Installation

This custom-fit T-One connector plugs into your vehicle's wiring harness. You will have to remove some interior paneling to access this harness. The connection point for the 7-way tow harness is located behind the rear bumper, on the driver's side. The Modulite plugs into the factory wiring harness within the driver's-side storage compartment in your rear cargo area. Once you've plugged in the Modulite, insert the included fuses and relays into your fuse panel as indicated in the instructions.


Once installation is complete, the 7-way connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.


It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 7-pole connector itself - to help prevent corrosion.


ModuLite Powered Tail Light Converter

A ModuLite power module is built into this T-One connector. Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are compatible with the wiring system of your trailer. This power module functions as a tail light converter to combine the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.


With a ModuLite, your trailer's lights will be powered without overloading your vehicle's electrical system. Because the module draws power directly from your car's battery and bypasses the electrical routes that are used by a basic wiring harness, there is virtually no draw on your tail light circuits.

Video Transcript for Trailer Wiring Harness Installation - 2010 Honda Pilot

Today on our 2010 Honda Pilot, we will be installing the tow ready; custom fit wiring with seven pole connector, part number 118253.For you 00:00:12 to install, weve first going to go ahead and show you the mounting options for our new seven pole connector. Our first option, take the seven pole connector, put it up to the rear bumper fascia at the knockout and then trace out the socket of the connector. Once we have it traced out with our yellow paint marker, we will then go head and take a rotary tool and cut out this section. Now with the cut out, we can the go ahead and take the seven pole connector and mount it directly to the rear bumper fascia without removing the manufacturers knockout.This can be done by simply using the self-tapping screws. Next we will go ahead and remove the seven pole connector and the self-tapping screw and show you how to remove the knockout and secure the seven pole connector in position using a seven pole bracket. Our first step will be to go ahead and cut out the manufacturers knockout.

Using a utility knife, we will go ahead and cut the tabs that secure it in place. Then we will cut the bracket and behind it.Two easily available options for mounting our seven pole connector using a seven pole bracket will be the Draw-Tite seven pole mounting bracket, part number 18138 or the Pollak seven pole universal mounting bracket with slotted attachment points, part number PK12711U in conjunction with the Pollak seven pole bracket hardware, part number PK11926.For our application we will be using the Draw-Tite mounting bracket along with self-tapping screws. Once we have it lined up, we will then go ahead and take our paint marker and mark out the attachment points where it lines up on the bracket. Then we can go ahead and remove the bracket and seven pole connector and using a couple of pliers or vise grips, secure the two together and use the self-tapping screws to mount the seven pole connector directly to the seven pole bracket.Once you have it secured, were then ready to go ahead and install the seven pole bracket and connector back into position and we will mark out the attachment points. Now that we have these attachments points, because its not a straight shot, I recommend, go ahead and make a couple of pilot holes.

Well now go ahead and remove the rear bumper fascia push-pin fasteners.To remove the fasteners, well pry out in the center and then remove the fastener completely. With both of them removed, we can then pull back on the fascia to gain a little easier access behind the fascia. Now well go ahead and make our pilot holes. Once our pilot holes are made, well go ahead and put the seven pole bracket and connector back in position and then secure it with the self-tapping screws.Now, though we have our bracket secured, were ready to go ahead and install the wiring for our seven pole connector. The wiring will route from the manufacturers tow port above the tail pipe on the drivers side over to our seven pole connector.

Before we can route the wiring, well need to first remove the weather protective cap on the manufacturers tow port connector.Then you can use a flat blade screwdriver to walk it off or a pair of pliers to pull off the cap. Note, over time these can build up with some debris and become very difficult to remove. Once removed, we can now go ahead and take the new wiring harness that was supplied with our tow ready custom install kit and plug the grey connector directly into the manufactures port. Then we will run the other end of our wiring harness to the back of the seven pole. There we can make the connection with the seven pole and lock the grey locking tab, securing our wire to our seven pole connector.Next we will go ahead and secure the wiring harness that we just routed.

We will feed it behind the fascia bracket and then secure it with the black zip tie provided with our install kit. Now with everything routed and run, we will go ahead and cut the access from our zip tie to clean up our install look and reinstall the push-pin fasteners. Next we will move inside the vehicle, then we can open up the interior access panel on the drivers side.Then we will remove the interior door to gain access to the manufacturers wiring behind the interior door. The grey plug and black electrical loom 00:04:24 with the blue tape around it is the manufacturers tow port that well connect our converter box to. Once we have the converter box connected and stored, well go ahead and reinstall the interior door and close the interior access panel on the drivers side.Next well need to locate the manufacturers auxiliary fuse port. It will be just forward of the rear cargo compartment and we can remove the fuse cover panel with a flat-bladed screwdriver. Once removed, well then need to remove the fuse panel cover. Well pry down on the lower locking tab, pull the cover up releasing the lock on the top, and then setting it aside. Next we will start installing the fuses.Our first two fuses will be the red 7.5 amp fuses. The third fuse will be a yellow 20 amp fuse. Next we will install the two relays provided with our install kit; making sure that we install the spade 00:05:22 terminals into the correct positions. Now with both relays installed, well go ahead and reinstall the fuse panel cover in the interior trim 00:05:30 panel. Next well go ahead and move to the engine compartment.Well locate the manufacturers fuse box next to the battery. To remove the fuse box cover we will press on the three locking tabs and pull directly up. Then well locate two fuse positions; one, for a 20 amp fuse and the second, for a square 30 amp fuse. Well go ahead and install our 20 amp fuse first and then our 30 amp fuse. Now with all our fuses installed, well go ahead and reinstall the cover and were ready to hit the road.That does it for the install of the tow ready, custom fit vehicle wiring harness with seven pole connector, part number 118353 on our 2010 Honda Pilot. .

My saviors! Trying to get out of town with my newly built teardrop camper and found my Honda Pilot had no tow light assembly. Not a single Pilot towing kit to be found in Tucson. $180 for the kit to be ordered from Honda. Half the price at Etrailer AND ARRIVED LESS THAN 24 HOURS ON NEXT DAY SHIPPING. Thanks for helping me get out of town almost on schedule. 653760

This product was fantastic! Everything went as expected when installing the wiring harness. All the plugs on the vehicle were exactly where the instructions said they would be, and everything fit good and tight just like an oem product should. The online install video was also a great help. I would highly recommend this to anyone! Make sure and pick up the mounting bracket while your at it, or you'll waste 3hrs of install time trying find one locally (like I did). Thanks for the great product!! On a side note, if you intend to use a brake controller with your setup, there is an extra fuse you must install to make the brake controller work. None of the instructions for this wiring harness, or the brake controller adapter, said anything about it. In the fuse box under the hood, there is a slot labeled "E. BRAKE 20amp" or something along those lines. The 7-pin hookup will work fine without it, but there has to be a fuse here for the brake controller to work!! 60589

I was quoted $181 for this same equipment from several different Honda dealerships. Add in another $110 for the install they said for a total of $291. I am the farthest thing away from a "car guy" and installing stuff myself. I figured I would give this a try though on my own and am happy to say I saved myself over $200 by doing so. The video online via etrailer and the instructions were extremely helpful and I was able to install this no problem in about 20 minutes. Etrailer had this part to me quicker than I expected which was awesome as well!!! Will definitely buy from here again. 147093

I installed this harness for my Honda pilot 2011. No issues for the most part. Had trouble figuring out how to open the rear aux fuse box but eventually found the post on this forum from etrailer expert regarding how to open it. I wish this product came with a clamp that fits into the original screw holes to install the harness connector on the back. Also had to install the extra 20 Amp fuse that comes with this product in the fuse box under the hood upfront. It was too much hassle to install the clamp therefore used zip ties to install the harness connector. 691754

They could not make this easier. Video was straight forward and easy to follow (I did the outside screw mounting method and seems to work just fine and much easier to do). Took me about an hour to pull all tools out, get everything done, and then put everything away. Would have taken much less time but getting the factory harness cap off took some time (they were not kidding that it gets stuck). I finally got it by using a clamp like the video BUT also wedging a flathead screwdriver in the crease and twisting to help pop the cap off. One question I do have out of curiosity if someone could answer. Why provide the extra 20amp fuse but then we leave the one 20amp brake fuse slot empty? In what scenario would I put the 20amp fuse in that 3rd slot? 664285

I watched the video before purchasing and the ease of insaillation helped me decide on which one to buy. The install was easy and took very little time.

Great product, and truly a plug and play.....The product details and instructions were more geared for the Pilot, and very lacking in the image department.....But one video watched cleared any confusion up.

Well product is just what I was looking for. The big issue I had was locating the accessory cable from under the dash. Everyone just said look under the dash for a blue taped bundle. Ya right, I had to almost dismantle my dash, just so I could get my big head under the thing. Then it took my over an hour to locate the needed harness from under the dash. It was hiding up at the top of the wire harness out of my reach almost. But other wise the kit was great. Cheaper then OEM and still working. I would recommend this product to everyone. 555356

  • Which 7-Way Trailer Wiring Harness Fits 2014 Honda Ridgeline
    The reason you are having a hard time installing the Curt 7-way C56366 on your 2014 Honda Ridgeline is that it was designed to fit newer versions of the Ridgeline but not your 2014 model. Instead the correct 7-way harness you need is the # 118253 which comes with the correct converter box, harnesses, and relays. I attached an install video for this harness on a similar Ridgeline which will walk you through the entire process.

  • Can Honda Pilot Wiring Harness 118253 Be Used to Release Trailer Brakes when Backing Up
    Part # 118253 is only to be used with Pilots that have the OEM Tow Package. If you do not know if your Pilot has the OEM tow package, you can contact your dealer or Honda with your VIN and they should be able to tell you. If you does, you would then use adapter part # A75TB to come down to a 5-Way. If you do not have the tow package, you could use part # 118491 and then add a 4-Pole to 5-Pole adapter like part # 20036. You would run the loose blue wire to the tail light circuit on your...

  • Trailer Brake Controller installation in 2010 Honda Ridgeline Without Factory 7-Way
    Your 2010 Honda Ridgeline will have an under-dash connection port for a trailer brake controller like the Prodigy P3 # 90195 only if it came from the factory with the 7-way trailer connector. Adding this connector using kit # 118253 does not provide the brake controller port. This part is intended as a factory replacement but not a retro-fit. For any vehicle that does not have the factory-installed 7-way and the under-dash port a brake controller installation will be hardwired. This...

  • Troubleshooting Replacement OEM Wiring Harness # 118253 for 2009 Honda Ridgeline
    You can replace the lights on your trailer with LEDs and run fresh wiring through the 7-Way # 118253 on your 2009 Honda Ridgeline and the 7-Way on your trailer, but before doing that I recommend checking the fuses to make sure that they were all installed properly. You can also use a Circuit Tester # 40376 to test all of the functions on the 7-Way on your Ridgeline to see if it is fully functioning. The fuse box you will want to look at is under the hood. You will need to remove the...

  • Does Trailer Wiring Harness # 118253 Come with a Mounting Bracket for a 2013 Honda Ridgeline
    Trailer wiring harness # 118253 is OEM in that it plugs into the factory wiring harness on your 2013 Honda Ridgeline. It does not come with a mounting bracket but you can add one using # PK12711U.

  • Troubleshooting 7-Way Wiring With Modulite On 2009 Honda Pilot
    You will want to check your factory 4-way plug to make certain it is functioning properly on your 2009 Honda Pilot. Unplug the new harness and test the 4-way plug by using a circuit tester like part # 40376. Test each pin to make sure everything is working properly with the trailer disconnected. If that checks out then you need to connect the new harness, and make sure all of the relays and fuses have been installed properly. Use the circuit tester to check that all of the wires leading...

  • Trailer Wiring Harness Not Working on 2011 Honda Pilot
    Replacement 7-Way trailer connector # 118253 can be used with the 2011 Honda Pilot. The harness that you have now might not be working if one of the fuses or relays is bad or is not installed in the correct place. It is not likely that a fuse or relay would be bad on a new harness but you can check them. The fuses are easy to check but the relays are harder. Basically the only way to test a relay is to use a known good one in place of a potential bad one. There could also be additional...

  • Wiring to tow a Pair of Trailers With a 2009 Honda Pilot
    The Honda Replacement OEM Tow Package Wiring # 118253 will upgrade your 2009 Honda Pilot with tow package from a 4-way to a 7-way, and you'd need mounting bracket # PK12711U to mount the 7-way. This bracket now comes with the mounting hardware included so the other part you mentioned is not needed. To go from a 7-way to your boat trailer with a 5-way and utility trailer with a 4-way you would want the handy 7-Pole to 4-Pole and 5-Pole Adapter # 37385, which will fulfill all of your wiring...

  • 7-Way Trailer Wiring Harness Recommendation for a 2011 Honda Pilot
    We do recommend 7-Way Tow Package Wiring # 118253 for the 2011 Honda Pilot models but it isn't a great fit due to fit issues with the factory cut-out in the rear fascia. However, it can still be used but the 7-Way plug and housing will not fit as well as it does on a 2010 model. We also have Replacement Circuit Protected OEM Wiring Harness # C56366. This kit includes a mounting bracket for the 7-Way so it does not use the factory cut-out on the vehicle. I have included links to the installation...
