Video Transcript for Pollak Wiring - Wiring Adapters - PK12-724 Review

Today, we'll be reviewing part number PK12-724. This is the Pollak Trailer Connector Adapter, has a 7-pole round to 7-pole flat. This adapter is going to convert your 7-way round pin vehicle end connection for use with the 7-way RV style trailer end connector. It's going to let you tow a trailer with a 7-way flat plug, and it's going to work with any RV style 7-way plug. It also connects the ground, left turn, right turn, and stop circuits. Here on our plug, we have round floating solid brace pins. This is going to ensure minimum voltage drop, and it's going to align very easily for maximum contact.

Here on our socket, we have a spring-loaded hinged door that's going to protect the interior from dirt and moisture. We also have this nice collar with 4 mounting holes that's going to let you mount the socket to your bumper. The plug is constructed of glass-filled nylon, and the socket is constructed of high-impact ABS thermoplastic. The overall length of our plug, when we stretch it out, is going to measure right at 16 inches. The length between the plug and the socket is going to measure right at 7-1/2 inches. A couple of different wire gauges that I want to give you is we have this nice plastic coating that goes over our wires to help protect them and keep them to of harm's way and from getting damaged, but the white wire is going to have a gauge 8.

The red and blue are going to be gauge 10, and the black, yellow, green, and brown are going to be gauge 12. That's going to complete our review of part number PK12-724, the Pollak Trailer Connector Adapter, 7-pole round to 7-pole flat. .

Rather a difficult set up to find. Tried calling several other vendors, and most weren't able to fully comprehend what it was I needed. Called etrailer and not only were they able to know what I was talking about, they had it in stock and I had it in my hands within two days. Personnel are always superior in every aspect of customer service and basic human interactions. Which has become far less of a normal occurrence in this world. I will continue to use etrailer and spread the word on their great performance and excellent product lines. 476010

We are so glad we found etrailer.com! We have never ordered an incorrect part because their info - and large bank of Q&As - has always told us everything we needed to know. I wanted to share our experience with the Pollack 7-way blade to 7-way round connector, part PK12-724. When researching for the correct part, we found a question from a buyer who had the same/similar vehicle, a 1993 Ford F-150 with a factory tow package. He was told to buy the PK12-724 but to cut the red and blue wires and cross-connect them. (This was info we we so glad to have!) We did so, and most everything worked except the trailer back-up lights came on whenever the lights were turned on. We mentioned it at the RV place when we were there, and they checked it for us. Turns out that not only did we have that issue, but our trailer battery was not charging when hooked up and truck running. So on the blade end of the connector, they moved some of the wires around (see included illustration), and voila, everything now works correctly! I hope this is helpful to others. I believe the truck information is the most important info for this fix, but FYI our Trailer is a 1994 Komfort 27. 441427

This is a great solution for adapting RV blade connector to 6 pole connector. I give it 5 stars. I use this for work purposes, and have found one issue that I DON'T believe to be manufacturer defect. In my industry we use different trucks and trailers daily, if not hourly. Some trailer electric brakes will lock up when adapter is connected. I have found the red wire in the adapter to be the problem. My solution was to splice in a switch so that when the intermittent problem arises I can flip the switch and be on my way. 515426


Comments

Thanks for the information Charles, I did want to let you know that there are two differnet wiring configurations for these 6-way connectors. Sometimes the red wire that you noted as the brake connector point can also be pinned as the 12V power wire. This would then activate the brakes, as you noticed. Your solution while it worked for your application is not something that we generally recommend for our customer in case they forget to flip the switch and are then towing without brakes on their trailer. For that instance we recommend repinning the connector and changing the 12V and Brake pins to correspond to the correct functions.

  • Hooking a Gooseneck Trailer with RV 7-Way Plug to 1999 International 9100 7-Way Round Plug
  • The first thing that you need is the Pollak Trailer Connector Adapter # PK12-724 which converts the 7-Way round connector on your 1999 International 9100 to a 7-Way blade style connector. This will plug into your 9100 and provide a pace to connect the gooseneck trailer wiring. The next step is to then use the Roadmaster Brite-Lite Wiring Converter # RM-732 on your trailer side wiring right behind the 7-Way. This converter takes separate brake and turn signals and combines them so that...

If you need the 7-blade to 7-pin adapter, I recommend the Pollak Trailer Connector Adapter - 7-Blade Plug to 7-Pole Round Pin - Nylon # PK12727. If you need to go from pin to blade, you can use # PK12-724 or # HM47425. There is one other style that is a fit for your truck, but it is not very common. If you are looking...

  • Adapter Recommendation for Going From 7-Way Round to 7-Way Blade
  • We have two adapters to go from a 7-Way round pin on a tow vehicle to a 7-Way blade style on a trailer. You could use either # PK12-724 or # HM47425. Either would work well for you if your tractor has trailer wiring setup for combined turn signals where the blinkers and stoplights are on the same circuit. If they are separate then you would need to install a second 7-way blade as that would be the easiest way. For that you would need a 7-way like part # 37185 and a signal converter like...

If you take a look at the accompanying photo, which is from our linked article on trailer wiring you can see that the connector on the left has blade-style pins while the one on the right has round pins. There is even an adapter, the Pollak Trailer Connector Adapter # PK12-724, which is a 7-pole round to 7-way blade if you need to go from the uncommon 7-way round to more common 7-blade.

  • There is an adapter to go from the 7-Way round pin connector on your 1993 Ford F-350 to a 7-Way blade style connector for the trailer. It is Pollak Trailer Connector Adapter - Vehicle End - 7-Pole Round to 7-Way Blade Item # PK12-724. Assuming that your 7-Way round pin and the 7-Way in your truck bed are both wired to each other (which is very likely) all the functions, including the brake output circuit, will function when using this adapter.

  • To convert your 7-way round connector to the 7-way blade style connector on your trailer we have Pollak Trailer Connector Adapter part # PK12-724. To use this adapter you should not have to splice together your separate brake light circuits on your Ford F-750. The power output at your 7-way trailer connector on your truck should already be wired as the diagram I have provided. I recommend using a circuit tester to test the pins of the 7-way trailer connector on your Ford truck. If your...

Because of this unorthodox setup there isn't a single cable available that will connect the trailer to your Ram but we do have the pieces needed to do this. In order to connect your Ram to the trailer you can use a 7-Way loop like the Bargman # 50-67-210 and then an adapter like the...

Basically you will need to convert either the truck or the trailer. Converting the truck is easier especially if you are not going to be towing any big rig trailers. If...

If by chance your tractor has separate taillight wiring, meaning that the turn signals and brake lights run on separate pins, you will need to add a converter, like the Tow Ready, # 119130.
