Would have been an Easy install except when you have had your truck (2018 , 1 ton SRW) undercoated. It still, overall was an easy install, just took an extra 30 minutes. Coating was covering the bumper plug. I would recommend this product for a DIY. Transgender.

This product has been excellent. Makes the hook up of lights so easy. No problems whatsoever. Pro hint: Use dielectric grease on all contact points.
Installed with bed liner in truck. Cut out for the rails.it took me all day to install by myself I took extra time for measurements. Drilling new holes and torquing bolts wasn't bad. I suggest having a helper to do the drilling and torquing. Great product. Would recommend.

Harness has worked exactly like it was supposed to. Allowed me to hookup in the bed instead of the bumper. Forget it is there until I need it and have had zero issues. Great product!!

Part worked great and the team at etrailer was great! Highly recommend.
Super product and easy installation.
Install was very easy, wish it would come with some of that gel you’re suppose to put inside of it. Just needs a little and no need to buy a whole big tube of it. Haven’t used it yet but was everything I needed for my Fords new gooseneck. Didn’t want to plug it in at bottom of bottom of bumper

Thanks for all the photos, Aldine, they're all great shots! I'm happy to hear that the install was easy for ya. Are you going to be hauling a 5th wheel or a gooseneck with your truck?
The directions and pictures were very detailed. Shipping was fast and they communicated at every step.
Great Customer Service!
Installation was very easy and straightforward. It took about 10 minutes; once the spare tire was out. The hardest part was taking out and putting back in, the spare tire. If you have a 5th gen Ram that didn’t come with a gooseneck plug, there should be a plastic cover where it would be. Pop that out and your hole for the wiring is already there. There will be four small squares in the corner. The plug that is mounted to the firewall has enough clearance, so you can mount it to the bed using the provided self-tapping screws.
I purchased this unit after reading the reviews. I received both the C56070 and a B&W OEM hitch within a few days of placing my order. Etrailers’s customer service is excellent! The installation of this wiring harness took about twenty minutes including cutting the hole for mounting. Everything but the hole saw was included in the package! I am very pleased with my purchase!
Be sure to watch their installation videos prior to purchasing, they give real insight into the process!
The plug in is located in the bottom left corner of the photo!
Great product! a 10 for sure.
The 7 foot cord was more than adequate. Good quality product. I installed on 2019 Ram 2500 Big Horn.
I will tell you dont even try the install without lowering the spare tire. Even if you are able to fish the wire over (like I did) you will not be able to make the connection to the existing 7 pinn on the bumper. the plug adapter is wired in such a way that you cannot get your hand and the wire in the right orientation. The install of the unit will be less than an hour and probably closer to 30 min.
One last tip, when reinstalling the spare be careful not to push the tire to far to the front there is a thin metal shroud that the tire will rub on and squeak over every little bump. test it before you are done, ask me how I know. LOL
Plug and play. Only 1 hole drilled to mount it
Perfect fit. Plug and play application; easy to install.
This harness is excellent. It plugged right in and looks like it should last a while. It also included plenty of zip ties and the necessary mounting screws. The hardest part was mustering up the nerves to drill a 2-1/8” hole in the bed of your truck. After drilling the hole, I put touch up paint on the bare metal to prevent rust. I also put silicone sealant in the screw holes, after they were tapped, to seal the metal there too. Install was quick and easy with the right tools; just the hole saw and a drill driver with the appropriate socket for the mounting screws.
Fast shipping and really easy to instal l.
Plug and play - so nice having an extra outlet in the bed of the truck!
As usual the ordering at etrailer.com was fast and easy. Shipment was fast and delivered on time. The 7way extension for gooseneck was as advertised. The toughest part of installation was feeding the end of the wiring harness through the post channel. Had one of these on my previous truck and missed it on my new truck. I recommend this product and etrailer.com

Easy install. Happy with the purchase!
Super fast install. Great product. I have a 21 Ram crew short bed and the 7’ is the way to go. 35 min install. Tested and works great. Instructions call for a 2-1/8 hole. I was able to use the 2” hole saw and remove and reinstall the grey plastic wire cover from the Y.
