I have been very happy with products I have purchased from etrailer. On my last purchase the one of the trailer end connectors was missing the locking retainer screw. Otherwise i have been a very happy customer!

A similar trailer light connector was installed on my motorcycle cargo trailer when I purchased it way back in 2003. When I purchased my new Gold Wing in 2019, I wanted to use the same type of connector. Since I had to add a new female connector to the bike, I decided to renew the male connector on the trailer. I especially like this connector because it always stays secure when connected. I also wanted the connections to be out of sight when not in use. I have pulled my trailer with this new connection for over 2,500 miles and it has performed great.

This Pollak system is just the right size for the hitch on my bike. It makes a clean, sturdy, and secure connection.

Mounted Pollak sockets to left saddle bag of 2018 Can Am Spyder RT for removal of "pigtail" extension to CSC trailer when not in use. This will eliminate any possible damage to hook up wiring and gives much "cleaner" look to hitch installation. I looked everywhere for these sockets, online & three auto parts for what I wanted and only etrailer.com had them and also the lowest price. Could not ask for more, arrived in 3 days, customer service follow up and answered my email technical question within 24 hours. Bookmark them and use on all your trailer needs. I have 4 trailers and do my own work.

This very hard to find item is of excellent quality and offers a very snug fit to it's male mate. etrailer had both the male and female items in stock, thereby providing super fast shipment at a very decent price. Prior to etrailer, no other parts provider even provided pictures of this item in their catalog. This item will be used to connect the electrical system of my Bushtec trailer to the mating connector mounted on my 2010 Honda Goldwing. Thank you etrailer!!

Much better than expected as the finish on the connector is completely free of rust, discoloration, or other imperfections associated with open road use items.. Of course the connector is mounted is a area that is subjected to water, rocks, dust and dirt, however I have not had any problems visually or electrically since installation. Mating of the connectors are still snug with perfectly clean electrical contacts.

by: Jerry C. 08/15/2017

Since I'm using this on a motorcycle I was looking for something that was fairly compact. This connector fit my needs but because it was pretty small it made installing the wires into the side of the pins a bit trying at times. I finally got around this by removing the crimping screws, running the wires straight in and soldering them in place. This worked very well and I feel a bit better about the connection.
However that being said, there's nothing wrong with the screw terminals at all. It's all just a bit small for big hands.

After pulling the trailer behind the motorcycle for several thousand miles I have no complaints. The fit and finish remains like new. Ive had issues with my connection. If I have need for a matching plug or connector Id reorder these in a heartbeat.

by: Chris 08/18/2016

Not much to write about, very simple and basic piece.
But, that's not the story here. etrailer.com is the real story, great site, very well laid out, for people like me. I took some time and looked at everything that I could see on this site. Lots of products sold at prices that just cant be beat. Super fast shipping. I think I got an email the next day my order had shipped. I will be back and will let all my people know all about etailer

by: David 09/22/2019

I like the look, and really easy to install, just make sure you do not strip much off the wire so you can put it through the hole under the screw, so as to not have any extra wire sticking out because they are really close.

Working great, converted 4-pin flat to 5-oin round as I wanted to add a power wire to trailer. This did the job!

by: Charles 04/28/2016

I've had the receptacle and plug version of this installed between a homemade truckbed trailer and my older toyota truck for several years and it works great, good connection, and easy to install. I went with the 5 conductors as all I needed were left/right signals, brake and running lights. I drive offroad a lot with the trailer without problems. I just received my second order, for an additional trailer, and the plug is really tight, thanks to the conductors being slightly too spread. I'll have to pinch the pins a bit to loosen the fit - easy enough. Otherwise it'd be 5 stars

by: Gary 07/27/2019

Wanted to use this plug as the bike and trailer both had them. This was to replace damaged trailer plug. One tube inside the plug was stripped the first time I tried it. The "mechanics" of the plug dictate that only a short bit of wire goes into the tube, to be held in place by a tiny screw. And one was stripped to begin with. I ended up lopping the plug off and going with the 5 pin flat plug. I wouldn't bother trying this plug if a flat connector would work in your application.

It was difficult to wire. The design with the screws on top cause the wires come out the side of the connection putting them under lots of stress. I had three wires break on me and had to start over 3 times before I was able to get it together completely with out breaking. I just hope they dont break in the future and my light quite working

With the help of Crystal I ordered this connector and a matching wiring harness for my motorcycle and trailer. I was unsure if these were the correct parts, but Crystal was able to locate the exact ones and ship them the same day.
I was very pleased with the fast service and knowledgeable staff. Even with standard shipping, my order arrived 4 days sooner than was projected.

To say I'm happy with etrailer is an understatement. They are great.

How To Wire a Harley Ultra Classic with a 5-Pole Round and a Trailer with a 4 Pole Flat
I am guessing that you have a connector similar to the 5-Pole round like part # PK11502. If this is the case, you have two options. You can either remove the 5-Pole round from your Harley and put a 4-Pole flat in place, or you can cut the connector of your trailer and use a 5-Pole connector for the trailer. I imagine the 5-Pole on the bike is mounted pretty well, so I would suggest replacing the trailer connector with a 5-Pole using part # PK11501. Using a circuit tester, like part # 3808,...

How to Connect a Surge Brake Actuator to Activate the Reverse Lockout Function
There are 2 wires that are coming out of the actuator in the Titan Disc Brake Kit # T4843300. You will want to connect one to the 5-Pole connector on your trailer and ground the other one using a Ring Terminal # DW05737-1; it doesn't matter which wire is used for which purpose. If you only have a 4-Pole connector on your trailer then I recommend using the Hopkins Endurance 5-Way Flat Trailer Connector # HM47910 instead. You will want to cut off your current 4-Pole and use Butt Connectors...

When Wiring a Motorcycle 5 Pin Round Trailer Plug What is the Standard Wiring Diagram
The Pollak 5-Pole, Round Pin Trailer Wiring Sockets, item # PK11502, and # PK11501, do not have a standardized wiring configuration. I normally direct my customers to the 6-way wiring configuration, eliminating the middle pin. Start by wiring the top most connector inside the vehicle end # PK11502, as with the taillight circuit (12 o-clock). Then looking inside the connector, where the wires are attached, going clockwise the next terminal (1 o-clock) position can be wired as brake output,...

If it was wired correctly the 5-pin should be have the 12 o'clock pin for the tail lights (brown wire) the 2 o'clock pin is the aux circuit (red), the 5 o'clock pin is the right turn/brakes (green) , the 7 o'clock pin is the left...

Pin Functions of Pollak 5-Pole Round Pin Trailer Wiring Connector

5 Pin Round to 4 Pole Flat Trailer Connector Adapter for Motorcycle Pulling a Trailer
Although we don't offer an adapter, you could construct one very easily. What does the 5th circuit from the 5 pin round connector on the bike power? I'm assuming that the circuits are ground, right turn, left turn, running lamps and brake lamps. Since the trailer you're wanting to tow has a 4 way flat trailer connector, presumably with a combined brake/turn signal taillight system, you'll need a taillight converter such as part # C56175. You'd wire the inputs from the converter to a 5...

How to Power an Electric Winch on a Trailer Pulled By a 2017 Subaru Forester
You do have a few options to get an electric winch, like the Dutton-Lainson StrongArm # TW4015, working, but the 4 Flat will not be able to do so alone. The first will be to add a battery to the trailer. This will usually be my suggestion, but as you do not have brakes on the trailer and it is for a boat trailer, it will not be the best way to go. What I suggest doing is upping your 4 Flat to a 5 Round, both on the trailer and vehicle. The Pollak 5-Pole # PK11502 for the vehicle side,...

Adapting 5 Pin Round Connector on Harley-Davidson to 4-Pole Flat Trailer Connector
The extra wire on your 5 pin H/D plug will serve one of two purposes. It is either the brake light signal or a constant 12-volt power feed to the trailer. You can easily determine which case you are dealing with by using a circuit tester like part # 40376 on the plug. Activate the turn signals, running lights and brakes to determine which pin carries which circuit. If the extra pin carries a constant 12-volts, and your trailer does not require any power supply, you could simply construct...

Adapting 5-Way Round to 4-Way Flat for a Motorcycle
The 5-Way on your Harley might actually have separate circuits each for brake lights, left turn signal, and right turn signal. A 4-Way will have the brake lights and turn signals on the same circuits. To tow a trailer that has combined wiring with a motorcycle that has separate wiring I recommend converting the Harley connector to match the other bike and the trailer. All you will need is a converter, # 119178. On the input side you will connect the wires from the bike's 5-Way. The red...

Hello Denns, I can definitely point you in the right direction for a wiring harness for your Harley Touring.

What is the Amperage Rating for Pollak 5-Pole, Round Pin Trailer Wiring Connector # PK11501
In terms of handling up to a 30 amp power draw the Pollak 5-Pole, Round Pin Trailer Wiring Connector # PK11501 can handle 15 amps. Thirty amps would be too much for it. That is why I would go with a 6-Way, # PK11604. As far as environmental conditions considering that I assume this will be on some sort of watercraft the outer shell is chrome plated and die-cast zinc so it does have decent protection against corrosion. After running wires to the plug and closing it up make sure to wrap...
