PURCHASED FOR REPLACEMENT OF 2003 CHEV. SUBURBAN OEM CORRODED PIGTAIL. FIT WAS OK BUT WIRING COLOR WAS DIFFERENT ON SOME WIRES. JUST MATCH WIRE LOCATION TO OLD PIGTAIL EVERYTHING WORKED OK



by:

Great item at a Great price and as always fast and secure shipping when ever I order from etrailer.com
George at etrailer is on top of every order and does an excellent job with communication and delivery.
Thank You, George & etrailer!



by:

etrailer Customer Service exceeds expectations... they have assisted in advising product uniformity and conformity..
The acquisition of the PK11998 will enable the unit to be returned to a state comparable to its original manufacturers designation.
Looking forward to an expeditious installation

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.



by:

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



by:

PerfectI resently purchased a new 4x4 and the truck game without a tow hitch ,so I bought one from the dealer and it came without the trailer plug so when I asked them how long do I have to wait for one they told me it was on a nationwide backlog so I went online looking at a few web sites but didn't see what I liked .I went crazy searching for this product until I log on to yours. I found everthing I needed and your prices where better than other venders ,And your shipping was on the money and didn't have to wait long . I would recomment your website to all my friends.



by:

Unless I misread the item description, this was supposed to be ford specific for my year and model. That wasn't the case. After matching different colored wires together, works perfect!

Thanks so much for your review, Rhett. This product is a universal fit. We recommend testing for function to match up your wiring before connecting. Here is the wiring configuration: Red - Left Turn and Stop, White - Ground, Blue - Electric Brakes, Green - Right Turn and Stop, Black - Battery, Brown - Running Lamps, Yellow - Backup Lamps

Decent quality. Functions as designed.



by:

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.

by:

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.



by:

BOUGHT A HITCH,ELEC BRAKE SYSTEM,WIRING,AND RUNNING BOARDS EVERYTHING SHIPPED FAST WORKS AND LOOKS GREAT CUST SERVICE WAS A BIG HELP ON THE WIRING SYSTEM GOT IT DONE



by:

Pigtail worked as expected with mating rv 7 blade socket. Easy for replacement of existing parts.



by:

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.

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



by:

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".



by:

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 ) .



by:

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



by:

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.



by:

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!



by:

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.



by:

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.



by:

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.



by:

I received everything in short order.
The
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.



by:

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



by:

Great product! Once installed the plug looks like it came from the factory that way. The instructional video made installation easy and the trailer lights work as they should.
The kit only came with 6 but butt crimp connectors, but 7 are needed. I had some of the smaller red connectors and ended up using 5 of them, the yellow clips that are included are a little large for some of the wires. If I ever have to do this again I would buy the heat shrink connectors.

  • Installing a 7-Way Trailer Connector on a 2013 Ford E-250 Van
    I checked with Tow Ready about 7-Way connector # 118261 and it is not a confirmed fit for the 2013 Ford E-250 van. Since there are no other options and since you have some factory wiring already, I recommend using 4 and 7-Way connector # HM40975 with harness # PK11998. You will need to test the wiring on the vehicle end with a circuit tester such as # PTW2993 to determine the functions. Then you can install the harness accordingly: Red - Left Turn and Stop White - Ground Blue - Electric...

  • OEM Replacement Trailer Connector and Wiring Harness for a 2002 Chevy Silverado 2500HD
    The OEM replacement 7-way trailer connector for the 2002 Chevrolet Silverado 2500HD is the Pollak Twist-In, 7-Pole Trailer Connector, # PK11916. If you also need the wiring harness with the round connector, then you will want the Pollak Pigtail Wiring Harness, # PK11998. Unfortunately, this is not a simple plug-in style harness. You will have to splice this harness into the factory tow package wires at the back of the truck. I have attached an installation video of this harness on a 2002...

    You can use the Pollak 7- and 4-Pole Trailer Connector Socket, item # HM40975, if you are replacing an existing 7-way connector on the rear of your 2004 Chevy Pickup. If you need to install the 7-Way connector for the first time the factory connection point is going to be on the left side of the vehicle above the spare tire. If there is a plug on the end of the wiring harness located above the spare tire, it will simply plug into the rear of the HM40975. If the harness ends in bare wires,...

  • Does Custer 7-Way Round to 7-Way Blade Adapter Have Signal Converter in It
    Hey Shawn, this is a great question but no the Custer 7-way round to 7-way blade adapter does not have a converter in it so that the separate signal circuits are combined. Basically this adapter is designed to just convert the styles of 7-way but not actually go from the semi truck style to RV style of wiring. To convert the signals you would need an converter like the part # RM-732 which you could splice into this adapter if you wanted. Sometimes in situations like this you can wire...

    Hey Don. I have a solution for you, but that part is not available anywhere as far as I can tell. The only custom fit part our vendors offer as replacement is the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C55316 which is a 4 way flat that connects to your factory connectors. Technically you could do that, then install the # ETBC7 which converts it to a 7 way round like you're wanting. That would be a lot of work if just the 7 way connector is damaged,...

  • How to Release the Locking Tab on the 4' Wiring Harness for Pollak Replacement 7-Pole RV Socket?
    Hey Gordon, welcome back. There's no specific amount of pressure mentioned in the installation instructions or the manufacturer's website to release the tab on the 4' Pigtail Wiring Harness item # PK11998.

The Hopkins Endurance Multi-Tow 7-, 5- and 4-Way Flat Trailer Connector, # HM48470, can be used as well but it is a hardwire connector meaning you would have to attach existing wires from the truck to the connector according to the wiring diagram I have linked for you.

    You do have the option to utilize the air brakes on your 2023 Freightliner Cascadia to control electric trailer brakes using the Hayes Air Actuated Trailer Brake Controller, part # HA100400C. However, we mostly recommend just using an electric brake controller since they tie into the stop light switch of the tow vehicle, making it irrelevant what kind of brakes it has.

  • Adding a Connector on a 2004 Chevy Express to Plug In Wiring Harness # 41155
    You could wire in harness # PK11998 to those factory wires on your 2004 Chevy Express. If you are only needing a 4-Way connector such as # 41155 then you would not use the blue, black, or yellow wires from PK11998 and can tape them up and tuck them out of the way. The wires on your van will need to be tested with a circuit tester such as # ALL640595 or a meter if you have one.

If your 2016 Chevrolet Express 3500 van had a factory 7-way and it needs to be replaced you can wire in a new one with a harness like # PK11998 and then connect it to a 7-way connector like # A10-7072VP or # HM40975.

In my experience, I've had fewer issues with 7-way plug fitting loosely with Pollak brand 7-ways and Pollak is generally the "go-to" brand for most OEM truck setups.  The snag is there isn't a 4-way and 7-way Pollak branded trailer connector currently, but I have some good news. The Hopkins 7 and 4-Pole Trailer Connector, # HM40975, is actually made by Pollak, but sold by Hopkins. This is the same plug I have on my Silverado...

  • 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.

    The clip that you are referring to that holds the 7-way plug to the socket is typically found on the connector which is why the # HM40940 does not come with it. I wish we sold that piece by itself but only way to get it is to go with a new harness like part # PK11998 and you'd be set. I like where you mounted the 7-way too. A lot of factory 7-ways install in similar places which helps prevent accidental damage like the scenarios you described.
