Today we're going to review part number 30637. This is the Tow ready 4-Way Flat to 6-Way Round Pin Connector Adapter. Now, this adapter will convert your 4-pole wiring on your tow vehicle to a 6-hole round connector on your trailer. There are additional leads for the brake and for the power and also the white is for the ground. These can be connected to allow for electric brakes and accessories. Now, if you do have a, the 4-way right here would plug into the 4-way on your vehicle. Now, if the trailer has a 6-way and you just wanting to use the lighting functions, you can just plug in this 4-way and it would give you the lighting function.
You will still have to install this white wire with the eyelet to a big clean ground to get those functions to work. But, if you're wanting to use, I had an electric brake controller or any other 12-volt accessories, you do need to install these other 2 wires. Basically, what you would do is after you take the white wire and install it to a good clean ground, go to the blue wire. The blue wire is for the electric brakes. What you need to do, this would be routed under the vehicle using extra wire and then attach it to the blue wire on the brake controller. The black wire would be for 12-volt power.
This would have to be attached to a black wire and then routed under the vehicle and attached to the positive battery termining 00:01:24 with a 40-amp circuit breaker. Once you have that all hooked up, then you could plug in the 6-way on your trailer and get all the lighting operations, electric brakes, and still have 12-volt power. Length on this, to give you an idea of the measurement, lengthwise from the end of the 4-way to this about 15 inches in length. That should do it for the review on part number 30637. The Tow Ready 4-Way Flat to 6-Way Round Pin Connector Adapter. .

Tow Ready adapter converts your 4-pole wiring harness on your vehicle to 6-pole round connector.I ordered SEVERAL products. As usual, they arrived in a timely manner, and well-packed. By ordering a Four-Flat to a Six-Round Adapter, I saved myself a lot of time trying to make one myself out of separate components. I needed this adapter to utilize my trailers on vehicles that Don't have Six-Round lighting connectors. This adapter is very well made, and functions perfectly! I also ordered some Four-Flat connectors so I can use rental trailers of a larger capacity or "Car haulers" that don't have Six-Round connections. ALL products purchased are excellent quality. Thank You E-Trailer!
Sgt. L - 02/14/2018I purchased this adapter to enable me to connect my vintage tent trailer. The wiring kit that came for my car had a four pin flat connector so that worked perfectly with this adapter. I just had to run the 12 low-power and I was good. The adapter appeared to be well constructed and everything so far tests out fine.
Very nice to deal with you folks. You site is carefully put together. Very clear formation and it was easy to make a choice. It was the correct part and did the job. I think you guys decided from the beginning to be the best at handling tedious problems with trailers and their saftey. Thanks for your good work
William C - 04/25/2018I purchased this along with factory wiring connector for my Chevy K10- that was a breeze to click into the factory harness. I was having issues with the wiring job from before, i cam across Etrailer and found these quick install harness to fit my needs. it took less than 15 minutes to click in to space. i mentioned before, Cheaper than the local Trailer shop and no splicing. Good quality, on time delivery, easy to install.

Perfect for my Dodge. I tore a rats nest out and did a nice clean installation. I ought the 4->6 pole adapter and spliced in the battery and brake lines to the provided butt splices. Very easy! Whole job took 45 minutes including getting the bleeding stopped where I banged my head on the frame rail of the truck.
First time purchaser. Very prompt service by following up via email, and quick shipping. Product came packaged very well and in excellent condition. I will be cataloging this website for future purchases. Have already recommended this business to friends.
This item will be used to connect the lights/brake between our motor home and 2016 GMC Sierra 1500. Received the item fast from etrailer. Would recommend etrailer to family and friends.
Edward P - 05/06/2017This product work perfectly. We just got a new camper and old one had 4 plug and the new one is 6 plug. This workout great.
The description online was very accurate and easy to purchase. The product we bought was exactly what we needed and received it in just a couple of days. I would diffinately recommend people to shop at etrailer.
I was so pleased with etrailer.com! My wife and I bought a camper and had no way to hook up the lights. Our product was delivered quickly so that I can go pick up our camper.
I was told to check out etrailer for all my needs anything for my trailer and like WOW!!!! They actually had what I needed and shipping was fast. It works perfect with NO issues at all. Thanks guys for your help on this and I will definitely order again from you.
As a small business owner I am extremely pleased with the service and follow up that you provide. Making yourself available to your customers is very important. I also find the how to videos very helpful. I will highly recommend you to anyone who is in need of your products.
Work perfect. This Adapter worked perfectly for what I needed. Seems to be heavy duty and durable. I'm using it for a Stock trailer to pull a horse. It was really helpful the way this site is set up. By having the customer tell them what type of plug from the Truck and Trailer, it advised me the exact plug I needed. No other auto supplier, Wal Mart or anyone I asked could get me the right plug.
I used this with a Ford Ranger adapter. It hooked right up. I didn't see that it didn't have the bracket to attach to my pickup. I bought one at an auto parts store. It was easy to attach and works. The price was the cheepest I found, shipping was great. Etrailer is great to work with. I will shop here again.
Product worked as advertised. Did not utilize the brake wiring (didn't need to for my application). If I choose to keep permanently hooked on my 04 Pilot, will require some mounting hardware since tralier hitch doesn't really have anywhere to put it.
I have several vehicles that required the installation of this adapter. I have had at lease two of them installed and in each instance these were quality items that fit perfectly and performed well.
Installed on Blu Ox tow bar yesterday. & plugged in to tow daddy wiring kit perfectly.
All of it was high quality and fairly priced. It's already installed, It would be nice to have a bracket option to mount the six pin socket to the hitch. I ran a hole on the passenger side flat metal bracket.
Only place I could find this hook up! Drove about $15 worth of gas going to the usual auto parts stores. No one had it. Came to etrailer, bang! Instant find (with help from a fella that put me right on the product number). Fast deal, fast shipping, exactly what I needed!
I had to give you this praise too! Great website! My son and I have both ordered recently! Fast, cheap shipping! Products worked AWESOME!!! Thanks! The wiring harness for his Dakota was awesome. The adaptor was even easier!
Have received but have not installed. Quality of product is very good.
Doug W - 10/14/2018Very good quality & arrived in a very timely manner. Hard adapter to find,
