Video Transcript for Review of Reese - Wiring - RP74641

Today, we'll be taking a quick look at the four and five flat trailer connector mounting box. This is going to have a little protective cover go over your four and flat pole on your vehicle end. And it basically just provides a little like house for your wiring to keep it nice and protected. It comes with two self tapping screws and a couple of zip ties and you're wiring to stores inside there helps to keep any excess wiring safe and tucked up out of the way, not only out of the elements, but also you don't have to worry about it dragging on the ground and getting damaged that way. We've got a length of four pole wire with the four pole end. So you can see how it just slips into that little slot at the bottom.So whenever you have your wiring mounted up, can put that through there, fold it up inside and then snap the door closed.

And then the two flanges on either side allow you to mount that up again, either with those self-tapping screws or the zip ties. I like that they include the zip ties with it, that way you don't have to make any modifications to your bumper or your hitch. It makes an easy mounting point, if you change your mind, you can always clip those off and use some other ones. As far as the dimensions, the widest point, which will be the ends of those flanges. It's about five inches wide, the box itself it's about four or three and four, three and three quarters inches wide.It's about two and a quarter inch tall and right around one and three quarters, inch wide or deep.

The distance center to center of those mounting holes is about four and a half inches. Doesn't come with this length of four-pole wiring I just wanted to have something to show you how those wires would fit in there. Even if you have a five pole wiring, there's still enough space, there's enough of a gap there that should be able to get it tucked in side and keep that wiring protected.The one thing that I would say with this case is that over time I think you might have an issue with that door maybe getting worn and snapping off potentially. Disconnected now, but if it we're to snap off, it'll still pop into place it just might not stay connected whenever you open it up so that's one thing to keep in mind. Pretty lightweight It's just a universal black color all the way around.

It's made of a Thermo plastic construction. So not going rust anything out causing any damage there just keeps our wiring up and out of the way. That's going to do it for our look at the four and five flat trailer connector mounting box..

Customer Reviews

4 and 5-Flat Trailer Connector Mounting Box - RP74641

Average Customer Rating:  4.3 out of 5 stars   (18 Customer Reviews)


It very cheaply made and I have to get down on my knees to get the wiring back into the box. If I don’t get everything just right it falls out of the box. I know, one gets what they pay for.


The connector box looks great and was easy to install. I didn't have anywhere I could use the sheet metal screws because I didn't want to drill into the hitch itself. So I opted to use the 2 zip ties that were included.


Just what I needed. Easy to install. Great company to do business with.


Works to keep some water and dirt off of the trailer connector. Decent room for the connector and a few inches of the wiring. Closing is just putting plastic tabs into plastic slots so I am curious to see how long that lasts. But still good a year later. The location where I put it made it tight to get the hitch pin in and out, so was not the best for my application. But not the Box's fault.


etrailer is great! I could not find this trailer plug housing anywhere else.


works as expected


No computerized voices at Etrailer! You actually talk to the staff that are very helpful with all your concerns. They are very courteous and professional. They are my go to company for any products I need.


Works and installed easily but a little flimsy. Still holding up after a year though.


Have not installed this. The quality is good




Exactly what my husband wanted. He put It on the car right away and it was perfect! Quick transaction.





Reasonable and works

  • 4-Way Mounting Bracket Recommendation for Larger 4-Ways
    The 4-way mounting bracket part # RP74641 can basically fit any 4-way harness as it can also fit the larger 5-ways as well. I attached a review video for you to check out as well.

  • Mounting a 4 and 5-Flat Trailer Connector Mounting Box
    The 4 and 5-Flat Trailer Connector Mounting Box # RP74641 will mount to either your hitch or the rear fascia of your vehicle with the self-tapping screws or zip ties provided. It is up to you exactly where and how you want to mount the box. The trailer connector wires will have to be fed through the back hole of the mounting box, so the connector is stored in the box. The wires will come out of the back of the box, and then into your vehicle for attachment.

  • Will a Sierra Brand 4-Way Flat Trailer Connector Fit Tow Ready Mounting Bracket
    Mounting bracket # 18144 fits most 4-Way flat trailer connectors. We don't have Sierra brand connectors so I can't test it. We do know that it will not work with Hopkins, Wesbar, TAP or Plug-N-Tow brand connectors. The worst case scenario would be that the connector is too large and you would have to file out the opening on the bracket a little. Or you could go with a different type of bracket such as # RP74641 which is a larger plastic box.

  • Running a T-One Vehicle Wiring Harness to the Outside of Jeep
    It is an easy process to install the wiring harness; I will quickly go over the steps, but also attach the instructions in a PDF file for your convenience. You are correct with assuming you use the taillights. Start on the driver's side, remove taillight, and plug harness in; next ground the harness with the white wire. Route the T-Connector end with the 4-flat down through the taillight pocket between bumper and body and towards the center of the bumper. Secure remainder of harness with...

  • Installation of Replacement OEM Tow Package Wiring Harness 118258 On a 2008 Hyundai Santa Fe
    I have attached an installation video of the # 118258 wiring harness on a 2009 Hyundai Santa Fe for you. The installation is pretty straight forward once you have gained access to the factory connectors. To do this, you are going to start by lowering the spare tire, and then you would open up the cargo area and remove the access panels, threshold trim, trunk floor panels and trays. Proceed by removing the trim panel on the driver side, but make sure you remove the fastener on the driver...

  • Recommended Mounting Bracket for a 4-Way Trailer Wiring Harness on a 2000 Toyota Sienna
    I went out to the warehouse and pulled the wiring harness, # 46475, and the mounting bracket, # 18144, to test them together. The two will not fit together without either modifying the bracket or the harness, so I do not recommend using them together. Instead, I recommend using a mounting box, part # RP74641. This box will provide a clean look while also help to keep the harness out of the elements. You will need to enlarge the hole in the back of the box so the end of the harness will...

  • What Brand of 4-Way Trailer Connectors Fits Tow Ready 4-Way Connector Mounting Bracket
    The 4-Pole mounting bracket # 18144 is designed for Tow Ready brand 4-Way trailer connectors but could also fit other brands such as Curt wiring harnesses. Some 4-Ways have an extra thick housing that is not compatible. This seems to be the case with Hopkins brand 4-Ways so I would not use this bracket for a Hopkins 4-Way. For l thicker than normal 4-Way connector I would use housing # RP74641. It will also help protect the 4-Way from the elements.

  • What Would Happen if Vehicle Tongue Weight Capacity Was Exceeded
    You'll most likely damage the vehicle frame before you do the hitch when you exceed the tongue weight capacity of a vehicle. The trailer hitch from Draw Tite part # 24763 that fits your 2012 Honda Civic has a tongue weight capacity of 200 lbs which you'd need to stay under that figure as well as the figure listed in your owners manual since you are only as strong as the weakest component in your towing setup.

  • Is There A Wiring Mounting Tab On the Hidden Hitch Like The OEM Hitch for My 2004 Lexus RX330
    There is no tab on the Draw-Tite, item # 75153, for mounting the wiring harness. We do carry mounting options for the wiring on your vehicle. For the 4-way trailer connector you can use the 4 and 5-Flat Trailer Connector Mounting Box, item # RP74641, which is one of our best selling mounting options for the 4-way flat connector. If you have a 7-way connector then you can use the 6 and 7-Way Trailer Connector Mounting Box for Round Tube Hitches, item # 18159, which works very well with...

  • Does the T-Connector Wiring Harness Violate the Warranty on 2010 Chevy Equinox
    The T-Connector Wiring Harness for the 2010 Chevy Equinox, part # 56094, is very easy to install. You will simply plug it into the factory connectors behind your tail lights and you will be ready to tow. Installing a wiring harness will not interfere with your warranty. I would recommend two things. If you will be towing frequently, I suggest a mounting bracket like the 4 and 5-flat Trailer Connector Mounting Box, part # RP74641, to keep your plug from dragging the ground. I also recommend...

  • Will the Connector Mounting Box Mount Directly to the Draw Tite Hitch # 75528 on a 2009 GMC Acadia
    I went out to the warehouse and tested the fit of the 4 and 5-Flat Trailer Connector Mounting Box, item # RP74641, with the Draw-Tite Max-Frame Class III Trailer Hitch Receiver, item # 75528, and it will not bolt up to the existing holes in the receivers electrical mounting bracket. The mounting holes in the Connector Mounting Box, item # RP74641, are 4-1/2 inches on center, and the receivers electrical mounting bracket mounting holes are 2-1/4 inches and 1-3/4 inches apart on center.

  • What Trailer Wiring Bracket is Recommended for the 4-Way to 5-Way Adapter TR20046
    The # 47515 would be a bit too thin to fit the # TR20046 perfectly so a better option would be the # RP74641 which is essentially a box that would hold the connector and protect it from the elements.

  • How and What I Need to Wire a 4-Pole Trailer Connector on a 2007 Toyota Avalon
    Your 2007 Toyota Avalon will need to be hardwired for a 4-pole trailer connection. I would recommend the Upgraded Circuit Protected Taillight Converter Hardwire Kit, item # 119178KIT, for ease of installation and protection of your vehicles sensitive electronics. You will need to match the color-code wires from the tail light converter too the appropriate vehicle wires. Use a circuit tester, included with the kit, to find the correct wires behind the vehicle taillights and splice the...

  • Wishbone 4-way Recommendation
    I think your best option for a 4-way would be to get a 20 ft. Wishbone 4-Way Trailer Wiring Harness # A20WB. This is a male side 4-way with a 20 feet section of wire that could easily be cut down to 2 feet. This is also a wishbone setup that has 2 wires run for the running light circuit.

  • Connector Protector for a 5-Pole Flat Wiring Harness
    The 4 and 5-Flat Trailer Connector Mounting Box, Part # RP74641, is a very good 5-flat protector. You could also use the 5-Way Flat Trailer Connector In-Line Circuit Tester, part # 20115, which has a protective cover on the end that is not connected to the vehicle.

  • Trailer Wiring Harness Mounting Bracket for a 2006 Dodge Magnum
    We have numerous brackets that you can use to hold/house the trailer wiring connector on your 2006 Dodge Magnum. A simple solution for a 4 or 5-Way trailer connector would be the Trailer Connector Mounting Box, # RP74641, which you can simply zip tie to the cross tubing of the hitch. For a 7-Way, you can use # PK12711U, attach it to # 18140 which then would attach to the hitch cross tubing with the included hose clamp.

  • How to Protect Trailer Wiring on a 2011 Subaru Forester from Winter Weather
    If the dealer does not have the exact part, you may be able to take the grommet with you to a hardware store where you may find something that will work in its place. I could not find an aftermarket grommet. It may be that the vehicle is still fairly new and that part is not yet available. Another option is to provide some protection for the wiring. For the actual wires, you can use a wire loom, # 39035. I would would go ahead and wrap the wiring in electrical tape for added protection. ...

  • Recommended Electric Boat Winch For 4000lb Fiberglass Boat
    The Dutton-Lainson StrongArm Electric Winch - Marine - 9,000 lbs # DL25215 would be plenty strong to pull your 4000lb fiberglass boat on your bunk trailer, and already includes a 2" x 20' polyester strap so you will not need to purchase one separately. Since the wiring included with the # DL25215 has a quick connect already on it you can run that to the battery on your truck and mount the quick connector near your 7-way like you mentioned. You will then use the Dutton-Lainson Electrical...

These are designed to protect your 4-way flat connector. I have attached links to our product pages that list the mounting brackets we have for 4-way round and 4-way flat trailer connectors.

  • How to Protect Bulldog Winch Quick Connectors for Winch Wiring on a Truck
    The Bulldog Winch quick connectors # BDW20047 themselves do not have any sort of cover to protect them from the elements. But what you could do is modify mounting box # RP74641 and that will help protect them. There is no one place that you have to mount the connectors. You can mount them in a place that works best for you. We do sell 10 gauge wire. I recommend # 10-2-1 since it is 2 wires in 1 sheath. It is sold by the foot so if you needed 20 feet you would put 20 in the quantity box.
