Video Transcript for Pollak Wiring - Wiring Adapters - PK12727 Review

Today we're going to be taking a look at part number PK12727. This is the Pilot Trailer Connector Adapter, 7-blade plug with a 7-pole round pin. This adapter is going to plug into your 7-way blade style vehicle connector. That's going to be this end here. Then it's going to convert it for use with a 7-way round pin-style trailer end connector. This is going to be made from a durable, non-corrosive nylon construction. The male 7-way blade style connector on the adapter is going to join with the female 7-way blade style connector on your vehicle. Then the female 7-way round pin style connector on the adapter is going to join with the male 7-way round pin style connector on the trailer. You can see here that it's going to have a spring-loaded cap, so it's always going to protect those connection points when the connector is not in use, keeping out any dirt or grime.

Which is going to prevent any corrosion from being able to happen to the plugs. It's also got mounting options here. This does not include a mounting bracket. That's going to be sold separately. It's got a nice cover design back here that's going to cover up the wires. Then it's going to flow right into the protective wire loom.

This is to keep the wires safe and away from damage. On this end here, this is going to be the end that plugs into the vehicle. It's got the nice finger tab, so it's going to be an easy grip design. I took some measurements of it, and the overall length measured about 16-1/2 inches. That's from end to end. The amount of wiring that we have from the back of this plug here to the back of this plug here measured 7-1/2 inches.

It's going to have a voltage rating at 12 volts. That's going to do it for our review of part number PK12727. This is the Pilot Trailer Connector Adapter 7-blade plug to 7-pull round pin adapter. .

Ordered this standard delivery on Monday and received it Wednesday afternoon. Good quality and is exactly what I was looking for. I am a transporter an occasional pull trailers with the 7 round plug. This will convert the 7-blade plug on my truck to the 7-round. 557030

I just received the adapter today. I hope to put it to use this weekend. I was very impressed with the shipping time, as it was ordered on a weekend and shipped out during the weekend with quick response and made it here through a holiday and snow storm. Shipping was expensive for such a light product and size of box. The actual adapter could use some tape on the male side to provide a better seal between plug and wires. 606750

Item was just what we needed. Our pickup has a 7 flat blade plug so we needed an adapter to go to an 7 pole round plug for our construction trailer. All our trucks have round pole plugs, but not the pickup. The adapter did the trick for us now we don't have to change ends when towing with different trucks. 193996

  • Adapter Solution to Convert Gooseneck Trailer to Fifth Wheel King Pin
    We have gooseneck trailer to fifth wheel king pin adapters that would work great on your trailer but it really depends on what type of gooseneck trailer you have now. For example if you have a square tube gooseneck you could use the part # BD028965030 or for a round tube part # PKG5-R25-IP. Or you could replace the outer tube as well and use the Bulldog # BD0289590300. For an air to electric brake controller the Hayes part # HA100400C is the kit you want. This ties into the air brake...

  • Can I Tow A Tractor Trailer With A Ram 3500 Cummins Diesel Engine
    It depends on how much the trailer weighs and how it connects. Your owner's manual states you may be able to tow up to 32,000 lbs and up to 6,000 lbs tongue weight with a factory fifth wheel prep package in the Ram. You still want to see what the fifth wheel hitch is rated for itself because you cannot exceed that weight. You also want to make sure the kingpin is the correct size for your fifth wheel hitch. Some trailers designed for semis have a 3-1/2 inch king pin. Standard 5th wheel...

  • Wiring Adapter to Convert 7-Blade Flat Trailer Connection to 7-Pin Trailer Connection
    The Pollak Trailer Connector Adapter - 7-Blade Plug to 7-Pole Round Pin - Nylon # PK12727 does have the ability to separate out the functions so they operate correctly with your 7-pin trailer. The manufacturer has done the work so you can simply have a plug and play adapter between your 2005 Silverado and your commercial style 7-pin trailer wiring. I've attached an article to assist with where the functions match up on each end of the adapter.

    We have exactly what you need for an adapter to go from the 7-blade connector on your vehicle to the 7-round connector on your trailer: - Pollak Trailer Connector Adapter - 7-Blade Plug to 7-Pole Round Pin - Nylon # PK12727 or - Pollak Trailer Connector Adapter - 7-Blade Plug to 7-Pole Round Pin - Die-Cast Zinc # PK12728 The only difference between the two is that one has a nylon construction on the plug and the other is a die-cast zinc.

  • How to Extend the Pollak Trailer Connector Adapter # PK12727
    All of the adapters like the part # PK12727 that you referenced would need to be extended in order to be 3 feet long. To do this you would need to cut the wires and then wire in a length of wire for each circuit so that it is long enough for what you need. I would recommend 10 gauge wire like part # 10-1-1 that is sold by the foot.

  • 7-Way Round to 7-Way Blade Adapter Recommendation
    The part # PK12727 is an adapter that does exactly what you described. It goes from a 7-way blade on a truck to a trailer that has a 7-way round connector. You might also consider removing the existing 7-pin connector from the trailer, and replacing it with the 7-way blade plug like part # A7WCB. The 7-way round pin is getting fairly close to being obsolete. The 7-way blade connector is much more prevalent.

For that you need the Pollak Trailer Connector Adapter - 7-Blade Plug to 7-Pole Round Pin # PK12727. I've added a link to a video review of this adapter for...

    It sounds like you need vehicle side connection using the Replacement 7-Way Connector # 74682. This will give you the blade style connection to match your trailer wiring. 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...

  • Solution for Towing Trailer with 7-Way Round and Separate Lighting with Ford F-350
    We actually do have wiring adapters available that go from a 7-Way blade connector on the truck to a 7-Way round on the trailer, such as with the Pollak # PK12727, however since the circuits are separated on the trailer side an additional converter would still need to be added and the adapter itself would likely need to be re-wired. For this reason I recommend going a different route. I honestly think the easiest solution is going to be to simply add a second 7-Way on your truck, using...

  • Adapter to Convert 7-Way Blade Style Connector on Vehicle to 7-Way Round Pin Connector on Trailer
    It sounds like your trailer has a 7-way round pin connector. For an adapter, I'd suggest part # PK12727. The adapter would plug into the existing 7-way on your truck, and provide a 7 round pin female connector for the plug on your trailer. You might also consider removing the existing 7-pin connector from the trailer, and replacing it with the 7-way blade plug like part # A7WCB. The 7-way round pin is getting fairly close to being obsolete. The 7-way blade connector is much more prevalent. I'll...
