Exactly what I needed and It's a great fit



by:

Very Nice Rugged piece. Thanks much!



by:

Shipping faster than expected. Price very good. Great customer service. Good follow up after sale with installation videos.

This works well. I used it for a couple of years and never had a problem.

I made some changes that required a 7 pin connector and removed this 6 pin for possible use later on.



by:

these are just what need, I just got them in the mail about 30 min ago, could not find both parts at local farm store. these look like what I used when I was younger, they worked great then so should be good now. I thought I had a problem, but it was just me. Steve

used to replace pollak trailer hookup that lasted over 25 years



by:

I got exactly what I ordered, two replacement cable plugs for my tow bar from car to tow vehicle. Package included easy to follow instructions for wiring connections. The cable package from the tow bar company is pretty pricey but these plugs and the existing cable to repair cost around $10.00. I will probably order two more to have as spares.

Have no issues since the connector plugs replaced. Very satisfied.

No problems. Working as designed.

Great product just what I need thank



by:

Great price.



by:

Decided to make a spare pushbutton controller for my dump trailer so I wanted a good 6-pin connector that matched what I had. This was exactly what I needed. Good quality. Quick delivery. Good price. Had one hiccup with my credit card, and CSR's contacted me asap and got it all straightened out in no time. Would definitely order from etrailer again.



by:

I replaced the connector ends on the cable that hooks from my motor home to my tow vehicle.
The PK11604 are better made product than the original connectors. A machine screw is used to hold the
Receptial in place as compared to the original which had a flush head wood screw. The terminal hold down screws are stronger and easy to work with when installing the wires.





by:

Purchased some new LED lights for trailer. eTrailer has good prices and a good selection. Shipping was a bit slow but that may be be eTrailer's fault, we all know how the postal service works...or doesn't.

No reservations about re-ordering from this company, I like that George followed up with me afterward to make sure I'm satisfied.

Order with confidence!



by:

Works great, what I needed for the connection for my DC fuel pump to my fuel tank I carry in the bed of my truck. I have been a customer for a couple of years now and will continue to be as you always have everything I need then ship it out in a very timely matter.



by:

I ordered replacement side markers and was pleased to find the bulbs came sealed to the lense. The ones they replaced had twist in bulbs that would work out of the back of the lense. Better than expected product and prompt shipping. Thanks, Jim D.



by:

Good replacement for the original.



by:

exactly what I needed works perfect



by:

This connector was used to replace a similar no name Chinese knock-off that had corroded badly. Also, I no longer keep the trailer cable connected and left in the elements. Easy to disconnect both ends and store separately.



by:

This item and the receiver were exactly what I was searching for. I have a motorcycle trike, with a matching motorcycle tow trailer. That is what these items were ordered for. Very happy with purchase and shipping.



by:

Was impressed with the websites videos showing how to remove, replace and wire these fittings. When the fitting arrived the procedures were as easy as demonstrated. Did note however that the old fittings showed silicone sealant around the wire connection points and don't recall that being part of the instructions, but seemingly a good idea



by:

All parts delivered promptly and packaged securely. I will be mounting the 6-pin plastic wiring socket into the underside of my Honda Goldwing trunk and connecting the 6-pin connector to my Uni-Go single-wheel trailer.



by:

I received the plug/receptacle for my 2002 Chevy van promptly and it was the right fit. The videos provided on the site were very helpful in wiring the plug correctly. All-n-all, a great experience and I would recommend E-Trailer to anyone.



by:

I really appreciated the detail etrailer.com provided with each of their products. I was confident of what I was buying and that it would do what I needed to do. I will definitely be buying from them again in the future. Shipping was fair priced and very quick! Thanks a bunch, etrailer.com!! - Ryan



by:

The Pollak quality is always great! I use this style plug for my trailers. They last longer than the cheap rubber plugs and are easy to maintain.

  • How to Wire 4 Trailer Wires Into the Pollak 6-Pole Trailer Connector
    Typically, the wire colors are brown for running lights, green for right turn and brake lights, and yellow for left turn and brake lights. White is ground. To confirm this on a trailer you can trace the wires back to see where they terminate or take a separate 12 volt battery and use it to power each wire to see what lights up. To wire up the 6-Way # PK11604 with the 4 wires if looking at the back of the 6-Way where the wires attach running lights will be in the 12 oclock position, ground...

  • Troubleshooting Horse Trailer Brakes that Lock Up when Trailer Wiring is Connected
    What you need to do is swap the center pin and the pin in the 2:00 position of your horse trailer's 6-way and the problem will go away. The reason this is happening is that for some reason there are two different ways people wire up 6-ways and the only difference is the brake output and 12 volt accessory circuit pins are swapped. If you cut the two wires and then splice to the other pin it will work just fine.

  • How to Determine Functions of Trailer 6-Way Wiring if All Wire Colors are Same
    You'll have to determine the functions of the wires and then wire them by function to the 6-way diagram I attached. Determining the functions of the wires can be done by you tracing the wires back to see where the terminate or you can put 12 volts on each wire to see what activates and go from there. You might use a piece of tape plus a marker to label each of the wires for the future.

  • Troubleshooting Trailer Taillights that Stay On When Not Connected to Battery or Vehicle
    So the trailer is not connected to your tow vehicle and there isn't a battery on the trailer but somehow the lights are staying on all the time? Does the trailer have a breakaway battery at least? Most likely it does and that would be about the only thing that could power the taillights of the trailer. Best option would be to go over the wiring of the battery and see if there's anything obvious that would short it out to the taillights like cut or exposed wire caused by the squirrel.

  • Which Wire is the Ground Wire on Sundowner Horse Trailer 6-Way
    Between those two color choices the black one would most likely be the ground wire. However, if you hook it up with the black as the ground and it does not work I would recommend trying the red wire. Also, you should trace both of these wires back on the trailer to see where they terminate. The ground wire should be connected to the frame of your trailer. Whichever one connects to the frame is the ground. The ground wire should be wired to the 12 o clock position terminal on the Pollak...

  • Troubleshooting Trailer Brakes that Lock Up When Using 6-Way Adapter
    Your problem is related to the 7 to 6-way wiring adapter. The issue is that there are two ways that a 6-way is typically wired and the only difference is that the 12 volt accessory circuit and the brake output circuit are swapped. Anytime we see trailer brakes immediately locking up when connected and there's a 6-way involved this is the issue. What you need to do is swap the two circuits on the 6-way adapter or the 6-way connector and you'll be good.

    I have attached a photo that shows how the Pollak 6-Pole Round Pin Trailer Wiring Connector part # PK11604 will need to be wired. In order to make sure that you are installing the correct wires into the correct pins you will want to use a separate battery and power each of the lights on the trailer's wiring harness while checking for continuity with a circuit tester like part # ALL640595. This will also allow you to see if power is not going through the wires that lead to the taillights....

  • Troubleshooting Trailer Wiring Where Left Blinker Barely Lights Up
    Most likely it has a weak ground for that circuit. Try checking and improving the ground of that light assembly and most likely it will start to work like you need it to. A lot of times they ground through their hardware so make sure it's connected to a clean metal surface. Or you can run a jumper wire from ground to the main ground of the trailer wiring. I attached a help article that covers trailer wiring troubleshooting as well.

  • Reading 12-Volts on 6-way Connector of Kaufman Tilt Bed Trailer
    Do you mean that you're using a circuit tester on your 6-way connector on the trailer (not the truck) and you're reading 12 volts on one of the pins? The only way that would happen would be if you had a battery mounted on the trailer. Typically, the battery is connected to the 12-volt supply circuit off the 6-way to receive a maintenance charge.

The wire that is attached to the trailer frame is the ground and should be attached to the 10 o'clock position of the Pollak 6-Pole, Round Pin, Trailer Wiring Connector, part # PK11604.

  • Troubleshooting Trailer Brakes that Lock Up When Connected to Trailer Wiring
    This is a fairly common problem for trailer setups that use 6-way connectors like the # PK11604 that you referenced. The issue is that there is two accepted ways the connector can be wired up. The only difference between the two setup is that the brake output circuit and the 12 volt accessory circuits are swapped. It sounds like your vehicle is wired one way and the trailer is wired the other way. What you will need to do is swap the two circuits on either the trailer or the truck. It...

  • Horse Trailer Brakes Lock Up When Connected to 1999 Ford F-250
    It sounds like either the trailer side connector is not pinned to match the vehicle side connector or there is a short circuit (possibly due to corrosion on the pin or inside the trailer connectors) causing the brakes on the trailer to lock up. The easiest thing to check first is for dirt/corrosion on the pins and inside each of the trailer connectors. Then you can make sure that the trailer side connector is wired up to work properly with the vehicle side connector. I have included a...

    Sounds like your trailer wiring does not have a ground circuit for it's connector. The easy solution for that is to run a wire from the ground pin of the connector to the trailer's frame. Your trailer electronics should work a little better now as previous to this it was grounding through the ball mount.

    I have included a picture for the trailer 7-way connection and the typical wire colors used and their location. As the wire colors are not standard for every trailer you will want to confirm what each wire does. The easiest way is to use a 12 volt battery to isolate what each wire does on the trailer. If you do not have the capability to do this you can also use trial and error. The wires are most likely as follows. Red- Left Turn/Brake Light Brown- Right Turn/Brake Light Yellow- Reverse...

Which leaves us with the two black wires. There are a couple options for determining what the black wires are for.

Or, you could trace the wires back to see where they terminate. One...

  • Troubleshooting Trailer Blinker that Locks Up Trailer Brakes In Sync with Circuit Flashing
    What is happening is that the left blinker circuit is shorting out on the brake output circuit which is causing the brakes to apply in sync with the blinkers. I imagine the brakes are applying very harshly now too as the brake assemblies are getting a full 12 volts when the brake lights come on. Sounds like you have some wiring issues on the trailer that need to be addressed. Best bet is to go over all of the wiring looking for any cut or exposed wire and fix as necessary.

    You have discovered the "dirty little secret" of trailer wiring: wire colors are not a consistent and reliable way to figure out what each one does!

It is easiest to use your vehicle battery (or a well-charged spare battery) along with a set of jumper cables and two lengths of wire. This makes it simple to apply +12V power to each circuit on the trailer (one...
