Video Transcript for Hopkins Wiring 37995 Review

Today we're going to review part number 37995, this is the Hopkins 6-Pole Square Trailer Wiring Connector Kit. You can see it has the square design 6-Pole on both connectors. It includes the male end, the male end is what would go on the trailer and includes the female end, 6-square end, which will go on to the vehicle. Basically the pigtail wires on each, they use an 18 gauge size wire. The length, give you an idea of the length on these, got a 12 inch ruler and basically you can see that you're about 12 inches in length on each one. Now basically what you would do is this one here, with the female end, this would connect to the vehicle, the tow vehicle, so you'd wire this in with the pigtail wires. This end, with the male ends, would go to the trailer, and again you'd wire those in.

Then basically all you would have to do is push that together, just like that, and you would have the six way connector. That should do it for the review on part number 37995, the Hopkins 6-Pole Square Trailer Wiring Connector Kit. .

This product replaces several of types of connectors, e.g., cinch-jones and other 6 wire types. It will be used to connect model railroad show modules. I was looking for a reasonably rapid insertion and disconnect and good conductivity. Power is low power DC, so the wire is more than adequate. I also needed a reasonable drop so as not to strain the terminal strip (barrier) connection. These, I believe, will work well. I hope this helps. 94467





Comments

The connector sets I purchased are for inter modular connection on a mobile model railroad. They are working very well. I would hope you might make a connector with more pins, e.g., 8 or possibly 10. I realize the trailer application requires only 6, but the ledger ones might find other applications.

I recently needed a simple trailer plug for a motorcycle. I shopped for the product at a couple of major stores and could not find a six prong connector. I could have kept looking and probably found it but I went to etrailer.com and found it cheaper even with shipping than I could have bought it locally. Thanks etrailer Dan 146062

Arrived in a timely manner. Ordered at the end of one weekend and it arrived well in advanced of the next. Product will be used as an in-between from my pickup and it's cap (topper). I have a few extra lights and electrical accessories that need to be disconnected when the cap is removed. This one plug makes it simple. 126736

  • How to Make a 6-Way Square to 4-Way Flat Trailer Wiring Adapter
  • The 6-Way square trailer connector is not used by a lot of trailer manufacturers. A lot of Jayco trailers may have them but mostly you come across the 4-Way flat, like what you have on your trailer, and the 7-Way blade for RV applications. What I recommend is to convert the 6-Pole on the Monaco to a 4-Way. You can do this very easily by removing the 6-Way plug, and then testing the wires for function using a circuit tester like # 3808 if needed before installing them in a new 4-Way,...

  • Installing a Brake Controller on a 2010 Hyundai Santa Fe with Factory Tow Package
  • To install the Tekonsha brake controller on your 2010 Hyundai Santa Fe, you will first need a 4-Way trailer connector if you do not already have one. The Tow Ready Custom Fit Vehicle Wiring, # 118258, that you have referenced will fit your Santa Fe if the Hyundai Santa Fe came with Factory Tow Package. If it did not, then use harness # 118415. I have included a link to the installation details below. I recommend switching the plug on the trailer from a 6-Square to a 7-Way. You can use...

  • How to Make a 7-Way to 6-Way Square Jayco Trailer Connector Adapter

You will need to make one using the follow parts: 7-Way trailer connector # H20042 6-Pole Square Trailer Wiring Connector Kit, # 37995 Start by identifying the wire functions of the trailer side connector so that it will be easier to wire in the 7-Way later.

I recommend starting with the 6-Pole Square Trailer Wiring Connector Kit, # 37995. You will need the end that plugs into the vehicle side to make an adapter. You can then use Quick...

  • Connecting a Coachman Pop-Up Trialer with 6-Way Square Connector to a Vehicle with a 7-Way RV

You will then have the functionality needed to provide power to the trailer brakes and have power to maintain a battery on the trailer if it is so equipped.

If you do not wish to do this, you could fabricate an adapter using a 6-Way Trailer End Connector, part # PK11604 and a 6-Pole Square Trailer Wiring Connector Kit, part # 37995. You will want to make sure to wire the connector so that the vehicle and trailer side are wired identically. LOCATE WIRES BY FUNCTION ONLY White...

If you convert the trailer, the other 2 functions on it will be lost unless you converted it back again. If you converted the vehicle, it will only be compatible with trailers that...

  • Yes, you could use the 6-Pole Square Trailer Wiring Connector Kit # 37995 on your 1998 Jayco Pop-Up trailer. If you have a 4-way on your tow vehicle you may also be interested in purchasing a Adapter 4 Way Flat to 6 Way Square for Jayco # 30104. With this product you could just plug this into your tow vehicle and then into your trailer and you would be ready to go. By doing this you will lose 2 functions of the trailer wiring, most likely one of them being a 12-volt power source.
