Video Transcript for Tow Ready Custom Fit Vehicle Wiring 118242 Review

Today we're going to be taking a look at the Ford Replacement OEM Tow Package Wiring Harness with a seven way connector. This product fits numerous vehicles, so to make sure it works with your particular year and model, you can use the vehicle fit guide located on our website at This is an exact replacement for your damaged OEM wiring harness. It's going to install quickly and easily, and it upgrades vehicles from a four flat OEM wiring to a seven way connector. The existing four way flat harness on your vehicle will still be functional. The unit's designed to connect directly to the standard OEM connector, you can see right here everything that it comes with. Your going to get the actual harness, your going to get your new seven way connector, plugs into this port right here on the harness.

Your going to get a hardware kit that's going to include two zip ties, detailed instructions, and your going to get the necessary fuses and relays. The connector right here, to make sure this is easily accessible at the back of your vehicle, we recommend using a mounting bracket. This is going to fit mounting bracket PK-12711U. That item is sold separate if your wanting to add a bracket to the vehicle for your seven way connector. You can find it here at Now when it comes to installing the unit, you'll need to disconnect the vehicles negative battery cable, install the included fuses and relays according to the detailed instructions, locate the vehicles wiring plug that's going to be located in the rear underneath the vehicle, inside the driver's side frame rail.

Separate the plugs on the vehicle, and then install the trailer tow harness between mating plugs. These connectors are going to match up perfectly, they're going to snap lock together for a nice tight secure fit. Once you have those connected, make your ground connection, that's going to be you white wire with the inaudible 00:01:37 attached to it. That's going to get connected by using the existing ground stud on your frame rail, and then plug the seven way socket into the harness on this side. Push it in until it snaps together. It's got the locking tabs on it as well for a secure fit.

Once you have that done, you can reconnect the battery cables, test your installation, you can secure all your loose wires with the included zip ties or cable ties. Then you can mount the tow harness in an accessible location using the mounting bracket like I mentioned earlier. Please keep in mind, the unit can only be used with a factory four pole harness. This will not work with the factory seven pole harness. The instructions are detailed, they include some images in there to help with the installation process. A couple more things that I want to mention before we wrap up the video, here on the seven way connector, you can see it has a nice spring loaded lid, has a little tab right there so you can easily get that open, and get everything connected as you need to.

Really nice design. I just want you to know that your wiring is going to be protected. It's got the nice wire loom that goes around there to protect the wires. Again, when installing this, I do recommend going ahead and using the zip ties, to secure the wires up and out of the way, and keeping them safe. Especially during travel, and when a lot of grim builds up under the vehicle, having them tucked up and out of the way. Maybe even along the existing wiring harness is really going to help extend the life of this wiring harness, and just the wires. That wiring loom is going to help as well. That's going to do it for today's look at the Ford Replacement OEM Tow Package Wiring Harness with a seven way connector.

My F150 had an OEM 4 pin trailer plug and hitch. The 118242 - 7 pin connector with wiring harness is the ticket. The hardest part of the install was dropping the spare tire. The plugs connect directly to the factory plugs and the harness length is the correct length. The 3035-P brake controller connector harness was just as easy. Plugs right in to the OEM plug next to the ECM connector and the other end into the brake controller. The PK12711U-26 - 7 pin bracket and hardware kit fastens directly the OEM bracket that is on the hitch. My truck had an OEM 4 pin trailer towing set up with the hitch. The OEM hitch had the bracket welded on it to attach the 7 pin mounting bracket to it. These kits make this install very easy and professional looking. If I have one complaint, the hardware kit to attach the 7 pin connector bracket is set up to fasten the bracket directly to the bumper with 2 - self tapping screws provided in the kit. The kit also includes 4 #12 machine screws with toothed washer nuts to attached the 7 pin connector to the bracket. This is fine if your truck hitch doesn't have an attaching bracket welded to it. The kit should included in it 6 #12 machine screws and nuts along with the 2 self tapping screws. Since my OEM hitch actually had a bracket welded to it to attach the 7 pin bracket to it, I had to use two other #12 screws and nuts to attach the 7 pin bracket to the OEM bracket on the hitch. Not a big deal, just a thought. It took me about 2 hours, start to finish to install the 7 pin connector, trailer controller, and add the two relays in the OEM relay/fuse box under the hood. I highly recommend these kits. 322339

I do not like to leave bad reviews, however I was initially impressed from what I heard about family members who have used etrailer. I purchased the above product for a 97 ford f150 with factory tow package. This product was confirmed to fit this truck, and was listed as specifically for this truck. However the connectors are not even close, which I can understand considering that the truck was built in mid 96 as a 97 model. I called into customer service after doing a great deal of research, and discovered through ford that there were different variations of electric brake configurations for this year. I needed to return said product, that I purchased based on the websites EXACT description and etrailer wants to charge me almost 12 bucks to return a product that they advertise as "confirmed fit". I would have no problem paying for shipping if this was MY error. Customer service stated that they would request to waive shipping, confirmed my phone number, stated they would call back....never did. One would think you guys would do your homework on this before advertising a product in such a manner. I was easily able to find out that depending on when and where my truck was built would determine what type of harness is needed. 451374

Excellent product. High quality and easy installation. Made better than a factory harness I have on a different vehicle. I also purchased the mounting bracket and hardware kit. The bracket is wonderful and most of the hardware was good too. The self tapping screws both got the heads broke off, but it was my fault, not the screws. 85108


Still working flawlessly, the factory 4 flat isnt working but this one still works like it did when brand new. Highly recommended.

The tow package I purchased last year, fits great and installed perfectly. It works perfectly with my electronic under-dash brake controller. The kit came with everything that I needed and instructions were easy to read I had the entire kit installed in about 40 minutes it's work Flawless for me for over a year and I tow a variety of trailers the plug is never failed due to workmanship it is still water tight. The receiver cap spring still has excellent tension to help hold the plug into place, the only gripe I have is that I should have installed stainless mounting screwswhen I installed the kit because the mounting starting are starting to rust a little, but that's my oversight and is nothing to do with the kit and its ability to provide flawless service. I highly recommend this product if you're like me and was looking for an oem Plug and Play setup! 5 stars! 374842

by: Duane G.06/04/2014

nice plug and play installation, video on your web site helped to speed the process as well as clarified that this was the right part that I needed, very good quality although the maxi fuses were not correct for my application but mine already had the fuses in place. 134345


The product is doing fine.

Installation was a piece of cake. Everything worked exactly like the video explained and everything was in the box to complete the job. The lady on the phone even reminded me to add a bracket. Like everyone else, I tried locally to get these parts. The local guys (Oreilly, Napa, Autozone & even the custom accessory shop) told me this harness did not exist. I've installed several of these style harnesses on different vehicles. This is my first from etrailer and was by far the most complete kit ever. Everything fit perfectly. Instructions and video were exactly correct. Zero regrets. Worth the money. Wish I would have known about etrailer sooner. Big thanks to the local guys for forcing me to shop online. 100769

We purchased a 5th trailer and needed to have my Ford F-150 wired for trailer brakes and 7 pin harness. Checked your website and was able to find all parts I needed. The installaton videos you have are awesome, they help out so much. Ordered all parts and they arrived quickly. All parts were identical to what was ordered. Had everything installed and wired in, in about 45 minutes. They wiring harness was perfect fit and they trailer brake control harness also exact fit. My overall experience was awesome from placing the order and the e-mails to let me know who took my order and who sent it and tracking it. I will recomond etrailer to everyone I can. Thanks to etrailer we are ready to tow our trailer.****** 34253

The product works as described. The only problem I encountered was on a 2001 F150 crewcab. The connector that connected to the wire harness coming from the front of the vehicle did not have any catch mechanism so it wouldn't stay together enough for the right side lights(on truck and trailer) to work. I used some channel locks and pushed together as far as I could without breaking anything then used electrical tape to tape it together. Of course after I crawled out form under truck and put spare back in place I realized I should have used a zip tie to hold it. Would probably last longer and hold better. Everything works well. I do not have a brake controller hooked up on vehicle yet. 113986

Plug and play on my 2003 Ford F-150. Works great. I found the installation video on the website especially helpful. Great job!! 131483


so far so good. no issues.

Installation of the actual harness was easy. However, if you have the factory 4-pin flat connector without the 7-blade connector, you will need to purchase or make a bracket for the 7-blade connector. On an F-150 there is very little space to add an additional bracket, so I extended the 4-pin bracket and made the extension so that it held both the 4-pin and 7-blade connectors. There is a bracket, a Ford part, specifically marketed for the Harley Davidson edition, FY3Z-14A163-CA, which may or may not fit the standard F-150. Also, another part, FL3Z-14A163-BA may or may not fit. 138797

The wiring harness worked great. There are instructions and a video that made it simple. I knew exactly what to do before I started. We needed this in order to pull a larger trailer that has electric brakes and didn't want to cut and splice wires. The connectors plugged right in to the OEM connectors. I only wish I would have thought of it sooner so I didn't have to pay for the next day delivery...but on the other hand Amazon was like a 2 week delivery and Ford was triple the price. I was happy that someone offered next day delivery. 318910

I needed a 7 pin wiring system and a friend told me about I looked at all the options listed for brake controllers and didn't know which to choose from, I called tech support and explained what I wanted and they reccomends a controller for me. I also wanted plug and play, no cutting/skinning/splicing wires for me, I wanted it simple. Well I got simple, very easy install and everything works perfect. Very satisfied and I will be buying more products in the near future. 325943

by: Richard C04/08/2017

This kit was exactly what I needed for my '03 F150 to pull my trailer. It was simple to install and nothing additional was needed in my case. The connectors are usually already there if you have the tow package and a 4-pin. Just remove the spare and the connectors are there and it was simple as pie from there. etrailer is the best place for all your needs and I would highly recommend them to anyone needing parts or supplies for their towing needs. Great products, great company! 364595

Very easy to order. Came on time and was exactly as it said it would be. Very simple to hook up and in minutes my problems were solved! Previous plug that was on my truck was installed incorrectly by previous owner. I hooked up a brake controller for my pull behind camper and could not get power to the controller. After installing the correct plug and harness that I ordered from your site the problem was fixed literally in less than 1 hour. Thanks for making it very simple! 271591

7-way harness has a weak locking tab on back of connector which locks it into the back of the socket. It promptly broke while handling connector and socket prior to assembly on vehicle. The 30-amp fuses included were of the wrong type for a 1999 F150. The fuses are a blade type maxi-fuse, and the 99 F150 uses a square type of fuse. Luckily, both fuses were already installed in the vehicle. The relays fit perfectly. 83591

This was great, I bought it for my 2000 ford f150. It was easy to install. Only trouble I had was securing the ground to the frame as my ground bolt was corroded with rust (live in Minnesota) such that I couldn't loosen it and had to drill a new hole for the ground. Another note I bought the mounting hardware as well, and it was the wrong mount so be careful and make sure you get the right one if you order the kit 108425

by: Mike F.09/22/2016

If you did not see my review for the bracket then I will recap. I did not use the bracket except for a template. Mounted the plug in the factory bumper just left of the license plate recess by knocking it out with an electrical knockout cutter. Drilled the mounting holes and installed the wiring harness. Great product and great video, I highly recommend Package properly, came early, fit was perfect. 297816

by: Nick T04/19/2016

I put off wiring my truck with a 7 way plug for years because I didn't want to deal with the hassle...WRONG. I found this somewhat accidentally and installation was easy. One word of caution; read the short instructions twice so you don't get worried if you have extra parts. My installation did not require the two blade fuses (but of course that was clearly stated in the instructions). I am very pleased. 246130

by: Mark11/08/2013

Your product fits perfectly I customize the 7 way plug into my bumper I didn't like the way the bracket let hang down so far ill send another picture with me pulling my drag truck with the van thanks again. 106753

by: Jason m08/14/2017

Great prices good informative info about makes and models and what parts are compatible and how to install every part or piece that you guys offer on your web site. Wish I had found a few vehicles earlier I would have saved a lot a money and would have gotten better quality equipment, almost made dummy proof if you can't install items you got from etrailer it's not thier fault 420100

- 118242

by: Chris M09/13/2016

Simple install! Took longer to get the spare tire off then the installation of the harness did. Make sure to purchase the mounting bracket (sold separately). I also bought the no drill mounting bracket, but chose to use self tapping screws and went straight into the bumper. Makes it easier to hook up, and it's solid. Your choice if you want to save $9. Great product, fast shipping. 294196

by: Gary Miller09/08/2016

The turn around on this order was awesome. I haven't instaiied it yet but it looks simple. I was a little disappointed that there was no mounting bracket with this, but no fear I'm going to bore a hole it the bumper and with some self tapping screws we will be up and running in no time. I'll post some pictures of the completed job. Thanks for your excellent service 292605

if this was any easier to install i think i could have did it blind but everthing went in place very easy no problem if you take your time it might take 1 hour that saying you have the tools on hand that you will need their video are very helpful if you find you are having a problem but i think evening a cave man could install this great products.happy happy happy 114296

by: Mine R.10/03/2017

Seems to be a quality part. Arrived ahead of time and was priced good. But it does not match up with my 99 Ford F-150 stepside. There is no pig tail for the rear lights and now I have no brakes blinkers or anything. Well that was the reason for buying this because the original harness was destroyed. Is there a different harness I should have gotten? 438750

- 118242

by: Bill McC05/14/2013

Great purchase all around. Paid a pro (?) to install electric brakes but he didn't do it right. I ordered the harness myself and installed myself then took it back to the pro (?) to have him test it and now is he embarrassed. With the video online I should have done it myself from the beginning. Thanks ill be back when I need something else 80127

by: Mark05/19/2011

The wiring harness was easy to install. Several fuses and relays are included, but the instructions are generic to cover a wide range of trucks. Depending on the year and options on your specific truck you may use all or only a few of the fuses and relays. This was confusing and I hope I got the correct pieces in the correct locations. 14837

by: Al G.07/08/2012

I ordered the prodigy 2 controller, the wiring harness, hardware kit and mounting bracket. quick shipping and instalation was super easy with the how to video. I installed the whole kit in under an hour and towed 1650mi right off. Just as described and the kit worked flawless! literally plug and play. I can't say enough good about it. 47149

- 118242

by: Jeff M06/10/2017

Great product and easy installation. The only issue was that they included some huge fuses that did not fit my 2002 truck. Instead I needed smaller square ones. Otherwise this was a very easy installation, once I got the spare tire down. I have no problem recommending this connector. And, etrailer shipping was good as well. 391358

- 118242

by: Nick L05/29/2013

Very easy to install thanks to Ford. Very disappointing that it did not come with the $4.00 mounting bracket for the back of my truck. Had I been told this during the order process I certainly would have bought it. Its bundled with enough relays/fuses that it should've been bundled with the bracket. Thats the only complaint. 82299

Easiest trailer plug I have ever installed...lowered spare tire (but did not remove) and then unplugged the stock wire plugged this in line and mounted it all to the brackets i purchased here at same time, had it all wrapped up and completed in under half hour, with my 4 year old daughters help of course! 187455

by: John Malkin - Denver04/03/2014

To be honest -- the hardest part was finding the key for my spare !!!! Found it though and within 20 minutes I was in parking lot checking the brakes. Takonsha P3 coupled with eTrailers wiring harness and accessory make this a great DIY project. Don't forget to purchase a mounting plate !! 123583

Worked great. Ordered it on Tuesday, got it on Friday. It was the perfect length for my 2000 F-150 and all the connections, fuses, and relays fit perfect. I like that the instructions and video were posted on your website so I knew exactly how to install it before I even ordered it. 36240

Bought this for my 2000 F 150 Off Road to hook my camper lights up. It was fairly easy too hook up, broke on clip that I had to tape. It worked well for a while then one light quit working and I ended up having to spice into it to get it working again. All in all and ok product. 407644

Product was as described. Easy to hook up. The only thing that is not clear is that it does not come with the L bracket to mount it to the truck. I went to our local store and their L bracket will not work with this plug, so don't forget to order the bracket as well. 24280

quick shipping, easy install this sysytem couldnt be simpler, unplug a connector, pug the adapter into the two ends and run the bolt through the ring termional and tighten back in place. a basic mounting bracket for the recepicle would have been handy however. 2142

The harness I purchased for my 2002 Ford F-150 was fine with no problems installing it. However, it did not solve the problem I had (no right stop/turn signal and no running lights). I suspect the problem lies elsewhere and is no fault of the new harness. 337573

by: R Rrebbs03/16/2011

The install could not have been easier, unless you had some one else do it. Fast shipping and the E trailer customer service is great. The only problem I had was I forgot to order the mounting bracket mount bolt/screws. The video was made install easy. 9442

My truck already had 7 pin harness but had a ground issue. Replaced it with this one and it works great now. Plugged right in but had to leave old harness in to get taillights to work. Way less expensive than buying OE harness from Ford Thanks etrailer 436066

Fits great and no fuss plugs. Added a little Dielectric grease for good measure and have had no issues. well worth the extra money over a "Universal" mount. all the wires had been well terminated and low resistance. Clean install clean look. 8000

I mistakenly bought the wrong product the first time. I small print the first one said it was not for the Heritage body 2004 F150. I ordered the correct one and it worked great. The product should be better identified online. 324059

  • How to Determine the Factory Trailer Wire Functions on a 2005 Ford F-150
  • I may have some information that will help, however, vehicle manufacturers are notorious for changing the wire colors on their factory trailer wiring, so the best way to determine the function of each wire is by testing. To test the wires, I recommend using a circuit tester like part # 40376. Find a good ground for the tester and test each wire as a helper activates each light function on the truck. We had a 2006 Ford F-150 on our lot with the factory tow package wiring, so I went to...

  • What Do The Fuses And Relays Control On Tow Ready Ford OEM Tow Package Wiring Harness # 118242
  • The fuses and relays that come with the Tow Ready Ford Replacement OEM Tow Package Wiring Harness, 7-Way, part # 118242, does not control the cruise control, power mirrors, or the fog lamps. The two 30 amp maxi-fuses are for the Trailer Tow Electric Brake and Trailer Tow Battery Charge fuse locations. The two relays are for the Trailer Tow Backup Lamp Relay and the Trailer Tow Battery Charge Relay. The fuses and relays are located in the vehicles power distribution box (and trailer...

  • Fuse and Relay Locations for Tow Package Wiring on a 2006 Ford F-150
  • On your 2006 Ford F-150 there should be fuses and relays used for the tow package wiring. Since the trailer lights do not work but the brakes do, it does sound like a fuse or relay problem. Under the hood, the #10 fuse is for trailer tow backup lamps and parking lamps. Fuse #36 is trailer tow right turn/brake lights. And #42 is trailer tow left turn/brake lights. Location #106 is for the 12 volt circuit to the trailer connector. For relays #R05 is the 12 volt circuit relay. Location...

  • Troubleshooting Trailer Turn Signals With 1997 Ford F150 With Factory Wiring Harness
  • You can check the mini fuse panel located behind the power distribution box. There should be a 20 amp fuse in location 2 for the trailer tow stop/turn lamps. Also, in the power distribution box, there is a 40 amp fuse in location 16 for trailer tow battery charge and stop/turn lamps. If this fails to correct the problem you can troubleshoot. The best way is to disconnect the truck and trailer and test each one individually. If you happen to have access to another truck or trailer that...

  • Troubleshooting a Replacement Ford Tow Package Wiring Harness for No Left Turn Signal
  • I would try unplugging the harnesses and relays and then plugging them back in as it sounds like the left turn signal circuit is not making contact somewhere and it could be as simple as reconnecting the harness to fix the problem. Next. I would check the vehicle side plug that the Tow Ready Custom Fit Vehicle Wiring # # 118242, plugs into. If this circuit is functioning properly then check the wires coming out of the new connector to determine if the power is getting to the 7-Way harness....

The rest are under the hood in the power distribution box. Under the hood location 6 is the trailer parking lamp relay Location 9 is the trailer battery charge relay Location 17 is another brake controller fuse Location 21 is the fuse for the trailer battery charge circuit Location 31...

  • Replacement 7-Way Wiring Harness for 2003 Ford F-250 and 350 Super Duty
  • We have part # 118243 that is meant for SuperDuty trucks, this should be the part you are looking for. This will plug directly to your factory setup and is a very simple install. I have included a link to the instructions for this part. We have another part that may also be what you are looking for, but requires some hard-wiring, part # ETBC7.

  • Recommended Trailer Harness for 2003 Ford F-150
  • If your 2003 Ford F-150 came from the factory with the 4-Way flat connector, then your truck already has a towing package wired in. In this case I would recommend 7-Way connect part # 118242. A 7-Way will allow you to tow trailers with 7-Way wiring systems and brakes. You can still use it with 4-Way trailers by using an adapter like part # 47345. Built into this adapter is a circuit tester to make sure truck wiring is hooked up properly. If you strictly want to use a 4-Way, then the...

  • Installing a Brake Controller on a 1998 Ford F-150 with Factory 4-Way Trailer Connector
  • If your towing package includes a 4-Flat connector, you will first need to add a 7-Way. For your 1998 Ford F-150, you will need the Ford Replacement OEM Tow Package Wiring Harness, # 118242. Follow the wires from the 4-Flat towards the front of the vehicle until you find a connection point, usually on the driver side between the rear tires and the end of the truck bed. There will be more wires going into the connector then coming out. You will disconnect the factory connection and plug...

  • How to Unplug a 7-Way Harness from the 7-Way on a Ford Super Duty
  • Do you see the white plastic piece in the shape of a U in the picture that you sent me? You will need to pull that piece out away from the harness to release it from the rest of the 7-way. Check out the video I attached and skip to the 3:25 mark to see how it unlocks and locks.

  • Finding Fuse and Relay Locations for Tow Package Wiring on a 2005 Ford F-150
  • If you look at the owners manual for the truck and/or the legend on the power distribution box lid it will tell you the locations of the fuses/relays that are related to the tow package wiring. I found an online version of the owners manual and the fuse/relay section starts on page 224. For fuses it looks like the trailer tow parking lamp fuse is in location 10 and the relay is location R201.

  • 2012 Ford F-150 with Factory Came with Fuse and Relay Labeled AL3T-15A416-AA
  • Normally, a factory tow package will be fully functional from the factory when you buy the truck. But in some cases, a tow package can be added very easily (by plugging in a 7-Way and adding some relays/fuses) that they can provide the parts at the dealer. It sounds like your truck may fall under the second category. To be sure, all you have to do is use the owners manual to find the proper locations of the fuses/relays related to the tow package, and insert the ones you found (if needed,...

  • How to Install 7 Way Trailer Wiring on a 1997 Ford F-150
  • It sounds like your 1997 F-150 does not have the tow package wiring so the wiring harness # 118242 will not work on your truck. To install a 7-Way trailer connector at the back of your truck, you will need to start with a working 4-Way connector, # 18252, or # 118344 if you have a stepside. If you need to splice to connect the 4-Way, use a circuit tester to splice to the appropriate wires you found at the connector on the frame rail. If you have a 4-Way connector at the rear of your...

  • Fuse and Relay Locations for 12 Volt Power on a 2011 F150 with Tow Package
  • I would start by checking for a missing relay and/or missing/blown fuse. I found the 2011 Ford F-150 owner's manual online with the following information. The fuse and relay that you'll need to check is located in the power distrubution box. (Location: 9 - TT Battery charger relay) (Location. 21 - TT Battery Charger Relay Power 30A Fuse). If there is no problem with your fuse or relay, then I would test your truck's 7 way connector for 12 Volt power. You can test that connection...

  • Troubleshooting Running Lights on Trailer Not Working When Connected to a 2001 Ford F-150
  • If your 2001 Ford F-150 is equipped with a factory 4-Way trailer connector, the Tow Ready Custom Fit Vehicle Wiring, # 118242, should work. There are a couple of things you can check. First, there are a few fuses that need to be installed if you have not done so. I have included a link to the instructions below. The first few steps address the fuses. Also, you can check to see if any fuses are blown. A tow package running light fuse might be blown and need to be replaced. Also, check...

It should be located towards the center of the dash and may be tucked up and out of the way behind some wiring. I have linked an FAQ Article that shows the location of the plug. You will need the Ford Adapter, part # HM47715, to plug into the brake controller harness and the Ford plug under the dash.

  • Troubleshooting the Trailer Wiring Reverse Light Wire on a 2005 Ford Expedition
  • If the additional blue wire is a factory installed wire and not a wire ran by a previous owner, then the issue is typically caused by a blown fuse or a bad relay. On your 2005 Ford Expedition, there should be a 20 amp fuse for the trailer wiring backup lamps is fuse position 10. If that fuse is blown or missing, that could be the issue. I also recommend checking the relays in position R201 and R301. If the fuses and relays are present and in good condition, it may be possible that the...

  • Installation of Brake Controller On My 2011 Ford F-150 Without Tow Package
  • It is possible that the wires you are looking for have been terminated farther up the frame rail or may not have been ran back. Typically the wires would run to where the factory 4-way is plugged into, usually near the spare tire. If you cannot locate the wires, you will just need to hardwire the brake controller and 7-way, which is not as bad as it sounds (we have a kit for this). You will need the Brake Controller 4 and 7-way Installation Kit, part # ETBC7. To install, you will begin...

This is part plug and play and part hardwire, but the hardwire locations are easy to access. You will need to ground the white wire to the vehicle frame. The purple wire is for reverse lights if needed. You would need to tap into a reverse light wire on the vehicle. The blue wire is for the trailer brakes and the black wire is for 12 volt power. To connect these wires, follow...

  • Troubleshooting Running Light Circuit on Trailer Pulled by 2001 Ford Expedition
  • If you have tested and are getting voltage at the trailer connector when the brake lights and turn signals are activated, you most likely have a blown fuse. Check the fuse box under the hood. The box should have a legend on the underside of the lid that identifies the circuits, or you can check your owners manual for the proper fuse location. Keep in mind that on some Ford trucks and SUVs, the fuses for the tow package are located in a separate fuse block mounted on the firewall in the...

  • Adding a 7-Way Trailer Connector to a 2011 Ford F-150

If you follow the factory 4-Way wiring under the truck you will see where it plugs into another harness. The wiring for this other harness will have a 12 volt power wire and an output wire for trailer brakes. Pull back the protective covering over the wiring for this forward connector to find them. The power wire should be orange...

  • 7-Way Trailer Connector for 2011 Ford F-150
  • The wiring harness you referenced, part # 118242 would not be compatible with your 2011 F150. It is designed for the 1997-2003 model years only. The parts necessary to provide a 7-way for your F150 would depend on how it was equipped when it left the factory. If your F-150 has the factory round plug located along the drivers side frame rail behind the back bumper, you would use part # 74682. The factory plug will have a dust cover that will need to be removed, and the 74682 would...

  • Options for Installing 7-Way Trailer Connector on 2004 Ford F150 Equipped with 4-Pole
  • Although the # 30717 will work, I have a better suggestion for you. If your F150 is the New Body style, use part # 118247. If you have the Old Body style, use # 118242. Either connector will plug inline with your existing trailer connector, allowing you to retain the function of your existing 4-pole. Either kit includes the necessary fuses and relays to activate the remainder of the tow package circuits. Granted, this is a more expensive option, but it will be a very quick and easy plug-and-play...
