Installation of Tekonsha T-One Connector
This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located in your rear cargo area. You will have to remove the access panel doors to access this harness. Once you've plugged in the T-connector, run the body harness up to your car battery and connect the wires per the included instructions.
Once installation is complete, the 7-way connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.
It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 7-pole connector itself - to help prevent corrosion.
ModuLite Powered Tail Light Converter
A ModuLite power module is built into this T-One connector. Because most trailers run on a 2-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's 3-wire system need to be combined so they are compatible with the wiring system of your trailer. This power module functions as a tail light converter to combine 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.
With a ModuLite, your trailer's lights will be powered without overloading your vehicle's electrical system. Because the module draws power directly from your car's battery and bypasses the electrical routes that are used by a basic wiring harness, there is virtually no draw on your tail light circuits.
Installation of Tekonsha Brake Controller Adapter
This adapter plugs into the 4-pin connector on your vehicle's built-in brake control wiring harness. The harness is located near the steering column, through a grommet in the engine compartment.
This adapter requires no hardwiring. It is designed to plug directly into your electric brake controller for the simplest installation possible. Because there are no wires to connect, installation is not permanent. You can unplug and remove your brake controller at any time and securely stow it away.

2016 Ram ProMaster 2500
I purchased the wiring kit, brake controller and extra bracket for my 2016 Promaster 118. The install went great. I used another stainless steel bracket to attach the 7 way to the bumper cover. It looks good and totally professional. The brake controller sits just below the fuse box and is out of the way but accessible. I did route my power wires going to the front beneath the van. I drilled a 1/2 inch hole through the rear plastic of the battery box to bring those wires in.

This is one of the easiest trailer brake & trailer light wiring kits to install. The plug and play connectors makes it a breeze. The video provided matches what you actually have todo identically which made it even better. I was two connectors short but other than that everything I needed was provided!
by: Craig03/05/2023
Good product. Has held up. I had two Curt wiring harnesses fail before installing this one. It's been good through two winters.

2019 Ram ProMaster 2500
Would rate this higher but the instructions are lacking key detail about tapping into the brake pedal wire which is absolutely critical for this to work properly. There is a small red wire that comes off the brake control harness. in the instructions it simply says "connect to negative side of brake switch". which is totally vague and it gives no further details or photos. I had to do some online research work to find out you need to tap into the green and white wire that is above the brake pedal in a factory 4 wire harness. its all the way on the end. connect the red wire to that wire and you are good to go. This should've been explained better in the instructions that come with it as it took a lot of time and headache to figure out on my own.

YES...YES...YES...My Ram Promaster 1500 did not have factory installed Trailer light system. I contacted a nationally recognized trailer/hitch company to install my system and after 7 hours of my wasted time/money, they failed to do it correctly. I had used a similar product to this in the past and it worked well so I ordered this one as I upgraded to electronic brake controller. Came with EVERYTHING needed. Complete instructions. PERFECT PRODUCT...PLUG AND PLAY...Just make sure you order the correct one for your application (4 pin, 5 pin, 7pin) and adapters if needed. I operate in harsh environments of heat, cold, dust, off road... so I also use the dielectric grease on all connections . Wires are also protected by secondary abrasion protection outer wrap...Does not get any better than this. Dont buy cheap knock off wires at your local auto store...do it right, your pulling valuable equipment and have a responsibility to tow safely.

The website is easy to look at and explains what you need to know. The delivery took some time but it was because we were waiting on one of the parts. Someone emailed me and offered a different product so that we could get our delivery faster. We didn't need the parts that fast so we just waited for the original part. Overall a great experience.

- Comparing Trailer Hitch Options for a 2019 Ram ProMaster 2500The trailer hitch options for a 2019 Ram ProMaster 2500 can be broken down into two categories, hidden and visible. The hidden options do not have a crosstube under the bumper and the visible option does. The hidden crosstube is harder to install. If you prefer aesthetics over install difficulty then go with the hidden but if you prefer an easy install over aesthetics then go with the visible crosstube. I prefer Curt hitches so part # C13207 for visible or part # C13295 for hidden. The...

- Recommended Hitch and Wiring Harness for a 2022 Ram ProMaster 2500The best hitch for your 2022 Ram Promaster 2500 is going to be the Curt Trailer Hitch item # C13207. This hitch is custom fit and bolts to your Ram with included hardware. It has a 2" receiver with a 6,000 lbs weight capacity that can be increased to 7,500 lbs when used with a weight distribution system. For a wiring harness that controls both your trailer's lights and brakes you will want the Tekonsha Vehicle Wiring Harness item # 22112. This custom fit harness plugs into your existing...

You can run it through inside of the vehicle interior or you can run it on the outside like we did in our install video. In our experience we found the outside routing to be easier so that would be what I would go with for you. I attached an install video for this for you to check out.
view full answer... - Fit of Draw-Tite Class III 76050 Trailer Hitch On Extended Model 2020 Ram ProMaster 3500According to Draw-Tite, their # 76050 Class III hitch is a fit for the 2020 Ram ProMaster 3500 Extended model. For a trailer wiring harness on vehicles without the tow package, use # 22112 or # HM40975-11933 for tow package equipped vehicles. For a ball mount, use # C45230 along with the # PC3 hitch pin. For a 1-7/8 inch trailer ball, use # 19260 or # 63845 for a 2 inch ball. I've linked to some installation videos that you might find helpful.
view full answer... - Recommended Trailer Hitch, Wiring Harness, and Brake Controller For 2021 Ram ProMaster 3500I would be happy to help! For your 2021 Ram ProMaster 3500 standard length you will need a trailer hitch receiver, a vehicle wiring harness, a ball mount, hitch ball, hitch pin and clip, and a trailer brake controller. Starting with the trailer hitch I recommend going with the Curt # C13207 due to it being the easiest hitch to get installed, but also due to it being tied with the Draw-Tite # 75882 for the highest ratings at 750lbs tongue weight and 6,000lbs trailer weight or 750lbs tongue...

If you want to use the P3 # 90195 then you will need to use the kit # ETBC7 to hardwire it. If you don't have the factory tow package, you will also need the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118618. If you want the complete wiring harness that also will include that brake controller wiring I recommend the Tekonsha OEM Replacement Vehicle Wiring Harness w Brake Controller Adapter -...

It doesn't require any drilling so installing it is super simple. It's rated to tow up to 6,000 lbs and 600 lbs tongue weight. For a wiring kit that comes with everything you'll need to install a fully functional 7-way connector, the Tekonsha # 22112 is the way to go.

- Best Trailer Hitch For A 2021 Ram ProMaster 2500 That Can Install Around The In-Use Grounding BoltIf the grounding nut/bolt are being used on your 2021 Ram ProMaster 2500, you are correct in that the Curt # C13207 will not be the best option for you. With that said, I recommend going with the Curt # C13295. This will install behind the bumper beam (pictured) and will not get anywhere near that ground. This is also American made and will give you 5,000 pounds of towing capacity and 500 pounds of tongue weight. If you were planning on using the hitch for towing, I also recommend getting...

Instead I recommend the Draw-Tite Max-Frame Trailer Hitch Receiver - Custom Fit - Class III - 2" # 75882 which is also confirmed to fit your 2020 Ram ProMaster 2500, but the hitch only goes on the bottom of the frame rails and not the sides so it will...

Now you will need to find the cold side of the stop light switch that only has power when the brake pedal is pressed. Using a circuit tester # PTW2993 will help you find the correct wire.

First you will need to install a wiring harness which will end up being part of the 7-Way connector installation.

If you do have trailer brakes you would need the # ETBC7 instead of the # 37185 and a brake controller. This kit comes with everything needed to wire up the 7-way and install a brake controller.
