Video Transcript for Tekonsha Trailer Wiring Harness Installation - 2014 Audi Q7

Today on your 2014 Audi Q7 we're gonna be installing Tekonsha's heavy duty ModuLite vehicle wiring harness. To help us complete that installation, we'll be using Tekonsha's ModuLite installation wiring kit. This wiring harness is gonna provide you with all the necessary lighting that you'll need on your trailer to be DOT compliant in all states. This includes your left turn signal, right turn signal, tail lamps and brake lamps. This way, you can be ensured that when you're going on your vacations, trip, or just doing work around the area, that you're gonna be safe and everybody around you is gonna know what your intentions are because they'll be able to see all of your turn signals. There's a module that's installed in your harness that monitors the signals that are going to it and the module itself is what sends it out to our four pole connector.

What's nice about this is if there's any faults on your trailer, the module will shut it down and prevent any damage from occurring to the wiring on your vehicle. As a further step of protection, there's a fuse that's installed in your harness.So if the module does not shut the circuit down in time, the fuse will open for your wiring harness and nothing else on your vehicle will be affected. Now when you're all done using your harness, it's gonna live inside the vehicle. Your lift gate opens up. You can then wrap up your harness, tuck it into the storage compartment next to your module right there and reinsert the cover and you're all set.

When you're ready to use your wiring, you simply drape it out over the back and close your lift gate. It'll pinch down in between your weather stripping. You want to make sure you just stay away from the inaudible 00:01:38 in the middle and you see we have plenty of length here that will allow us to connect to our trailer. We'll begin our installation at the back of the vehicle. We're gonna need to tap into both the driver and passenger side tail light assemblies.

To access these, we'll want to open up our lift gate and we're gonna need to remove the trim panels back here. We'll start with the small access panels.To remove the access panels, you'll want to use a trim panel remover tool or a flat bladed screwdriver. You want to get behind it. Pop it out. Once you've popped it out using the little access point there, you can work your way down the side until it just pops off.

We're gonna do that on the other side as well. We'll then need to remove the trim piece that goes across the top here. You'll need to remove a screw from the center hook here in the middle of this panel. You'll want to use a small pick to get underneath the cover and pop it out and then we're gonna remove the bolt that's located there using a T20 torque socket. We can now pull this panel off. Simply get your fingers behind it and just pop it out. Then pull down here in the middle and we'll take the side pieces off on each side. There's gonna be one bolt you'll need to remove with a T25 torque socket and then this one just like our centerpiece will just pull off.Just kind of work your way down and we'll do the same thing on the other side. We'll now have several bolts on our back panel here we're gonna need to remove. There's gonna be one on each side underneath the access covers you removed and there will be four across the top here and then underneath this panel here, simply twist that and open it up and you'll find two more in there. We're gonna use the same size torque socket to remove all those. Now that you've got all those removed, you can begin pulling your paneling off. I recommend using a trim panel tool to help assist you pulling it off. Starting on one side, just pop the hardware out of there. On the backside of your switch, you want to disconnect the electrical connector. You want to push in on the release tab and pull that out. There's also a light located here. You'll need to reach up and disconnect that as well. There's pushpins on each side of that connector that you need to release to get it off. Simply just pull those back and it'll pop out. We'll now begin making our necessary connections.You'll have quick splices that come in your kit. You'll want to open those up. It's just a little connector that pops down and we're gonna be doing the driver's side first. So we want the yellow and brown wires. Our yellow wire is our turn signal wire. The yellow wire will connect to the blue and red wire on this side. So we're gonna take our quick splice. We're gonna slide the yellow wire into the one end where it cannot push all the way through and the end where it goes all the way through, we're gonna slide that over that blue and red wire. Once you've got that all slide through like that, you'll take a pair of channel locks and you wanna squeeze the metal tab into the wire. Once you've got that squeezed on, simply take the cover now and wrap it around until it snaps in place. In our brown wire, we're gonna do the same thing and it's gonna connect to the gray wire with the black stripe. Now make sure you don't get that confused, as there is another wire here that's black wire with a gray stripe.We do not want that one. Make sure it's the gray wire with the black stripe. That's going to connect in the exact same way and close it shut. We'll then take the red wire that comes in the kit. We're gonna strip it back and crimp on one of the ring terminals that comes in the kit. We're gonna be using the medium sized one, as we're gonna be grounding this here. So you wanna select one that's gonna be appropriate to fit on there. It's not gonna be too large or too small. We'll slide that onto our red wire and crimp it down. Where we just made our connections, if you go up the pillar, you're gonna find your ground stud there. Remove that bolt with a 10 millimeter socket. Take your white and red wire. Slide those onto your bolt. Make sure you get all the wires that we're already on that bolt back on the bolt and then just reinstall it. We'll go ahead and mount our module now. We're gonna end up putting it right here behind this panel next to our connector. So use the sticky pad that comes in the kit.Stick it to the back of your module. Remove the adhesive backing and adhere that right next to the connector there behind this cover. Now we're gonna take the green wire. It's gonna run across to this side and we're gonna make our connection the blue and red wire that's on our passenger side here. We're gonna make this connection exactly the same as we did on the other side. Now we'll take the black wire from our kit. We're going to strip it back. We're gonna crimp on the yellow butt connector that comes in the kit and the other end of our black wire here is gonna hook to the black wire with the red stripe coming off of our module. It is pretty stripped. But I like to strip just a little bit more back and we're just gonna crimp it right onto there and this black wire's gonna go to our battery positive source. Now the battery on your Q7 is gonna be located underneath the seat. You can kind of get a glimpse in it if you pull out this panel here.But to access it, you have to remove the entire seat from the vehicle. So to avoid all of that extra work and potential trip to the dealer, if anything goes wrong, we're gonna be routing ours to a fuse panel located in the back. Back here on our passenger side, you'll see your 12 volt outlet. If you pop this panel out, there's actually a fuse panel located back here. We'll be using a fuse tap, which you can purchase here at etrailer.com to save us a lot of time and headaches trying to get it to the battery underneath the seat. We can simply plug it in to our fuse panel and this wire will now be live when we insert a fuse into it, giving us the power we need to run our vehicle wiring harness. Now I do want to let you know it doesn't really matter which slot you use. I prefer to use the one furthest back because it's got this plastic edging around here, which can interfere with the fuse tap.But it fits perfectly here between these fuses and I want to make sure that when you insert this, you have the wire end sticking out the bottom because the open slots here only have power on the top and we want our power to be on this fuse and we want our power to be on this terminal here so that way it has to go through the fuse to get out of our wire, making sure that we are gonna be circuit protect. So it must go this way. We then took our wiring. We clean it up with the zip ties that come in our kit and we began routing it down over towards our passenger side. Once we get the wire to our hinge on the passenger side, we want to take the cover off here. It just pulls off. Just kind of work it off there. We're then going to zip tie the wire to this wire here. We want to try and make sure we got the same form as the wires that already exist there, as this hinge does move.So we want to make sure that our wire we're running is going to move with the existing wiring. We're gonna actually just take this and we're just gonna poke it down underneath our weather stripping here. So if we just push it a little bit down in there, lift up the weather stripping, we can actually get it to go right between it and underneath of it and we're just gonna run it down the weather stripping, tucking it underneath as we go until we get down to the gray fabric portion here. Here, we're gonna poke our wiring inside. So we'll use our trim panel tool. We want to go between the weather stripping and the gray paneling. We're gonna pry it out just a little bit. We just need enough to get the wire to poke through to where we can grab it on the other side. We'll then just flip the weather stripping over our wire and now it's completely hidden and our wire is down here by our fuse panel where we need it. We'll then take our excess black wire, trim it off.We'll strip back the black wire and we're gonna de-crimp that onto our fuse terminal here. We can then take the fuse that comes in our kit. We're going to insert it into the top set here. We want to make sure it's the top set. This will be the one closest to the wire and then insert it into our fuse box. We can now test our system out and make sure everything's working properly. We can now plug in our connector and test it out. You can either plus it into your trailer or to a tester like the one we have here. If you need a tester, you can pick one up here at etrailer.com. You want to keep in mind that the lift gate does need to be closed in order for your circuits to work properly. You want to make sure that you have your left turn signal, right turn signal, tail lamps, and brake lamps and with them working properly, we can clean up our wiring at the back and reinstall our panels. Okay, now with all of our panels installed, we're all set.Now if you're wondering where in the world's the wiring we just did, well, I went ahead and took our four pole and tucked it up behind our panel here and this is where it's gonna store when not in use. So you simply just pop that out and that completes our installation of Tekonsha's heavy duty ModuLite vehicle wiring harness for your 2014 Audi Q7.

After one year of use, my "Tow Ready" is working fine. The trailer lights are bright and the Tow Ready unit has not affected my Sprinter van's current monitored rear light wiring. My only wish is that the turn signal and brake lights were two different bulbs and not combined into one. (I like yellow turn signals on my trailers with separate red brake lights.) With this Tow Ready unit, the brake light flashes on and off when the turn signal is on. Other than that, its perfect. Todd from Wisconsin. 248395

After a lot of head scratching, looking for shorts, internet searches, and checks with my meter, I finally figured out that my camper tail and marker lights were dim because of low voltage. My 2000 Ford Econoline Van didn't have the trailer towing package. So, Ford ran the thinnest wiring to the tail lights which, of course, couldn't carry the voltage necessary to the camper. After another search on the internet, I came across your wonderful site. You had exactly what I needed to solve my problem. The videos and descriptions on your website convinced me of the product I needed. The Q&A sections are awesome as well! The only negative on the product was the wiring to the right turn/brake light wasn't long enough for my van, but that was an easy fix with some solder and another length of wire. I also ordered the ModuLite Installation Wiring Kit, Item # 118151 to run from the Modulite module to the battery. Twenty feet of wire wasn't enough to get to the battery through the interior of my van, but did get me to the front of the engine compartment. Again, hardly a problem as I had a length of 12 gauge braided wire to complete the lateral run across to the battery. The Valterra Electrical Cable Hatch for RVs - 4-9/16" Diameter - White Item # A10-2137VP was a perfect drop-in fit on my '92 Jayco. Your website is great and I will recommend you to anyone that needs parts or advice for their trailering and camping needs! Fast, accurate shipping, expert advice in the form of videos, descriptions, and Q&A, phone advice (if you need it), along with a great selection make ETrailer the BEST. THANKS! 523092

First, as to the product: As others have commented, the lack of installation instructions was a little disconcerting. George helped me find the directions online, and everything went well from there. The installation took me about 1 1/2 hours, and I don't work fast. This was a replacement for an older, cheaper Hopkins converter. That one had developed the habit of blinking both turn signals anytime the brake lights were also on. The Tekonsha fixed that, and, as a bonus the brake and turn lights are brighter now. Turning to customer service, in most things etrailer is great. I ordered with two day shipping, and the product was shipped immediately and came via UPS in two days. George was very reponsive to my request for directions emailing a response in an hour. The one disappointing thing was when I called the number after "Call to talk to a product expert", not only did I not get a product expert, the CSR didn't really comprehend what I was asking about. However, she got Bill to call me back, and he answered my questions competently. 430250


Comments
Pretty good, but not perfect. After a few months use, I started noticing the same problem I had with the Hopkins - the off-side lights blinking alternately with the on-side. But faintly. I dont think its enough to be a safety problem, but a little discouraging nevertheless.

I have a 2012 VW Golf TDI. It has very strange wiring, but does work with this Modulite (119190). The issue is that my Golf has a 2 wire setup, but it is the running and brake lights that share bulbs, not the turn signals (it is possible to pick up individual signals for the running lights from the car's license plate light and to use the center brake light...but it's hard to get to them). But, I was surprised in my testing that this converter works fine like this. I used the red wire for picking up the combined brake/running signal, and left the brown wire unconnected (however, I will go back and ground it). Turn signals hook up normally. 79547

This Circuit Protected wiring harness is essential for use on any BMW that has not been factory pre-wired for a trailer. These cars are prone to electronic board failure ($4000.) if a standard wiring harness is used...do not do it - it will void the car warranty. This product is the only one I found that is suitable. Beware that there are others on the marketplace that are similar but do not provide adequate protection to the vehicle wiring and circuits. U-Haul has a very good one that actually has an LED feature on the 4-Flat plug that makes it simple to verify that each of the wires are connected properly and functioning however theirs does NOT provide protection when both brake and tail lights share wires. This review may not make sense to some readers but your BMW dealer and any knowledgable trailer hitch installer/supplier will know exactly the importance of using this exact product. Great product, very fair price and very quick delivery from etrailer. 52720

The product was delivered overnight just as requested. It is so difficult to find a company nowadays who not only will have the products in stock but that will also ship them as you have requested. Even though I requested overnight shipping on the product, I was honestly not expecting it to arrive until a couple of days later. I was presently surprised when it arrived the next day. 33611

Mike, I have a BMW X-5 as well but I am not sure which wires to connect to. It appears they use the same wire for the brake as the tail light. Cant figure out the reverse light either? Can you help me?

I purchased this product to convert the 3 way tail light system in my Freightliner FLD 120 truck/tractor to use for my agriculture trailers that use a 2 way light system. I have several trailers I use and each of them have a lot of lights, so I needed a powered converter. I had tried using a non-powered converter first, and the hazard lights would not flash since the tail lights exceeded the maximum 2.1 amps of the converter. This product has a maximum limit of 4.2 amps and meets the amperage requirements for the conversion. I have converted my Freightliner to haul gooseneck style trailers which come wired with electric brakes and a 7 pin RV connector. I installed the converter up in the dash area of the truck connecting to the wires located there. The RV connector is not compatible with the 7 pin commercial truck wiring so you have to make some wiring changes in addition to the conversion from 3 way to 2 way. But as to this product, it works great. I needed my converter shipped overnight because of a time factor on a must have basis, and eTrailer did just what was needed and the product arrived as promised. Also eTrailer had a tech contact me personnally to answer some questions about another product I had purchased from them over 5 years ago and was most helpful on that issue. As far as my opinions go, this company is great to do business with and I would highly recommend them for your trailer and wiring needs. They know their product, believe in customer satisfaction and customer service, and can solve your trailering problems and issues. 29409

It draws the actual power to operate the trailer lights not through the car's internal wiring but through a separate 12V power wire you connect to the battery. Installation is mostly a plug-in, except for that one power wire that will run from the converter unit...

  • Tail Light Converter to Combine Separate Stop and Turn Lights for Trailer
    In most trailer wiring the stop and turn light signals are combined into one circuit for each side of the trailer. 4-pole wiring uses a yellow wire for the combined left-hand stop/turn signal and a green wire for the right side. 7-way wiring also combines these light functions. You can refer to the linked article on trailer wiring. If you are looking to connect a motorcycle's separate stop and turn lights to a trailer whose lighting is combined you can use Roadmaster part # RM-732. This...

  • Troubleshooting the Brake Light Not Working on a Trailer Hooked up to a 2016 Toyota Land Cruiser
    The problem that you are facing is that your trailer is running the right turn/stop on one wire, and the left turn/stop on a separate wire; otherwise known as a 2-wire system. Your 2016 Toyota Land Cruiser has a 3-wire system where the left turn, right turn, and stop wiring is run on separate wires. What you will need to do is use the Tekonsha Upgraded Heavy Duty ModuLite Circuit Protected Vehicle Wiring Harness # 119190. This wiring harness will combine your stop signal with your turn...

  • Is Taillight System of 2005 Dodge Ram 3500 a 2 Wire or a 3 Wire
    Your 2005 Dodge Ram has a 3 wire system. To install the 119190, the green converter wire would tap into the right turn signal circuit, the yellow into the left turn circuit, the brown into the running light circuit , the white would ground and the red wire would connect to a brake lamp circuit. If you're wanting a hardwire kit, I'd go with the # 119190KIT, which includes the kit for running the power wire to the vehicle battery and the circuit tester which aren't included with the # 119190. Going...

  • Is There a Way to Reset the Curt Converter Box on Vehicle Wiring Harness on 2003 BMW 325i Wagon
    It does sound like your converter box may be defective. Unfortunately, there is no way to reset the converter. I recommend trying to relocate the ground of the converter to see if this provides a solution to your problem. Grounding issues can show themselves in strange ways. If relocating the ground doesn't fix your issue, I recommend replacing the wiring harness. For European cars like your BMW 325i Wagon, we've found we have the best success with the Tekonsha Upgraded Circuit Protected...

  • Troubleshooting 7-Way Install on 2018 Ford Explorer
    Though the Vehicle Wiring Harness with 4 Pole Trailer Connector # 119190 is a universal hardwire kit, you will not need it with your 2018 Ford Explorer if you already have the T-One Vehicle Wiring Harness with 7-Way Trailer Connector # 118272. The problem almost certainly is the 7-way connector was wired incorrectly after you plugged it into your Explorer, or that you have not fully seated the wires into the connector. If you take a look at the cut out of the linked installation instructions...

    This Upgraded Modulite Circuit Protected Vehicle Wiring Harness, part # 119190, you referenced features circuit protection that will safeguard your 2006 Dodge Ram from getting damaged due to mis-wires and electrical shorts.

  • Trailer Light Wiring Harness Option for a BMw I3
    Generally when there is not an option available here and from manufacturers, there just isn't sufficient demand to justify creating a plug-in solution since vehicles like the i3 aren't as widely used to tow. A universal option like the ModuLite Circuit Protected Vehicle Wiring Harness with 4 Pole Trailer Connector # 119190 can be a solution however it will require some custom installation including splicing wires, etc. I have included the review and installation videos for this part...

  • Why Would 4-Way on 2011 Kia Sedona Have Pins Hot All the Time
    What you described sounds like a shorted out converter box. Nearly every time one of the boxes fails the symptoms you described are what happens. Also, the Curt harnesses are notorious for shorting out easier than the Tekonsha. I would recommend you go with the part # 118410 after seeing if you can find the short that's on your trailer's wiring. Now if your trailer does not have brakes all you would need is the part # 37185 as an adapter to convert the 4-way to a 7-way. If you do...

  • How to Install a Universal Trailer Tail Light Wiring Harness on a 2006 Dodge Ram 1500
    Your 2006 Dodge Ram 1500 actually has the separate tail light wiring system, meaning the turn signals and the brake lights run on separate wires. The tow package wiring will have the combined-wire setup, but if you are installing the Tow Ready Universal Wiring harness, # 119190, to bypass the factory tow package wiring, then you will want to follow the instructions for the separate (3-wire) system installation. This means the Yellow wire goes to the driver's side turn signal, Green...

  • Recommendations for Installing a 7-Way and Brake Controller in a 2006 Dodge Ram
    If your 7-pin connector looks like the picture I attached and you have tested the circuits of the plug and they are functional then I would recommend you use a Hopkins Endurance Quick-Install 7-Way Trailer Connector # HM42190 for a trailer wiring harness. For a circuit tester you could use our Circuit Tester part # 3808 or something similar. You will probably need a brake controller too, for that I recommend you get a Tekonsha P2 Brake Controller and Vehicle Harness # 90885 and # 3020-P....

  • Cost Effective Solution for Fixing Trailer Wiring Harness on a 2006 Dodge Ram 1500
    What I would do in your situation is install the # 119190 and not mess with paying a ridiculous amount of money to have your TIPM replaced or reflashed. This harness will bypass all that nonsense and will give you a 4-way harness. If you are looking to use a 7-way trailer harness what you could do is cut the 4-way off of the # 119190, and then cut the harness of your factory 7-way and wire up the wires of the 4-way to the correct pin locations on your 7-way.

  • Recommendation for a Trailer Wiring Harness for a Victory Vision Motorcycle
    I would recommend using the Upgraded Modulite Circuit Protected Vehicle Wiring Harness with 4 Pole Trailer Connector, item # 119190KIT, which is the wiring harness that you mentioned. The 119190KIT includes the all of the wiring needed and a circuit tester to help determine the wires to splice into for the tail light functions. The # 119190 wiring harness is a powered harness that draws only about 5 milliamps from the vehicles tail light circuits and provides power to the towed trailer...

  • Trailer Wiring Harness for 2013 VW Tiguan
    The # 119190KIT would work great on your Tiguan. There is no difference between the 119190KIT and the 119191KIT, they are both the same part. Tow Ready sells the part two ways, as # 119190, which doesn't include the wire to run to the battery or the inline fuse, or as # 119191 which includes the wire and the fuse. We sell it as 119190 without the wire/fuse and 119190KIT with the wire/fuse. I've linked to the install instructions, but they're pretty general in nature. Use a circuit tester...

  • Can a Modulite Trailer Wiring Harness be Installed Under the Hood of a Vehicle
    Technically, you could install the Heavy Duty Modulite # 119190 anywhere that it will fit, including under the hood. But since it is meant to wire into the vehicle tail light wiring for trailer lights the easiest place to install it would be the rear of the vehicle. Otherwise you are running all of the tail light wires and 4-Way to the back of the vehicle which would require a lot of extra wire.

  • Wiring a 2007 VW Eos 3.2 with Multiplexed Wiring for Towing a Trailer
    The 2007 Volkswagen Eos has a Multiplexed wiring system that requires wiring the Upgraded Heavy Duty Modulite Circuit Protected Vehicle Wiring Harness, item # 119190, for a trailer connector. There are 3 ways of wiring depending on how your vehicle is wired from the factory. In the instructions, at step 9 (see link), it explains that you may have a two wire system that requires the red stop wire to be grounded along with the white wire. If you have the 3 wire system (most likely) with amber...

  • Trailer Wiring for 2005 Dodge Sprinter
    A new harness may be the solution, but you may not need to spend money to fix the problem of your turn signals not working with the trailer wiring on your 2005 Dodge Sprinter; what you can do first is a bit of troubleshooting to find out. In order to determine the specific problem you will need to use a circuit tester such as # 40376 to test the connector on your Sprinter after disconnecting it from your trailer. Check the wiring going into your harness from your tail lights to see if...

  • Can Power Wire for Trailer Wiring Harness be Connected to 12 Volt Outlet on 2013 Volkswagen Tiguan
    No. The issue is that wiring harnesses # 119190 or # 119190KIT are tested and rated for a connection to the battery only. Installing them using any other method could cause undesired operation. Also, if connected to a 12 volt outlet, you will lose that level of circuit protection between your 2013 Volkswagen Tiguan and the trailer. Routing the wire is just time-consuming but not really difficult. I have included a link to a help article with tips on routing the power wire for you.

  • Installing Trailer Wiring Harness Part #119190 on a 2013 VW Tiguan
    Some vehicles combine stop and tail light functions onto 1 circuit and then also have an additional tail light function wire that is independent of the stop (such as your 2013 VW Tiguan). These vehicles will require that you attach the trailer light power module red “stop” wire to the same combined circuit on the vehicle and then attach the brown “tail light” circuit to the independent circuit on the vehicle.

    If the 4-Way flat came on the truck from the Toyota factory, there would be no need to buy an Upgraded HD Modulite harness like part # 119190. The truck would have all the necessary electrical components in place. You would just need a 4-Way to 5-Way adapter like part # 20036. The blue wire is then connected to the reverse light wire on the truck if the trailer uses the blue wire for reverse lights. Occasionally the blue wire can be used for trailer brakes on a trailer.
