Tow Ready Tow Package Replacement Vehicle Wiring Harness by Draw-Tite, Hidden Hitch and Reese

1999 Ford Ranger

Installation was very simple.
The item
was just as described. I have not hooked it up to the trailer yet. But It looks good so far.

2000 Ford Explorer

Becuase if this website it was easy to find what was needed for my truck to tow. Very detailed installs online. The best part was everything was bolt in and no drilling required along with plug and play wiring harness. Definitely will be another custom tee in the future!


I changed all the lights in my 98 Ford Ranger to LED and added a Tailgate light bar. The Hopkins inline adapter that I already had showed a cross talk problem with the LEDs but not bulbs. If you had the tail lights on and turned on a turn signal, the opposite side flashed dimly making it look like hazard lights were on. This adapter was a perfect straight wire fix that plugged directly into the existing trailer light pigtail to provide a 4 wire connection and it was priced cheaper than I could do it myself. Easy to install and tucked away neatly. Notice there is no dim right turn signal now when the left one is on. Thank you etrailer for having what I needed and the great customer service!

1998 Ford Explorer

Like the reciever the wiring harness arrived 2 days early and it was a plug and play item, perfect for my 1998 Explorer..

It took just a few minutes to remove the dust cap from the plug which was located behind the drivers side rear brake light under the Explorer and then just plug the harness in and route it in the best location you can find...


High quality products, does everything as advertised. Super easy to install and worked great. A little slow getting my order but with the pandemic that's to be expected

Harness still operating as it should, not a problem with it at all. Works as good as any factory wiring.

Fit perfectly

1997 Ford Explorer

I am truly amazed with Not only did I find the wiring harness for my '97 Ford Explorer but it arrived as scheduled and was easily installed within minutes. The support team was also fantastic in following-up on my order and offering technical support if required. I definitely recommend this site and the entire team and plan on starting my search with for future needs.

My etrailer product was easy to install and has worked flawlessly for one year. When I need trailering products I definitely will go to etrailer first!
J R - 11/25/2018


Everything was perfect and after a year still is. We have had no problems with this item at all. Thank you


It was the same part. And fit and work. Thanks so much. Michael

2000 Ford Explorer

I spoke to my mechanic (who failed to locate the round plug that your video shows) who said I might be paying hundreds of dollars and hours possibly, to splice wires and get it right for trailer lights. Then I watched your video, total time five minutes, went out to my 2000 Ford Explorer Sport, 3 minutes, saw the plug, ordered the part $12---then installed--3 minutes. Wow. Thank you. No splicing, no mess, no fuss. Just plug it in. I tested it with the boat trailer and horse trailer-everything works perfectly. Can't beat it.

Everything is still working perfectly. You have no idea what complicated baloney my mechanic, as well as store clerks at several Automotive stores, told me about what would have to happen to connect my horse trailer. And the money I needed to spend, in labor and in product. You solved that with very little money needed and five minutes to hook up. So, yes I am still very happy.

Wiring Harness was delivered on schedule. Was a "snap" to connect to existing wiring coupler--plenty long--and works perfectly. 100% content with this purchase, price, and ability now to light and signal utility trailers.

The product is fine no problems. Satisfied....

Received the wrong wiring harness from another site so I decided to try etrailer. They had the correct harness and I received it quickly. Site is easy to use. Overall a very good experience.

No problems or issues to report...

2000 Mercury Mountaineer

Harness came quickly and appears to be OEM harness as described. Original harness connection was behind the left tail lite. Capsule was removed (two screws at top of tail-lite). Connection was done and cable routed and positioned under bumper in less than 5 minutes. I presume the old harness had some corrosion as this did the trick. I did purchase a flexible cable protector to put around the harness wiring to prevent damage. It took me longer to write this review than it did to fix my problem.

Using some electrical contact grease, like part 11755, will help keep moisture out and drastically slow corrosion.

1998 Ford Explorer

Perfect fit for my 1998 Ford Explorer Eddie Bauer v8 AWD. Factory connector is easily accessed by removing the driver's side taillight housing. Connect fit was snug and secure.


easiest trailer wiring i've ever done. pulled off a dust plug, plugged in adapter, and down the road i went..

works great. have no problem with it. plug in and take off
bradley g - 03/04/2017


I wish I could tell you it works great but I can't :( I wasted my hard earned money as ALWAYS, something is wrong with the factory wiring in my truck so it don't get power to the plug. more stuff for the shelves in garage that I have sadly wasted money on by NO purpose of mine..

Thank you for your review. Although I am not sure which year make and model you have exactly the first thing that comes to mind is a blown fuse. Most trucks with factory wiring have corresponding fuses for 12V power. I recommend to check your owners manual for the location of the fuse and see if it needs to be replaced or added.

2001 Ford Explorer

The trailer light harness worked as advertised and installation was a breeze. The harness was very reasonably priced and the item arrived as promised. The one thing I truly liked about what '' did is that they had a video on how to install the harness. For me, it helped out tremendously to watch on how to install it and what to look out for. Credit to this company for providing this type of assistance. I will definitely buy from them again.


Perfect and available for my older vehicle when nobody else could locate it. Factory fit

1999 Ford Explorer

Wiring adapter was simple to install, plug and play on my 1999 Ford explorer. Hooked right to the factory wiring harness with a click and we were finished. Used the trailer twice since and no issues.

1999 Ford Explorer

got a reciever hitch for a 99 ford explorer and wiring adapter. everything needed except spanners/ wrenches was there . very clear simple instructions. fitted it this morning took 30 mins 6.30 to 7.00 before going to work . everything fitted and holes in frame were where the instructions said they would be. i have fitted many hitches and this was by far the easiest. wiring adapter plugged straight in. Full marks Etrailer I will be back for more stuff.

2000 Ford Explorer

It appears in spite of many sites selling this exact part, as if it fits a 2000 ford explorer xlt 4wd, it in fact did not. I noted immediately the two "bayonet" alignment pins were in the wrong place, relative to the ford under-vehicle tow port...and thinking it might yet fit I cut off both bayonets. I believe there is but one bayonet slot, on the ford plug port. Neither bayonets on the part I bought aligned with that. When the two not-aligned bayonetsw were removed form the purchased adapter, I was thus able to plug into the ford-supplied terminal --but, sadly, it did not work. I called to let your company know and indicated I desired no refund as I had modified the part, and if possible was there a correct fitment with another part number? The gentleman on the company end did his best and concluded other related parts would not fit. In the end I have gone to a universal kit from my local walmart. Oh well. The price shipped was very reasonable and I took a chance that did not pan out. Please (this said to the dealer of the no-fit part); go and check for yourself on a 2000 ford xlt, 4wd 4-door with a 4l cologne engine. It shall not fit. Life's all about choices and chances. Sometimes you win, sometimes no.

Ford Explorer

Plug and play. Ford made hooking up trailer lights for the Explorer easy. If you have this harness kit, just unhook the left rear taillight, pull it out, plug this into the connector that's on your truck's wiring, and you are done. Beginning to end, it takes about three minutes to wire your truck for trailer lights with this.

1998 Ford Explorer

We bought a utility trailer and needed a wiring harness to hook up the lights. Going thru your company we saved a good bit of money. The product arrived on time and worked perfectly. The trailer passed inspection with flying colors!!
We would recommend etrailer to anyone! Thank you!

  • How to Remove Dummy Wiring Harness Cap from 1998 Ford Eddie Bauer Explorer
    Thank you for the photo of your 1998 Eddie Bauer Explorer's trailer wiring harness cap. Between the age of the plastic material and the exposure to road grime (that might be trapped in the gaps, making cap removal as difficult as possible) I am not too surprised you're finding it tough to get the cap off. Add the fact that there appears to be no way to get a hand around it AND at the same time press the cap release (red arrow) and I can feel your pain. Here is my thinking. There probably...

  • Troubleshooting Taillight and Brake Light Circuits Not Active on Trailer Wiring
    Based on what you described it sounds like your trailer wiring has a weak ground and when you try to use the circuits that draw the most amperage the lights stop working. This is pretty common. What you can do is try improving the way the lights ground or run a jumper wire from the lights back to the main ground circuit of the trailer wiring and then the circuits should start working. I attached a help article on troubleshooting trailer wiring with more info for you to check out as well.

  • Troubleshooting Trailer Wiring of 1994 Ford Explorer Not Functioning
    Due to age of your Ford Explorer I was not able to pull up an online copy of your owners manual to find the fuse/relay locations for the trailer wiring. If you check yours and find the fuse box section it would be listed there. Also it's very possible your trailer wiring just has some corrosion on the pins which is causing the circuit to not be active. You can clean them with some sandpaper and that most likely will take care of the problem. I attached a help article on trailer wiring...

  • Tow Package Fuse Locations for a 1998 Ford Expedition

Position 16 is trailer battery charge circuit. Position 28 is brake controller relay. Aside from that you would want to check all towing related fuses using the diagram on the fuse box lid.

  • How Does the Tow Ready Wiring Harness part # 118241 Install on a Ford Explorer
    To install the trailer wiring harness part # 118241 on your 1995 Ford Explorer you would need to Locate the vehicle's factory tow harness connector behind the right side of the bumper.

  • Troubleshooting Trailer Blinkers that Flash Together and No Brake Lights
    If I am understanding you correctly it sounds like you had a trailer light assembly break and after that the brake lights stopped functioning and the blinkers now both flash at the same time. Most likely what happened is that when the assembly broke it tore some wiring and now you have shorts between some circuits. If you check the wiring of the assemblies and clean up any shorts this should fix the problem. I attached a help article on troubleshooting 4-way installs as well.

  • Not Getting Running Lights to the Trailer Connector on a 2001 Explorer Sport
    Though we will not have factory wiring diagrams, I am pretty sure I know what is going on and this should be a quick and easy fix. In the passenger compartment fuse box of your 2001 Ford Explorer, there should be a 15A in position 30. This port will handle the park lamp / trailer tow relay and should be all you need to get everything up and running properly. However, in the off chance this does not get you power to the running lamps, let me know and we can try a few other things.

A converter for your vehicle requires a direct connection to the vehicle battery to protect your vehicles sensitive wiring. Bypassing the modulite is not recommended for this reason.
