Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located in your rear cargo area, behind the driver's-side and passenger's-side rear access panels. You will have to remove the interior plastic covers to access these connection points. Once you've plugged in the T-connector, run the hot lead to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery.


Once installation is complete, the 4-way connector will be stowed in an out-of-the-way location within your cargo area.


It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.


Powered Tail Light Converter with Surface-Mount Technology

A tail light converter is built into this T-connector. This converter is a circuit-protected, battery-powered unit that bypasses the electrical routes that are used by a basic wiring harness. As a result, there is virtually no draw on your tail light circuits.


Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are compatible with the wiring system of the trailer. This converter combines the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.


Curt builds each tail light converter using surface-mount technology (SMT). This method of construction involves soldering electronic components directly to the surface of a printed circuit board. SMT eliminates the need for leads, which are used in older through-hole technology. The result is a circuit board that is smaller yet provides more routing area and that offers superior performance, reliability and durability.


Curt SMT Circuit Boards

Circuit boards constructed using SMT have been shown to perform better under rough conditions with excessive vibration than those made using the through-hole method. And where would vibration be more likely to occur than in towing applications? Curt converters also produce less heat, leading to increased durability and longer life. In addition, lower levels of resistance ensure better performance, especially for parts that operate at higher frequencies.


Each Curt circuit board is made using high-quality components that are pieced together in the most technologically savvy fashion, leading to greater predictability and reliability in functioning.

  • Parts Needed to Install 4-Way and 7-Way on 2015 Ram ProMaster 1500
    To install both a 4-way and a 7-way on your 2015 Ram ProMaster 1500 you would need to first start with a 4-way kit like the Curt # C58DR and then convert it to a 7-way with the part # 37185 which also has a 4-way on the side of it just like you are wanting.

  • Recommendation For Carrying 2 E-Bikes Behind a Class B RV on 2017 Ram ProMaster 2500 Chassis
    First of all if your Class B camper did not come from the factory with a receiver the Curt # C13207 is my recommendation as it is made in the USA. This will bolt on underneath your 2017 Ram ProMaster 2500 chassis with no drilling required. As you have the swing open doors I recommend using the Swing Away Adapter # SAR36VR which will allow you to access your rear doors without having to remove your bikes. For a bikes the Hollywood Racks RV Rider Bike Rack # HLY64FR is my preferred rack...

  • 2021 Ram ProMaster 1500 Trailer Wiring Recommendation for 4-Way and 7-Way Sockets
    To replace a 4-Way/7-Way connector on your 2021 Ram ProMaster 1500 you need the Hopkins Socket Kit # HM40975. Otherwise, if you're needing to ADD 4-Way and 7-Way sockets then you need the following parts: - Curt T-Connector Vehicle Wiring Harness # C58DR - Universal Installation Kit # ETBC7 - No-Drill Mount Bracket, Long # 18136 - Extra 10 Gauge Wire # 10-1-1 (on an as-needed basis) If you also need a brake controller then I really like the Redarc Tow-Pro Liberty Brake Controller...

  • Recommended 7-Way Connector and Hitch for a 2021 Ram ProMaster 1500
    Yes, the Universal Installation Kit for Trailer Brake Controller item # ETBC7 does fit the 2021 Ram ProMaster 1500 so long as you have a 4-way wiring harness installed like the Curt T-Connector Vehicle Wiring Harness item # C58DR. The item # ETBC7 kit includes a pre-wired 7- and 4-way trailer connector that mounts easily at the rear of your van with an included bracket. This kit is designed for use on a vehicle with an existing 4-way flat trailer connector and plugs directly into it.  To...

  • How to Add 7-Way & 4-Way to 2022 Ram ProMaster 3500 Without Factory Tow Package
    We can definitely accomplish your goal, which is to have a wiring connector on your 2022 Ram ProMaster 3500 with both a 7-way and a 4-way. While you cannot use the # C58DR without connecting it, the 7-way adapter you'll use actually has a plug on the side that allows a 4-way connection, as you can see in the photo I added. Since your '22 ProMaster does not have the tow package, the first thing you'll need to do is install a 4-way. And while the Curt T-Connector # C58DR will fit, I highly...

  • Recommended Hitch and Spare Tire Carrier for a 2019 RAM Promaster 2500
    I don't have a 2019 Ram Promaster 2500 in front of me so you're going to need to take a measurement of yours to confirm that the Roadmaster Spare Tire Carrier item # RM-195125 won't block the doors when connected to the etrailer Hitch item # e99AR. The top of the receiver sits 2" below your Promaster's rear bumper. You'll want to open your door and measure from 2" below the bumper to the bottom of your door. If this is less than 7-1/2" you'll have plenty of clearance. On the Roadmaster...

  • Recommended Trailer Hitch Receiver For a 2023 Ram ProMaster 3500 Extended With Super High Roof
    I recommend installing our etrailer Trailer Hitch Receiver # e99AR on your 2023 Ram ProMaster 3500 extended with the super high roof. This receiver mounts behind the rear bumper beam and will fit both the extended and non-extended models. I prefer our receiver as it has a matte black finish which I find looks better and is more durable over time. We do have the Curt T-Connector Vehicle Wiring Harness # C58DR which will give you a 4-way flat wiring connector which is commonly needed for...

  • Can You Use Other Battery for Curt T-Connector Vehicle Wiring Harness On 2018 Ram ProMaster 2500
    The Curt T-Connector Vehicle Wiring Harness part # C58DR which is a fit for a 2018 Ram ProMaster 2500 requires a battery connection for power. The battery connection is actually what powers the trailer lights, the t-connectors just pull signal from the vehicle lights, not power. The power must come from a battery, preferably the vehicle battery which gets frequent charges from the alternator. That said, if you want to use a separate battery you have in the rear there will be no issues with this.

    The Curt Trailer Hitch Receiver # C13295 will fit the 2021 Ram ProMaster 3500 Extended chassis under your 2022 Winnebago Solis 59PX. This receiver has a 500lb tongue weight rating which is enough for your 350lb motorcycle and Carrier # e98873.
