After I received this item, it just sat on the shelf until I could find the time to install. I just review this and I find the 7-pin plug is missing. The mounting flange and wiring harness is there, but not the 7-pin plug.

Well you need the 7-pin plug! Let me get you over to our customer service department for them to get you this missing part.

1973 Chevrolet C/K Series Pickup

Installation was easy, good instructions. used this in conjunction with a Prodigy brake controller on a 1973 Chevy K20 square body pickup, replacing my original. wired using crimp on connectors, fast easy, clean. Re taped all connectors and loom. Used silicone on the back of the to seal off moisture.

Craig N.


After a year of constant use the everything works perfect. So nice to hook up, plug in and go. Perfect.


This was a perfect replacement for an old worn out 7-pole connector on my motorhome. This unit has a heavy guage wiring harness with standard color coding for each wire. The socket has a sturdy spring loaded cover that should keep out water a dirt. The instruction sheet includes a wiring diagram. I like that the connector socket can be easily removed from the wiring harness if it ever needs replacement.

Chevrolet Silverado

Although parts have only been installed less than a week this was a direct replacement for my Chevy Silverado 1500hd harness and outlet. I relocated from the side of the receiver to the bumper. Everything is provided in the kit. I used different hardware due to installing through bumper and different butt connections with heat shrink tubing because this was one of my reasons for replacing, the other being corrosion in harness to socket.


Fast we'll packed shipping no damage.lights work great on my featherlite trailer.


Appears to be high quality connector! I like the fact that it comes apart so you can mock it up on your truck's bumper, frame, etc. and the connector is well made and even has a seal inside making it watertight. Glad i bought it! Istall appears to be very easy and the length is long enough to where you can have options during install.

2001 Chevrolet Silverado

The Curt hitch was delivered on time and in good condition.I had prepped the threaded holes in the frame earlier,which made install easy.Took all of 15 minutes ! This is my second time using Curt hitches,the last one on our 2013 Honda CRV.Great installation video and instructions. Would purchase again . Thanks!!!!

Jim L.




Received precisely what I expected I was ordering. Looking forward to getting this installed.

2003 GMC Sierra

great parts / fast service

2005 Isuzu N-Series

All the hardware is included to install.

2007 Ford F-150

his is the product if you do not have the trailer package on your vehicle. The 07 F150 I bought does not have the trailer towing package so I could not buy the plug and play version of this. The wire length is good so that you can easily locate the socket and still reach the vehicle's wiring harness. The instructions were good but I had trouble finding the correct lead for +battery to hook up to. Great price and delivery from etrailer as always.


I purchased this as a replacement for an identical wire harness already installed on my vehicle. Old harness was occassionally losing taillight/running lamps. Note that the new harness is the same make and model as old harness yet 2 wires are of different color (i.e. old + wire was red, new + wire is black) trace your wires carefully if performing a replacement.

Harness was received in just a few days and included all needed components for installation. I soldered and used heat shrink tubing on connections. The inclusion of waterproof butt connectors would be a good addition to this package instead of the included standard butt connectors.

2000 Fleetwood Bounder Motorhome


2000 Chevrolet Silverado

Replaced the old 6pin that was on my 2000 Chevy Silverado. The installation video was very help and recommend watching it.


This has worked great on my vehicle. I put a 30-Lb magnet on bracket and that gives me the flexibility to mover the connector when in use.



Still working great. I like that it is hidden behind my bumper fascia until needed.


Great product. Very Well made and more than enough wiring to complete the job.
2000 GMC pickup and the wiring had been cobbled up back to the trailer receptacle.
Only took about 30 minutes to complete the job. The instructions regarding matching up the wiring from the truck to the new wiring harness were concise and easy to follow.


I want to thank Molly for all the help for pk11898 I have not yet installed this harness planning to do so to day weather here in McKeesport has not been that good. Again thank you Molly for all your help you are a asset to the company.

Cresson A.


Works great

2008 Ford F-350, 450, and 550 Cab and Chassis

Product was just what I was looking for.
I would like to say something more about the customer service if I may.
I received a call from Molly with etrailer letting me know there was a slight shipping delay of one of my items in my order so if I did need it right away I could make necessary changes. I would like to personally thank Molly and the team at etrailer for going that extra mile!


This connector socket and wiring harness were exactly what my husband needed to get his truck and trailer working together. Thanks for providing this complete solution!

1999 GMC Sierra

Worked great. Spliced the ends of the connector wires into the proper wires above the spare and mounted the unit on the bumper.
Mfg could have included some silicon dielectric compound for the electrical contacts.


A very good harness and it is working fine a year after I installed it, however, the mounting screws are rusting so the reason it did not get a five-star review is because in my opinion the mounting screws should’ve been stainless steel

2001 Ford F-150

As always, great product, good price, and very fast delivery! I appreciate being instructed to verify my trucks wiring, because, although I thought my 7 pin was original it turned out that my truck was only wired with 6 wires. My truck had no red wire and the yellow was used in place of it.i hooked the new adapter's red wire to my feed yellow, abandoned the new yellow wire, and I'm good too good!


Working great. Initial install required running at lest one wire from the distribution panel at the front of the PU to the back because Pick up was not originally wired for a 7 pole plug. Been doing its intended job.

2001 Chevrolet Silverado

Arrived as advertised....perfect replacement on truck.

Thank you!

  • Mounting Bracket Dimensions for the Pollak 7-Way kit part # PK11898
    I attached a picture that shows all of the dimensions of the mounting bracket that comes with the Pollak 7-Way kit part # PK11898. We have found that nearly all 7-ways use the same dimensions so this SHOULD work but you would still want to verify.

    Your best option would be to cut off the 4-way round and wire in a 7-way blade connector like the part # PK11898 instead as there isn't an adapter for you situation.

  • How Do I Separate the Trailer Connector Socket from the Mounting Bracket After Performing a Test Fit
    In order to separate the Pollak Trailer Connector Socket and Mounting Bracket, # PK11898, you will need to slide the grey clip toward the wiring. This clip can also be removed if needed. Then you will need to press down on the black clip, which was in the center of the grey clip, while pulling on the mounting bracket. I am attaching a quick video to demonstrate.

  • Can 9-Way Trailer Wiring on Vehicle be Replaced with 7-Way
    It would be a matter of removing the wiring from your current 9-way and running it to the new 7-way. We have the kit part # PK11898 which you could butt connect the wiring you have to. But you do need to determine why you have a 9-way currently. Do you have extra circuits beyond standard trailer wiring, or does your trailer wiring have separate stop light circuits from the turn circuits?

  • Does 4-Way Need to be Installed Before 7-Way of 2000 Ford F-150
    If you wanted to run the wiring straight to a 7-way that's underneath the rear of the 2000 Ford F-150 like with the Pollak 7-way part # PK11898 and you'd be set. There's no need to install a 4-way first. I attached a picture that shows where the wiring is at the rear of your truck.

  • Is it Okay to Swap Pins for Auxiliary and Brake Controller for a 7-Way Connector on a 1997 Ram
    When wiring your Pollak 7-Way like part # PK11898 it is really important to connect your functions like what you can see in the attached photo instead of going by colors or slight differences in wire sizing. The exception to this is if your trailer is wired differently then it would be advisable to wire the connector on your 1997 Ram to match your trailer. Otherwise every time you connect to a trailer you are going to experience problems as the functions from your pickup won't match those...

The middle right pin should be hot at all times, the bottom right pin should go hot when the brakes are pressed the top right pin is the trailer brake feed circuit and the bottom left pin will be the ground wire.
