Video Transcript for Hopkins Wiring 37335 Review

Today we're going to be taking a look at part number 78117. This is the Hopkins trailer connector adapter with Nite-Glow LEDs. This is going to convert your 7-way RV style connector to a standard 4-wire flat vehicle end connector. It's going to let you tow a trailer with a 4-way flat plug. That's going to be the plug here on this side. It's going to have a nice dust cap that protects the connection points from any type of rust or corrosion and from the elements.

When it's not in use, you simply just place the dust cap back over top. This system's going to connect the ground, left turn, right turn and stop circuits. Again, it's going to let you tow a trailer with a 4-way flat plug. It will adapt any RV style 7-blade plug. Now this unit is going to be made from a durable corrosion resistant construction. Located on the inside are going to be the Nite-Glow LED system.

That's going to make the connector easier to see at night. The LEDs are going to be activated by your vehicle's tail light circuit. The LEDs are going to appear red because of the red clear housing. We're going to take a measurement of the overall length measuring from edge to edge. It looks like that's going to give us a measurement of about 3-3/4 of an inch. I'm going to go and connect some power to this so you can see what the LED system looks like.

We'll simply just make our connections here. I'm going to turn off the lights so you can get a better view of it since this is for low light settings. You can see there that it sends out a nice consistent signal. The clear lens allows a lot of light to come through so it's going to make the plug easier to see in low light conditions and it can definitely help make the connection a little bit easier to make. That's going to do it for today's review of part number 78117. This is the Hopkins trailer connector adapter with the Nite-Glow LEDs.

The product works but I found that when dealing with a difficult truck plug, the black inner part of the adapter likes to push into itself. This seems to be due to the outter red case being too soft and pliable. Needs to be a harder plastic and the use of screw ot two might help keep it in place 403708

  • 7-Way on Vehicle to 4-Way Trailer Plug Type Adapter for a 2004 GMC Envoy SLT
  • The Adapter 7 Pole to 4 Pole with Tester and Cover, # 47345, will fit your 2004 GMC Envoy SLT, as long as the factory plug is a 7-Way, blade type (and it more than likely is). We also have the Pollak 7 Pole to 4 Pole Connector Adapter, # PK12716. Another option is the Adapter 7 Pole to 4 Pole with LED Nite-Glow (TM), # 37335 (kind of neat as it lights up with the taillights). There are several more. I have included a link below that will take you to them.

  • Is there a 7-Way Adapter that Splits into Two 7-Ways or Should a Junction Box be Used
  • There isn't an adapter that does what you are looking for. I think the junction box idea is the best solution because junction boxes do make things nice and neat and make it easier to troubleshoot. One thing to keep in mind though is to be careful about how much power you are pulling through a set up like that. Most vehicle side wiring and wiring systems are not rated all that high so overloading them is a real possibility. Our most popular junction box is # 38656 but I have also included...

  • Can Two Wiring Adapters Be Used At The Same Time On 1994 Chevrolet Pickup
  • Using the 2 adapters together will give you the connector configuration you started with on your truck. The Adapter 7 Pole to 4 Pole with LED Nite-Glow, part # 37335, plugs into a 7-way connector on the vehicle and gives you a 4-way flat connector for a trailer or other items that has a 4-way trailer connector. Using the second adapter like part # 30717, which is similar to the 47205, would just reverse the first adapter. It would need to plug into a 4-way connector on a vehicle...

  • Adapter 7 Pole to 4 Pole with LED Nite-Glow Does Not Light when Plugged Into a 2015 Toyota Tacoma
  • There could be a short or blown tow package fuses on your 2015 Toyota Tacoma causing the 7-Way to 4-Way adapter # 37335 not to light up. To determine if that is the problem you can use a circuit tester such as # 3808 to test the connector on the truck without the adapter plugged in. If the pins all have power when they should (head lights on, turn signals engaged, brake pedal pressed) the plug in the adapter and test the pins on the 4-Way side. If there is no power on the 4-Way side...
