I wanted an adapter that was more difficult to lose. Red helps. I wanted an adapter that told me if I had power. it does. I like the cap for the 4 way. 481392

Fantastic customer service. Have bought many items from this store. This item was delivered, but I never received it. The company immediately shipped another part out and was received just in time for our needs. Using this adapter to go from 7-pin to a 4-pin to haul a pop-up camper. Will Definitely do business with this vendor again!!! 718122

Product works as advertised and allows me to plug into my more reliable weather sealed RV plug to power my trailer lights. The only downside is that I will need to get an extension to reach the plugs on some of my trailers. Overall, however, a removable adapter is a good solution to chronically corroded flat four connectors that hang on the back of my truck in tough Upper Michigan winters with heavily salted roads. 524697

Work's great for what I need it for. Awesome delivery time also. 422608



- 37335
by:

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

Ask the Experts about this Hopkins Wiring

  • 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.

  • 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 # 40376 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...

  • No Trailer Lights Using Adapter 7 Pole to 4 Pole # 37335
    Adapter 7 Pole to 4 Pole # 37335 isn't fused but it is possible that something happened to the wiring on the inside. I recommend taking it apart and inspecting the wiring and fix as needed. Or replace it with a different adapter such as # 78117 if you still want one that lights up. Or for a regular adapter # PK12716 is a popular option.

  • 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...

  • 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...

  • Troubleshooting Trailer Lights Not Working Using Hopkins LED Night-Glow Adapter
    That is very likely the case. With that being said the Hopkins adapter # 37335 doesn't use all of the lighting functions to light up so you need to test it to be sure. Use a circuit tester, like part # 40376, to test each pin coming out of the adapter. Run through the lighting functions on the truck as you test it to see if the pins all work there. If they do the problem is on the trailer. If they don't work then unplug the adapter and do the same test on the pins of your truck's 7-way....
