Video Transcript for Hopkins Wiring - Wiring Adapters - HM47340 Review

Today we're going to be taking a look at the Hopkins 7 way rv to 4 way flat trailer connector adapter with the LED test lights. This adapter's going to convert your 7 fold blade style vehicle end connector for use with a 4 way flat connector on your trailer. Located right here are going to be the three built-in LED lights that are going to provide easy troubleshooting. These are going to light up to verify that the connector's receiving power from your tow vehicle, and the light's are going to be labeled. That way you can identify quickly the function of each one. Connecting the two units is going to be our wiring. The wiring's going to have a nice protected casing that goes over it. That's a braided cable covering that's to provide a larger range of motion for a more convenient hook up.

Then when compared to standard adapters, that's going to be a nice durable design. That material's going to resist shock, and it's going to protect the wiring from the elements. Here on the 7 way we're going to have the large, easy-pull grip design that's going to make installing and removing the plug very quick and easy; just fits right in the hand. It's got grips on the bottom: it's like a pistol-grip design. Then you can easily disconnect that or plug it back in, so that's a really neat feature of this unit. Here on the 4 way flat side, we're going to have the tethered cap; goes over the connection points when the plug's not being used. The connectors are made from durable plastic construction. The overall length, measuring from end to end is going to be about 10 1/2 inches long, and it's going to come with a terminal grease packet.

That way you can grease up the connection points and help keep them safe from corrosion. The unit's very easy to use. All you have to do is plug the adapter into the vehicle, make your trailer connection, and then simply check the lighting system for proper operation. When the right turn signal is activated, the LED above RT should activate. What I'm going to do is I'm going to go ahead and hook this up to power. That way we can go ahead and kind of see each function.

The first one I'm going to do is TM, which is going to stand for 'tail marker'. Those are our tail lights. When I activate that, you can see how that one lights up. That lets us know that, that signal is strong. Then we will do this one right here.

This is going to be LT. That stands for 'left turn'. Then if we do this one over here. That one's going to be RT. That's going to be for 'right turn'. Then when you apply your brakes, both RT and LT will light up. That's going to do it for today's look at the Hopkins 7 way rv to 4 way flat trailer connector adapter with the LED test lights.

Hopkins products are really good - Rewiring trailers with only Hopkins products. The sheath covering 7 way to 4 flat wiring, seems flimsy and would deteriorate in a short amount of time, leaving exposed wires. The 7 way lights up, as well as the 4 flat, insuring wiring is connecting and properly working. The product I wanted was on back order, which appeared to be more heavy duty, sheath. Customer Service helpful. Received within a few days. 703813

My old truck had a 4 pin harness, my new (to me) truck as a 7 blade so this adapter was the solution. It fits as is should and works perfectly. 572576

  • How to Use Light-Up Hitch Cover With 7-Way on 2019 Chevy Tahoe
    You can easily use the Chevy Bowtie LED Lighted Trailer Hitch Cover # 86062 in the hitch of your 2019 Chevy Tahoe with a 7-way.

This will give you a hitch cover that lights up when you turn on your running lights and shines brightly when you step on the brakes.

  • Driver Side Trailer Lights Not Working While Using 7 to 4-Way Adapter
    I would first remove the 7 to 4-way trailer connector adapter that you are using and test the driver turn/stop pin inside the 7-way with a circuit tester. If you get power here then plug the adapter back in and test the driver turn/stop pin inside this. If there is no power inside the driver turn/stop pin on the adapter then this has failed and will need to be replaced for which I recommend the 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket part # HM40975 as opposed to something...
