional trailer battery, breakaway battery or any other accessory. This wire will carry 12 volt power from the tow vehicles battery. You can attach it where you would like, or tie it off if you do not have a use for that function. I have listed the functions of the wires below. Yellow: center...

  • Compatibility of Aluminum Wire With Copper Trailer Wiring
    You do not want to mix aluminum with copper like found in the trailer connectors like # 50-67-008 as well as the trailer lights and brake magnets. The dissimilar metals will cause galvanic corrosion and can cause wire failure. I recommend instead using # 12-1-1 and # 16-1-1 sold by the foot for your wiring needs.

  • Troubleshooting Trailer 12V Charging Circuit That Does Not Re-Charge Batteries Fully
    The 12V auxiliary power feed on your truck's 7-way can deliver a maintenance charge to the trailer's on-board batteries, but it does not carry enough juice to re-charge a battery that is depleted. A depleted battery really needs to be re-charged by a shore-power charger like one of the CTEK units, such as their # CTEK56353. I own one of their chargers (for about 6 years now) and it works well in my always-on 24/7/365 duty cycle on my motorcycle and lawn mower batteries. Another possibility...

  • How Much Slack Is Needed In Trailer Wire Connection To The Tow Vehicle?
    The length of wire desired depends on your vehicle connection and your personal preference. You want enough slack for turning, but not so much for dragging as you mentioned. A little extra slack isn't a problem and not enough could lead to stress and wire connection problems. In general, you will want between 16 inches and 24 inches of wire beyond the tongue depending on where your connection point is on your tow vehicle.

  • Troubleshooting Running Lights and Brakes Not Working Correctly on a Haulmark Trailer
    The problem with the running lights not working could be several things. The first thing I would check is to make sure the 7-Way on your 2006 Chevy Silverado is getting a signal for the running lights. Using a circuit tester like # 40376, test the running light circuit which should be the pin in the 11 oclock position if looking at the face of the plug. If the signal is coming through, make sure that the corresponding pin on the trailer side (pin in the 1 oclock position if looking...

  • Horse Trailer Electric Brakes Lock Up When Backing Up the Trailer
    There could be a short in the truck or trailer side connector that occurs when the vehicle is put in reverse. The center pin is typically the reverse light circuit. You will want to make sure that the truck and trailer side connectors are clean and free of corrosion inside and out. Inspect the power wires to the magnets and look for pinched, frayed, or damaged wires and fix as needed. Make sure the ground wires are attached to clean and corrosion free bare metal surfaces.

  • Installation of Backup/Observation Camera on Van and/or Travel Trailer
    If you are looking for a backup camera installation on an Aspen travel trailer, the backup camera can be wired one of two ways. You can connect the camera power wire to the reverse light signal if you only want the camera for backing up. Alternatively if you want the camera to serve as an observation camera as well as a backup camera you can connect the camera power wire to the running light circuit. This will give you that constant power instead of only when your vehicle is shifted...

  • Gauge Wire to Use for Trailer with Triple Axle Setup that is 43 Feet Long Overall
    It does sound like you need heavier gauge wire for the brake output circuit on your trailer to activate them properly. For that many axles and that length of trailer 10 gauge for the circuit just isn't going to cut it. I'd go with 8 gauge wire like Dexter recommends.

  • Blade Style and Round Pin Style Trailer Side 7-Way Connectors
    The Bargman 7-Pole, RV-Style Connector, # 50-67-008, is a blade style connector. If you see the term RV style that is usually and indicator that it is a blade style. If you need a 7-Way round pin connector you can use # PK11702. You would need to attach the wires yourself by taking apart the connector to access the location inside where the wires attach.

  • How To Remove Tail Light Lens on 2009 Box Trailer
    Normally to remove a light lens there would be screws to remove to remove the lens. If you do not see screws then the lens may be a snap on. To remove a snap on lens you could use a flat head screw driver to pry the the lens off carefully. Since I am not sure of your exact tail light assembly it is hard to say exactly how to remove the lens or if the lens is removable at all. Some tail lights are sealed to be submersible.

  • Adding a New 7-Way Trailer Connector and Wiring to a Car Hauler Trailer
    You will likely need some additional wire to reach the lights when installing 7-Way connector # HM20087. If you just want 4-wire you can use # DW04923-1, sold by the foot, or # 16-4B-1, also sold by the foot. You will also need some butt connectors such as heat shrink version # DW05744-5. If you want all 7-wires you can use # DW04914-1 which is sold by the foot as well. Another option is a 7-Way that is considerably longer, # 50-67-008, which at 22 feet long is more than twice the length...

  • Installing 7-Way Wiring Connector to Trailer For Reverse Light Function
    The center pin on your 7-way on the trailer side is the reverse light function. These can be different colors, which I get is confusing, but you will need to do some deductive reasoning or use a circuit tester to determine the function and color. For instance the yellow wire on the Hopkins # H20044 or the Bargman # 50-67-008 is the reverse wire which isn't the norm because the yellow wire is typically the left turn and left brake wire. I've attached a photo and an article to assist. You...

  • Which Trailer Wiring Connector Has a Pin for Reverse Lights
    In order to add reverse lights to a trailer would would need to have a 7-Way on the trailer, like # 50-67-008, and a 7-Way on the vehicle. On the vehicle side, if you are looking at the back of the 7-Way where the wires connect, the reverse light circuit is the center pin. It will need to connect to a reverse light wire behind one of the vehicle tail lights. On the trailer side the matching pin is again the center pin. So from that pin, you would route wire to reverse lights. Reverse...

    The 5th function for 40 ft. Wishbone 5-Way Trailer Harness with 30" Ground and 5 ft. Blue Wire Item # A40W5B is meant to go into an electric reverse lockout on a trailer with surge brakes. On the vehicle side the 5th function ties into the reverse lights so that when the vehicle is in reverse the lockout solenoid will be energized and not allow brake fluid to actuate the brakes.
