Replace the damaged 7-way, RV-style trailer connector on your vehicle with this T-One harness. ModuLite reduces strain on wiring system. Brake controller adapter plugs in beneath your dash and lets you easily plug in your electric brake controller.

Specs:
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.
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.
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.

Replace the damaged 7-way, RV-style trailer connector on your vehicle with this T-One harness. ModuLite reduces strain on wiring system. Brake controller adapter plugs in beneath your dash and lets you easily plug in your electric brake controller.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!
Nice products and has worked out very well. etrailer is a good supplier.
Good product. Has held up. I had two Curt wiring harnesses fail before installing this one. It's been good through two winters.
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.
Fit perfect.
This is the second set of Hitch, wires, and controls. Super easy just as advertised. They come in a reasonable amount of time and always in good condition. I recommend them to friends because I have had a great experience.
Everything went perfect from ordering to installation
Fits perfectly and the video of the installation was very helpful.
Extremely Easy install thanks to the great instructions.
Highly recommend etrailer.com
Great wiring easy to install and route glad to have videos for any possible issues wish the hitch fit better had to grind down bumper sides in order to get it to fit properly other then that all was as good as I can expect from eteailers good quality and fast reliable products
This was easy to install and the length was perfect. It did come short one ring terminal--you will need 4 and it only came with 3.
Just received and not installed yet but in unpacking the harness it feels quality and is/ was a great price for all it does.
Thank you etrailer!
etrailer beat competitors pricing and the product arrived very quickly! Great customer service!
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.

Works like it should and was not hard to install. So far no corrosion.
