Video Transcript for Curt Wiring - Trailer Connectors - C58155 Review

Speaker 1: Today we're taking a look at the Curt 7-Way RV-Style Trailer Connector for the vehicle end. This 7 pole RV-Style trailer connector hardwires to your vehicle. It accepts the 7-Way plug on your trailer to power your trailers signal lights. It's constructed of a durable molded plastic construction so it's going to resist rust and corrosion. It has a spring loaded lid with an internal gasket that's designed to keep out dirt and moisture.Mounting bracket is not included. If you're in need of one you can check out some great options at etrailer.com.

The mount holes on this unit up and down. They're separated on center by an 1 1/2 and then side to side they're separated on center by 2 1/2 inches. Now, when you're ready to install the unit you'll need to take this back piece off. The reason why I like this connector is because it's a twist off application. A lot of the older style plugs use a screw to hold that in place.

You just grab it, twist it, and it pops right off giving you really easy access to the connection terminals.Then you would place your wiring through this portion here, feed it out this end and then make sure that you connect all of your individual wires to the correct terminals. Each terminal is labeled for its function so that allows for easy connecting. Once you have it all connected, place this piece back on, twist it to secure it in place, and on the bottom side here there's a set screw that'll need to be tightened. That closes this portion around your wiring to create a really nice, tight seal. That's gonna do it for today's look at the Curt 7-Way RV-Style Trailer Connector for the vehicle end..

We accidentally backed into a ramp and busted our original Curt connector that came with our wiring harness. It however did not come with a diagram, and the annotations in the plastic housing were incorrect for our vehicle.



by:

Excellent product. Swapping out leads from old OEM Ford 7 pin to this was as simple as comparing the Ford lead function to the Aluma trailer lead function and making the swap. Made the connection to the trailer w/o cutting any wires! Re-drilled my Ford bracket and attached the connector w/o issue...except my locating the holes...had a bit of elongation on the bracket holes to properly align.

This is my third order which speaks for itself. Best Customer Support, order handling, shipping expediency, packaging , price and product quality. Lori B took my order over the phone. She was very courteous, knowledgeable and strongly represents the Companies Customer
Service Policy. Looking forward to Order #4...Wentzville, Mo., (The Show Me State) and they sure showed me.

Perfect for my application. Mounted an Ammo box on the tongue of my stock trailer and brought all wires up through the bottom of box and connected them to the female plug inside the box. Made a 3 pigtail to connect from trailer to the truck. When finished towing I roll up the pigtail and put it in the Ammo box. This protects the pigtail from the elements and cows chewing on the pigtail.

These are amazing...product and customer service are amazing. I would highly recommend a 5/8 hitch pin lock tho...we love etrailer

  • Parts Needed to Install 7-Way in Bed of 2019 GMC Sierra for Fifth Wheel/Gooseneck
    Your 2019 GMC Sierra 2500HD will have the 7-way trailer wiring behind the bumper but it may not have a wiring harness ran to install a second 7-way in the bed of the truck for fifth wheel/gooseneck wiring. So what you'd need for that is the # 41157 which plugs inline with the 7-way at the rear of the truck and gives you a harness and connector you can install in the bed of your truck. I attached an install video for this for you to check out as well.

  • Recommended 7-Way To Hopkins Molded Trailer Wire with Different Colors
    The Curt 7-Way RV-Style Trailer Connector - Vehicle End # C58155 will connect to the Hopkins 7-Way RV Style Connector with Molded Cable # H20046 to make an extension with the following pin to color combinations because Hopkins uses odd colors. White to Ground Rede to Left Turn and Brake Brown to Right Turn and Brake Green to Tail Lights/Running Lights Blue to Trailer Brakes Black to 12V power Yellow to Aux/Reverse I've attached a photo to give you the locations to the pin functions so...

  • Troubleshooting Trailer 7-Way Connection Between 2004 Chevy 1500 and 2015 Ford F-150
    The Ford Replacement OEM Tow Package Wiring Harness, 7-Way # 118242 is the correct harness for certain Ford F-150 models from 1997 to 2004. It uses factory specific plugs and then connects to a US Car connector at the 7-way and that portion is universal yet the t-connector is not. It sounds like you have a trailer that works on one and not the other and the issue with that situation is normally a ground issue on the trailer itself. Check the main ground near the coupler or battery...

  • Would 7-Way Trailer Wiring Circuit Have Amperage Rating for Powering 13 amp Horn
    Standard trailer wiring circuits on 7-ways like the part # C58155 and # PK12706 are rated for up to 40 amps so if you wanted to use a 7-way like this to power a horn that is rated for 13 amps you certainly could.

  • Recommended Trailer 7-Way Wire Size
    The Curt 7-Way RV-Style Trailer Connector - Vehicle End # C58155 doesn't have a specified maximum wire gauge. We choose to use 10 gauge wire # 10-1-1 when hardwiring in most cases. We do directly hardwire that 12v 10 gauge wire without any step down connector. Most manufacturers use 12 and 14 gauge wires for different functions on pre-wired assemblies.

  • Availability Of a Trailer Battery To Tail Light Flasher When Trailer Is Disconnected
    While there is not a single item that will do what you are looking for you can build one quite easily. First you will need a 7-Way # C58155 which will allow you to connect directly to the trailer 7-way. Then you will need either the Custer Single Function LED Strobe Driver # STR-QRLY if your trailer has LED tail lights with up to 420 milliamps of draw, or you will need to source a flasher from a local auto parts store if you have incandescent tail lights. From there wiring is straight forward...

  • 7 Way Trailer Plug Will Not Stay Seated In the Vehicle 7 Way
    This can be caused by a few things, but as you have enough slack in the wire, it is most likely just one of two things. The door flap, for the lack of a better way to put it, on the 7 Way plug on the towing vehicle snaps down on a tab on the 7 Way plug coming from the trailer. These can break off which causes them to come uncoupled. If this is the case, the 7 Way trailer end will need to be replaced with something like the Optronics # A7WCB. But it could also just not be seated all the...

  • Solution for Older 7-Way Plug Not Fitting Curt 7-Way
    It's probably best to replace the 7-way socket with a new one since the tester 7-way you have tried does. So for that I'd go with a standard plug like the part # A7WCB. This will plug right into your Curt connector # C58155.

  • Trailer Hitch Receiver and Replacment 7-Way Connector For a 2022 Chevy Suburban 2500
    The Draw-Tite Trailer Hitch Receiver # DT45515 is specifically designed to fit the 2500(3/4 ton) version of your 2002 Chevrolet Suburban without the EPA canister mounted on passenger side frame rail. The Curt 7-Way RV-Style Trailer Connector # C58155 will replace the factory 7-way that came on your Suburban. It is compatible with the receiver you are looking at and will bolt the the welded bracket on the receiver . The 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket # HM40975...

  • Can Curt 7-Way # C58155 Fit as Replacement for PK11916
    Both the Curt 7-way part # C58155 and the Pollak # PK11916 use the same round 7-way wiring connector and would fit your 2005 Chevy Silverado. The advantage to the Pollak for your truck is the twist lock style of fit that allows it to fit right into the bumper mounting location on your truck for a cleaner install. The Curt would fit but would require drilling the bracket # C67UR to the bottom of your lower bumper. From a wiring and connector standpoint the two are identical.

  • Replacement Trailer Hitch Receiver for 2011 Toyota Tacoma 4x4
    Yes, our etrailer Trailer Hitch Receiver # e98850 is perfect for your 2011 Toyota Tacoma as it fits all Trim levels. I feel that our hitch having the Matte Black Finish also looks better than the other Gloss Black hitches. While you're replacing the hitch you will want to replace the Curt 7-Way RV-Style Trailer Connector - Vehicle End Item # C58155. This will ensure that any worn or damaged terminals within the connector are replaced and you don't have connection issues with your trailer....

  • Recommended Wiring To Tap Into Truck 7-Way For Power and Lighting To a Camper Shell
    If your truck already has a 7-way which uses the Curt Universal Wiring Harness Connector # C56229 for the 7-way, you will be able to use the Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring Harness # 41157. This contains a 10' harness which will tee into your current wiring. You can mount the other 7-way in you bed and use the 7-Way Round RV Style Trailer Connector # A7WCB to run the wiring for your camper shell. Otherwise you will be able to splice the end of the harness to hardwire...

  • Where Do You Connect the Blue Brake Controll Wire If The Blue Wire Is Used For ABS on 7-Pin?
    Since you are going to be wiring for a 7-Way Blade # C58155 style connector you are going to run a separate blue wire from the Brake Controller # HA100400C to this connector. The 7-Pin # R7CB connector you have on your 2011 International 8600 Transtar is designed to be used on trailers which have air brakes and uses the wiring differently. I have linked a image with the different functions shown for the different connectors and you can see they have some of the same functions but may are...

  • Replacing a 6-Pin Vehicle Side Connector With a 7-Way Blade Connector
    I have included images below of the 6-Pin # PK11609 and the 7-Blade # C58155 connectors that you will be wiring. I do recommend using the positions rather than trying to go off the wiring colors as the colors can vary. You can use a Test Light # PTW2993 to verify the wires are in the correct places on your current 6-pin connector.

  • Solution for Replacing 6-Way Square Connector for Trailer that Needs Battery Charged
    All of the wires of the 6-way square part # 37995 are 18 gauge so this would not be ideal for use with a trailer that needs a battery charge circuit. I'd recommend switching the trailer and tow vehicle to a 7-way that you could use with a heavier gauge wire. On the trailer side the easiest way to pull that off is with the part # 277-000141. Then on the tow vehicle side you'd want a 7-way like the # C58155 and you'd be set. If you need any 10 gauge wire we also have the part # 10-1-1 which...

  • 7-Way Male to Female Extension Cord That is Expandable
    While our typical 7-way extensions like the Curt Universal 5th Wheel/Gooseneck 7-Way Extension # C56080 are a straight cable you can make an extension with a coiled cable. We have the Bargman 7-Way, RV-Style Connector w/ 6' Long Coiled Cable # WG54006-043 or 12' Long Coiled Cable # WG54006-046 that you can wire to a Curt 7-Way RV-Style Trailer Connector # C58155. The coiled cable will help protect the cord from dragging but gives you the expandability of its length. I have included a wiring...

  • Is There an Adapter To Go From 5-Pin Flat on 2017 Toyota Highlander to 7-Pin Blade on Boat Trailer?
    It sounds like you are trying to go from a 5-pin flat connector on your 2017 Toyota Highlander to a 7-way connector on your Ranger boat trailer. This type of connector is not made since the 7-way wan only designed to be used on trailer that require either a charge line or electric actuated trailer brakes. If your boat trailer does not require either of these the simplest thing would be to change the trailer to a 5-Way Flat # HM47910. Otherwise you could create an adapter using the same...

  • How To Keep The Towed Vehicles Battery Charged When Pulled By RV
    The best way to keep the battery on your towed vehicle (2020 Ford Escape) charged when flat towing is to use Roadmaster Battery Charge Line Kit for Motorhomes # RM-156-75 and Roadmaster Battery Charge Line Kit for Towed Vehicles # RM-156-25. The charge line # RM-156-75 connects to your RV's starting battery since this battery is connected to the alternator and will not drain down. Then you will connect the other end of the charge line to the pin in the 1 O'clock position on your RV's...
