Video Transcript for Pollak Wiring - Trailer Connectors - PK11720 Review

Today we'll be reviewing Part # PK11720. This is the Pollak Heavy-Duty, 7 Pole, Round Pin Trailer Wiring Socket. The zinc die cast seven-pole socket connects the trailer to the towed vehicle. It's going to feature the round floating solid brass pins. They're going to provide easy alignment and maximum contact as well as minimum voltage drop.It has the dielectric nonconducting grease coating on all those pins, which is going to protect it against the corrosion, and it's also going to provide rust resistance. A wide range of wiring gauges are acceptable, from 16 gauge wire to 8 gauge ground wire. Ground terminal will accept a minimum of 14 gauge with a maximum of 8 gauge, and all other terminals accept a minimum of 16 gauge with a maximum of 10 gauge. When mounted, it's got a nice slant design, so water's going to run off.

It's going to prevent moisture from building up, especially inside the connection points. It's got the nice stainless steel spring lid that's going to open and close very easily. It's also got the bottom lip that's going to extend for better plug support. It's got the two-hole mounting design. The distance from the center of one hole to the center of the other is going to measure 3", and those holes are going to measure 1/2" by 3/8 of an inch. This plug is going to be interchangeable with all competitive makes.

It's going to require a 2" hole diameter for correct mounting. It's going to give us a volt rating of 6 to 28 volts with a current rating of 40 continuous duty amps. The wiring configuration. The white wire's going to be for a ground. We recommend 10 gauge for that. Black is going to be for clearance, side marker, and identification. Lights.

The yellow is going to be for left turn and hazard signal. We recommend 12 gauge for both. Red is going to for stop lamps and anti-lock devices. We recommend 10 gauge wiring. Green is going to be for right turn and hazard signal, and brown is going to be for your tail rear clearance marker and license plates lamps.

We recommend 12 gauge for both of those, and then blue is going to be for your auxiliary circuit, and we recommend 10 gauge wiring. That's going to do it for our review of Part # Pk11720. This is the Pollack Heavy-Duty, 7 Pole, Round Pin Trailer Wiring Socket. .

I ordered the 7 pole socket (PK11720) and the rubber boot for it. (PK11761) Also a trailer end plug (PK11700) to fit into the socket. The items arrived on the exact estimated arrival date that I was given on the day of ordering. Wiring the plug and the socket was very easy. Each terminal has a small screw that holds the end of the wire in place. It is a simple matter of threading the screw out, putting the wire in the hole, and then tightening the screw onto the wire. The boot fits snugly onto the back of the socket. I used these parts to repair the power cable assembly to a truck mounted forklift. The parts are exactly what was needed to replace what had been damaged. The quality is good and the prices are excellent. I will use etrailer.com in the future when I need related items. I am very pleased. 403804

The metal body and good quality pins and connections make this one the only one for a professional job. Remember if you use dielectric grease and the rubber boot you'll never have corrosion in your connections . Dissimilar metals and weather are a bad combination. 213712

Excellent product! I bought this to replace the old, brittle, and broken plastic trailer connector on my 1973 aluminum camper. The plastic one stood out against the aluminum which I didn't like. So, I'm excited how this will blend in and look more natural. Besides aesthetics, this very sturdy and ruggedly built. It will clearly outlast the camper, no doubt. Will definitely buy again if I find myself with a different camper in the future. 358289

Excellent product! - have, over only a few years, steadily worked my way through progressively more durable trailer cable sockets. The last one was the Hopkins heavy-duty, or something to that effect. The plastic casing on it broke within three months. I'm really looking forward to putting these to the test - I'm a farrier - I pull a trailer every day; the traffic in this area means that I must rely on excellent contact between vehicle/trailer for turn / brake signals and functioning trailer brakes. Nothing less. These sockets are heavy, all-metal (zinc-coated - road salt shouldn't be a problem), with few / no seams. When the trailer end is plugged into the truck receiver - it's a nice tight fit, with no movement: it's locked in. There are only two drawbacks for the homeowner who is looking for the do-it-yourself package: if you are looking for a metal bracket that bolts underneath the truck bumper and holds this part - there isn't any. And no bolts, either. I don't know if they sell them for these - I didn't check. I simply manufactured my own. So far, I'm delighted with the product. 203673

Bought to replace a 12 year old Pollak identical connector that I removed and could not re-use due to wire connections on the back being corroded (road salt area). The 12 year old connector worked fine except the flip up cover was a bit stiff. The 12 year old connector was also made in USA. The new connector I just received is made in China. From the price, I had hoped it was still made in USA. It seems that most of the time I am disappointed with the newer imported China versions of products once manufactured in USA. So my expectations for this product to have a long life are not very high. 146341

  • Converting a Semi 7-Way Trailer Connector to an RV 7-Way Trailer Connector
  • There are a number of factors involved when converting a semi 7-way to an RV 7-way. Semis generally use a 7-pin round pin socket, similar to # PK11720. And RV style 7-way uses blades, like # PK12706. We do not offer any pre-made adapters to make this conversion that will carry all of the electrical functions required by the RV. Another thing to be aware of is fifth wheel trailers use a combined wiring system where the brake lights and turn signals are on circuit. Your semi connector...

  • Vehicle Side 7-Way Round Pin Connector for a 2015 Nissan Frontier
  • If you only need the vehicle side 7-Way round pin connector and already have all the wiring to attach to it on your tow vehicle you can use connector # PK11720. If you do not have the wiring already available on your 2015 Nissan Frontier then you will need a few parts. If the truck did not come with any kind of trailer connector you will need to start by adding # 118525. You will cut off the 4-Way end and attach the wires to the back of the new 7-Way round pin, see diagram. If the trailer...

  • Low Voltage on Pollack 7-Pole Trailer Connector Right Turn Signal Pin on a 2002 Toyota Sienna

You may need a new connection there so cut the wire, strip off some of the insulation, and reconnect after cleaning the connector. Do this for any of the wires that appear to need it. Also check the main ground from the connector to the vehicle. It should be attached to a clean and corrosion free bare metal surface. You can also try moving the ground to a different location...

  • Towing a Trailer with Electric Brakes with a Semi Tractor with Air Brakes
  • To tow your trailer that uses an RV style 7-way blade style connector with your semi that has a 7-pin connector, you need to construct an adapter that will also combine the brake signal into the right and left directional signal pins. This can be done by using a female 7-pin socket # PK11720 to accept the plug from the semi, a tail light converter # 119178 and a female 7-way RV blade-style socket # PK12-707E. The converter would be wired in between both sockets to combine the brake...

However, if you already have a 7-Way round connector you can just use an adapter to go to a 7-Way blade style when needed. You can use # PK12-724. If you want to go ahead and switch from the 7-Way round to the blade style I recommend a multi-tow connector, # HM48470, which has a 7-Way blade style, a 5-Way flat, and 4-Way flat.

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...

  • Agricultural Type 7-Way Vehicle Socket for Trailers Using Round-Pin 7-Way Plugs
  • 7-way trailer connectors can be wired in several ways and heavy-duty commercial/agricultural round-pin 7-way wiring can be different too. Please refer to the linked image to see the different vehicle-side connectors and their common wiring configurations.
