4 and 5-Flat Trailer Connector Mounting Box - RP74641

Average Customer Rating:  4.3 out of 5 stars   (3 Customer Reviews)

- RP74641

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. 882858

  • 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.

  • 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.

  • Options for Mounting Dealer Installed Trailer Connector on 2008 Subaru Outback
    The Trailer Connector Mounting Box, part # RP74641 has slits at the corners of the hole in the back of the box. These slits can be enlarged by using a utility knife, and allow your trailer connector to pass through from the rear. To mount a connector I like the 4 Pole Knock-Out Adapter, part # 30601 with brackets # RM-910030-5 and # C57202. The # C57202 bracket would attach to your hitch using the included pipe clamp, bracket # 118137 would attach to it, and the Knock-Out Adapter would...

  • 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.

  • 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.

  • 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.

  • 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.

  • What Mounting Bracket For Wiring Harness Will Fit A Curt Hitch On A 2011 Kia Sorento

I also have the Hopkins Mag-Flat (TM) 4-Pole Mounting Magnet, # 38095, that is a magnet that will attach Also, the Tow Ready Mounting Bracket 4-Pole Flat, # 18144, is a 4-Way connector holder that will attach to the hitch or the bumper.

  • Mounting Bracket Options For 4-Way Trailer Connectors
    We do offer a couple of mounting boxes for 4-way flat connectors, but the style differs from the Draw-Tite Bracket, part # 18156. You can check out part # RP74641 and part # HM48755. 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.

  • 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.

  • Mounting Options for 4-Pole Connector on 2010 Mazda CX-9
    I have just returned from the warehouse and have looked at the actual hitch. The hitch does feature the mounting plate and is exactly as shown in the photo. The easiest method would be to keep the connector in the cargo area until needed. When you are towing, you can run the wire out the rear door and close the door on it. The weatherstripping around the rear door is thick enough that the wires will not be damaged, as long as you avoid the area around the latch. This method provides...

  • Adding a 5-Way Trailer Connector to a 2016 Jeep Cherokee
    If your 2016 Jeep Cherokee did not come with the factory tow package then the first step is to add a 4-Way flat connector using # 118605. I have linked a video showing an example installation for you. You can then turn it into a 5-Way by adding 4- to 5-Way adapter # 20036. Please note that a 4-Way flat can plug into a 5-Way receptacle so you won't have to have 2 different connectors on the Jeep. With the adapter you will need to find a place to tap into the reverse light wire. Jeep...

  • Trailer Connector Mounting Box for 4-Way Flat Trailer Connector
    It looks like the bracket used in the video you referenced is the Draw-Tite 6 and 7-Way Trailer Connector Mounting Box, 2-1/2 Inches # 18156. This bracket fits a 2-1/2 inch square tube hitch and is designed to mount a 6- or 7-way round trailer connector. If you are using a 4-way flat connector and would like an enclosed mounting box, we have the Reese 4 and 5-Flat Trailer Connector Mounting Box # RP74641 and the Hopkins Mounting Box for 4-way Flat Trailer Connector # HM48755. These connector...

  • 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. ...

  • Mounting 4-Pole Connector from T-1 Connector Part # 118269 on 2011 Hyundai Veracruz
    The 4-pole connector at the end of your trailer wiring harness can certainly be zip tied, but using an installation bracket like part # 18144 along with a no drill mount like part # 18140 is recommended for a clean looking installation. A storage box, part # RP74641 is also offered. On my wifes KIA Sedona, I used the no drill mount, part # 18140, the bracket, part # RM-910030-5 and the knock out adapter, part # 30601. Your existing 4-pole would plug into the rear of the adapter and would...

  • What Do I Need to Use Hitch 24733 with my 2004 Chevy Cavalier
    The hitch, # 24733, includes all the mounting hardware you need to install the hitch to your 2004 Chevy Cavalier. In order to tow a trailer, you also need to purchase a drawbar, and the ball itself that sits on the drawbar. The drawbar for this hitch is part # 3592 and the manufacturer says to only use this drawbar and only in the rise position. This bar includes a hitch pin and clip. Your drawbar requires a ball with a shank diameter of 3/4 inch. I have added a page link that will...

  • 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...

  • 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...

  • 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.

  • 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...

  • 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...

  • Trailer Wiring Mounting Box for a 2004 Jeep Grand Cherokee and Curt Trailer Hitch 13051
    If your 2004 Jeep Grand Cherokee has a 4-way flat trailer connector then for a mounting brackets there are a few options. You could start with # 18144 to hold the 4-Way and then attach it to either short bracket # 18140 or long bracket # 18136 which attaches to the hitch. For an actual box you could use # RP74641. If you need to mount a 7-Way I recommend bracket # PK12711U again with short bracket # 18140 or long bracket # C57202. For more of a box we have # 18159. If you need to...

  • 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.

  • 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.

    Your 2007 Toyota Avalon will need to be hardwired for a 4-pole trailer connection.

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...
