New wiring harness and receptable work great. Installed in the rear of my truck bed for connecting my 5th wheel much easier than running the RV cable over the tailgate to the 7-pin connector by receiver hitch. Thanks...

The colors on the wiring do not match the truck.

When it comes to wiring on a vehicle, you will have to contact the dealership to get that information. As for the wiring on the end of the harness, we do have a diagram in the link below:
Katrina B - 11/01/2022


I received everything in short order.
instructions from the website gave great detail.

The only thing I would add would be to measure the distance between the

tabs on the original hitch and make the same on the new one by

bending/taping them.


Used this product in conjunction with pollak #pk11893 to upgrade my 95' ford E-350 wireing under the rear bumper to more readily available standard parts. I have had a few orders over the years from etrailer, always a pleasure to deal with.


The Pigtail assembly that I received was wired incorrectly. Normal seven pin color coding was not followed. The Yellow wire (normally left turn/stop light), was wired into the backup light center pin, the red wire (normally +12 volt supply), was wired into the left turn/stop pin, and the black wire (normally backup lights), was wired to the +12 volt supply pin. Good quality wire and correct gauge, probably just a supplier / quality control issue.

Theres more than one accepted wiring convention for a 7-way trailer connector, which is why we list the wire color code on the product description page on our website.

The pig tail was actually wired wrong to the plug. Found this out out after testing unit. Should have been a very easy install

The pigtail isnt wired wrong, it just uses a different color code. The color code it uses is: Red - Left Turn and Stop - 14 gauge White - Ground - 10 gauge Blue - Electric Brakes - 12 gauge Green - Right Turn and Stop - 14 gauge Black - Battery - 12 gauge Brown - Running Lamps - 14 gauge Yellow - Backup Lamps - 14 gauge

Product as advertised. High quality. quick delivery.


As always, the right product delivered on time. Turned out it was not what I needed, but the error was mine. I will put it in my handyman stash and it will eventually be used.


Great quality easy install


After checking the wiring harness 1 more time as Korren suggested, I found the bad connections. The new harness fixed the problem.

Good product and good support.


Looks to be quality.


Just received the wire pigtail today. Had ordered the 7 pin plug thinking I wouldn't need the pigtail. Save yourself some time and get them both. It's cheaper in the long run. Good product.

I completely rewired my trailer about a year ago using all of your wiring and lights. Everything works great. Thanks.
Tommy F - 04/13/2019


This harness plugs right into the factory 7 pin plug that comes with the factory hitch and works perfectly to replace a worn factory plug.My ground wire pin had become loose in the plug and had my trailer lights working intermittently .GM also sells a repair plug but it is over $100.00 and comes with the 7 pin plug and a four pin connector which I didn't need.Just be sure to connect one wire at a time as the color of some wires do not match.I started with the white wire and worked my way around the plug and it works perfect.Thanks for a good product at a great price!


This also fits the Pollack 11-916. The PK 11916 seems to be the twist lock version of the 4 bolt 11893. The 11916 came with the GM hitch that I installed on my Silverado.

Caution; once I pushed the PK11998 onto the PK11916, the internal locking tab engaged without using the external lock / unlock button. The only way to get the harness off was to force the two apart thus breaking the internal locking tab. That doesn't seem to be a problem because everything is a tight fit anyway. The locking tab seems to be overkill, kind of like "wearing suspenders with a belt".


I needed a 2nd, 7 blade trailer connector for my '15 Ford S.D. 350 Dually.
I wanted to keep the factory look, and this product matches perfectly. Wire harness & bracket were also purchased. ( due to a totally custom built Toy Hauler, more than 7 standard wires were needed for trailer ) .


The color code is all wrong with this harness. After I wired all the colors together, I tested my trailer lights and the left side didn't work. After researching on the etrailer site I come to find out this thing is not inline with the standard color code that every trailer under the sun uses. There should be a highlighted note saying that it's different from the normal color code or something. Had to rewire and heat shrink.


E-trailer has always been fast, responsive, and helpful on many of my orders. Used this to replace a broken truck side connector on my 2012 F250. It's exactly the same as the factory plug. The wire harness on the 2012 is over 300 from Ford on the late model 2011 and up F250. Instead you can cut and splice this connector. The wires are a different color but you can see the numbers on the factory and new connector and match them up. I did decide to solder and shrink wrap my wires but the kit comes with butt connectors. Good quality part no different then OEM and fits well on the existing 7pin putco connector.


I bought this because my 2011 Silverado factory 7 way connection was acting poorly. I had to cut off the wire harness end and splice this on, I used heat shrink solder connectors then replaced the seven way. Now the voltage to the trailers brakes is at max with no more intermittent issues, this looks well made


Bought 3 items--Trailer connector socket, mounting bracket and 4' pigtail. They were just what I needed. Did not know ID #'s and names till I got help. Then looked at video of how to wire the wires that weren't color matched . Not only was it simple and quick but less expensive than competitors. Shipped same day --- took 3days counting shipping day to arrive. Super customer service, price and shipping time.
Thank you Etrailer. Will buy again when I need your products and am already telling my friends.


Should work


soldered the wires to the factory wiring harness. Looks like it came from the factory. 2016 Chevy Colorado.


This was right part for my 2016 Colorado. Very good video on installation. I paired it with part #HM40975. Great hook-up. I installed Draw-Tite receiver (#75948). Everything work as advertised, but video for install of hitch wasn't accurate. But good enough to get the job done. After I was done with total install, I was very happy. Ready to pull my trailer anywhere.


Just what i needed to fix someones mistake! This allowed me to replace the factory end on my GMC truck i just bought. The only issue was the yellow wire on the pigtail is for the backup lights and not the left turn signal. I just checked everything with a test light as i went and all was good.


Wow...I can't believe it, it's everything said and better and it was easy as 1 2 3 to install. I never installed one of these brake controls before and it was easy. I did however have mechanical experience back ground but it is still easy for the do it yourselfer. Thanks.


Like everything about it, EXCEPT the wires are not standard colors. wired it up the first time without looking at the description online had to cut and rewire. So watch the color diagram- otherwise excellent

  • Does 4' Pigtail Wiring Harness PK11998 Fit 2012 Ram 3500
    Yes, the # PK11998 that you referenced will fit the 7-way connector you have at the bumper of your 2012 Ram 3500. Basically all 7-ways use the same style round connector at the rear of them and that is what this harness has.

  • Troubleshooting Prodigy Brake Controller with PL Error Code
    The PL code will be displayed when the Prodigy loses voltage on the black wire while either the brake pedal or the manual lever is being applied. This may be caused by a loose connection or I have also seen a faulty circuit breaker case this as well. The circuit breaker I referred to would be on the power wire of the controller. The black wire of the controller should run through a circuit breaker and then to the positive side of the vehicle battery. You might try bypassing the circuit...

  • Troubleshooting Vehicle Trailer Wiring Running Lights Circuit that Doesnt Function
    Most like there is a blown running light fuse on your 2000 Chevy Silverado 1500. If you check the fuse panel under the hood you should find a trailer running light fuse. You can also trace the running light circuit back from the connector to see if there are any breaks in the wire or anything else that could cause a short and fix as necessary.

  • Will Pigtail Wiring Harness # PK11998 Fit a 2013 Ford F-150 FX4
    Pigtail Wiring Harness # PK11998 plugs into the back of a 7-Way vehicle side connector. This style is called a US car connector which should be what is on the back of your trailer connector on your 2013 Ford F-150. That is the type of connection that I have seen on the 2013 F-150 so it would plug right in to the back of the vehicle connector.

  • Availability of Longer 7-Way Harness for Chevy Silverado for Aftermarket Bumper

  • Option to Make 7-Way Extension for Truck Installing Tommy Gate
    Best option we have would be to use the part # PK11998 as a 4 foot extension like you need. You'll have to cut off the round connector you have now behind the 7-way socket and wire this in place of it as we don't have a solution that plugs right in.

The pigtail would wire up according the description shown on its product page, which you can see by clicking the provided link.

Most of the tow package wiring can be found in a wiring harness above the spare tire. The yellow wire in the tow package harness connects to the red wire in the pigtail. The white ground on the tow package wire is connected to the white wire on the pigtail, the blue pigtail wire attaches to the...

You mention that you have a 2005 Silverado, the Twist-In Connector is compatible with the New Body Silverado, 2007-Present. You would want to go with the # PK11893.

  • Wire Connections for the Pollack OEM Replacement 7-Pole Trailer Connector # PK11893
    The Pollack Replacement OEM 7-Pole Trailer Connector, # PK11893, was designed to be an OEM replacement socket for Ford, Chevy, GMC and Nissan vehicles. This socket was designed to work with the OEM wiring harnesses. If you want to use this socket on your vehicle and you do not have an OEM trailer socket connector, then I recommend using the 4 ft Pigtail Wiring Harness, # PK11998. This wiring harness will plug into the rear of the Pollack 7-way socket and it provides 7 wires that you can...

  • Wiring Harness to Plug into the Back of a Pollak 7-Way Trailer Connector PA66GF30
    The Pollak # PK11998 wiring harness is the correct one that you would need. It plugs into the back of many different types of 7-Way trailer connectors so it isn't surprising that the one you have looks different than the ones we carry. As long as your connector has the round receptacle in the back to plug in a harness # PK11998 will work. I believe the one you have is the same as or similar to # PK11893.

  • Wire Gauge Recommended for a 7-Way Trailer Connector
    The 7-Way trailer connector # PK11893 does not take any wire directly. It is what is called a US car connector. There is a mating harness that plugs into the back of it that will either already be on the vehicle or you would use # PK11998 which uses a mix of 10 to 14 gauge wire. Going with larger gauge wire (10 is usually the largest you will see for trailer wiring harnesses and connectors) can lead to a level of resistance that will cause some functions not to work properly. Unless you...

You would be able to cut off the damaged harness and wire this is place of it and you would be ready to install the # PK11893.

  • The Pollak 7-Way Connector Doesn't Match The Wiring On My 2011 Chevy Silverado 1500
    The Pollak Replacement 7-Pole # PK11893 is intended as a factory replacement for a damaged OEM 7-Way, so it will utilize the standard snap in style design (pictured) found on Ford, Chevy, GMC and Nissan trucks and SUVs. With that said, I am not aware of any 7-Way connectors that use a twist lock style connection, so you may want to cut that side off and replace it with the 4' Pigtail Wiring Harness # PK11998. This uses the standard snap in style that the # PK11893 has and they will connect...
