Video Transcript for K Source Custom Towing Mirrors KS70103-04T Review

Today we'll be reviewing part number KS70103-04T. These are the K-Source Custom Extendable Towing Mirrors. Both the driver and passenger side mirrors are included. To see if these are going to fit your particular year, make, and model, you can refer to the vehicle list at the bottom of the product page. The mirrors replace the factory side view mirrors on your vehicle. They do offer a telescoping function that makes this perfect for those perfect for those who frequently tow a trailer, make it easier to park, change lanes, and pass.

All you got to do is pull the mirrors away from your truck to extend the lines of sight by up to 3 and 3/4 of an inch. It's really going to make it easy to see around the side of your trailer. When you're done you can just push the mirrors back in. When you're not towing or when you need to park, it makes it a little bit easier. That's going to eliminate the need for custom towing mirrors or snap-on mirrors as well as-strap on mirrors that you constantly have to install and uninstall.Each mirror is going to feature an amber turn-signal light that's built into the side of each mirror.

If I turn those there, you can see those. That's these right here. We have the spotter mirrors on the bottom that help to further reduce blind spots. The main mirrors have power adjustments and the spotter mirrors are going to be manually adjustable simply by just pressing in on the corners or the side that you need to get the angle that going to best suit your application.These mirrors are actually designed to fold up against the vehicle for parking or fitting into tight spaces. The custom design is going to provide a perfect, secure fit for your vehicle.

They are going to use the factory connections for electric, turn signal, and heat functions. You can see that there. It also has the same footprint and uses the same mounting points as the factory mirrors. Again, the driver's side and passenger's side mirrors are included.We're going to go over a few dimensions so we're just going to be using 1 mirror because the dimensions are going to be the same for each one. Overall length when fully retracted is going to measure about 20 inches.

When it's fully extended, that's going to increase to 23 and 3/4 of an inch giving us that 3 and 3/4 of an inch extension. The mirror face overall width is going to give us a measurement of right around . We're going from the end of housing to the end of the housing. It's measure about 9 inches. Overall length, measuring both mirrors, is going to be about 10 inches tall. The main mirror is going to be about 7 inches in height and the lower mirror is going to be about 2 and a 1/2 inches.Please keep in mind that you cannot upgrade to a power mirror with a heated face and turn signal if your OEM mirror is not already equipped with those features.That's going to do it for today's review part number KS70103-04T. These are the K-Source Custom Extendable Towing Mirrors. .

Installed these mirrors on my 2015 Sequoia SR5 4x4. Installation is fairly easy. Door panels come off easy but are more difficult to put back on, you have to be sure the plastic snaps or keepers are aligned before popping it back in place. The mirrors themselves are decent quality but do not have the fit of the factory mirrors. I noticed a gap of approx. 3/16" at the very top of the mirror mounting bracket, it should be flush to the car body. The turn signal lights on the side of the mirror do not work with my vehicle, I read many reviews from others that said their signal lights worked despite not having that feature originally. So be prepared if they don't work. Also be sure to tighten the mounting nuts on the new mirrors, mine were not tightened down. The mirrors look good and perform the function they were designed for. 552346

Mirrors look great and install was a breeze. It took longer to get door panel off than it did to swap out mirrors. My only complaint is that the passenger side mirror has a huge increase in how close objects appear to be to the truck compared to OEM mirror, so there is an adjustment period to get use to the mirror. 511237

Product was relatively easy to install if you search for and follow the YouTube video. Have not had a chance to hook up my travel Trailer yet but it looks like It will be no sweat seeing all around it with theses mirrors. Service delivery time was right on the money. Thank you for the prompt delivery. Julie M at e-trailer was great at getting my shipment to me as promised thanks Julie. 106631

Mirrors were delivered early. I was impressed. They were carefully packaged and look great. It took about 10 minutes to install each side. Plus the turn signal works on the mirrors also. I would recommend them to anyone that wants to up grade 415463

When i spoke with Adam about the mirrors he promised two day shipping. I received the mirrors next day. (I am only 2 hours away from there location so this may not happen for everybody) The mirrors showed up well packed and in perfect condition. Yes the blinkers work on the new mirrors and i did not have that option on the old ones. I love the fact you can call them on the phone speak to a real person, to make sure you are getting what you need. Will be telling all my friends and family about Etrailer and ordering more parts in the future. Thank you. 511074

Mirrors fit like they should. Installation was about an 45 min. Nice having running lights and turn signals on the mirrors. I have not had towing mirrors on any truck in the past so it may be the nature of the beast, but there is a little vibration at cruising speed in the mirrors. Not enough to be concerned. Just enough to notice. I have a 2011 Tundra. Overall very happy with the mirrors. 415131

This was a fairly easy job, although ripping off the door panels was a little unnerving. My truck is a 2011 Tundra and had electric/heated mirrors. I was pleasantly surprised that the built in turn signal and running lights now work! Everything was plug and play! Love them! 321740

The mirrors were very easy to install. They look great on the truck too! The only problem we had was dropping one of the bolts in the door panel. The clarity of the mirrors are not as sharp as the original Toyota mirrors but will work fine. Just be sure to note on website: "Be Careful - Don't Drop Bolts in Door Panel" it was a real pain to get the bolt out. We installed the first mirror in about 15 minutes. However the second mirror took a little longer because we messed up and dropped the bolt! 71537

Installed these on a 2016 Tundra SR5 to replace the factory mirrors. Installation took about 90 minutes total; I took my time; working slow and smooth...which actually makes the job go fast :-) Some tips from my work: 1) Several videos on YouTube re: door panel removal; A1Auto had the best 5 minute video on this IMHO Also several stereo speak install videos that cover door panel replacement. 2) Take the extra minute or two and remove the door lock / window control units and to disconnect the lock cables...it's very easy, and the door panel is light...that allows for complete removal of the panel and not leaving it hanging by cables and wires. 3) I used a deep socket, 1/4 drive, 10mm to remove the locking nuts on the stock mirrors; when the nut was ~ 2 turns from being removed, I switched to a 3/8 drive, 10mm with a magnet extension to finish removing the nut...you really do not want any of the nuts dropping into the inside of your door. Really nice to have larger mirrors on the truck for towing; took it out for a drive; no vibrations; and lots of visibility on both side of the vehicle. 508827

The mirrors arrived well packaged, so no damage. No instructions were provided, but there are a couple installation videos available on YouTube. It took a little over a half hour for both mirrors. Very simple. A few tips: * To avoid having the mirror nuts accidentally fall into the door, I used a napkin stuffed into the holes. * Squeeze the mirror connector to disconnect * After the old mirrors are removed, a black grommet is left behind. Rather than try to match it on the new mirror, I just removed it as well. It wasn't needed. * To reinstall the door panel, make sure to place it over the window lip first, then push down. The grommets then line up perfectly. Best part: the old mirrors were power + heating. The new mirrors also had turn signals and marker lights, and they worked! 91019

The mirrors were delivered in 5 days, and look sharp! Installation was a breeze after watching YouTube videos. I am not a mechanic, and wouldn't have tackled installation had it not been for the videos. The only disappointment was finding out that the mirrors must be folded in manually (like to go through a car wash or other tight space). The original mirrors folded at the push of a button. 187464

The Tundra towing mirrors were installed in about 1/2 Hr. each. There were no problems, all the electrical functions worked extremely well. I am well pleased with the results. Anyone towing a travel trailer will be much safer using these mirrors. I went out for a drive after the installation, and at 70 MPH there was not problems. After extending to their fullest length for towing there was a little vibration in the mirror, but not enough to be a problem. But, i do not tow at 70 MPH anyway, at slower speeds there is not problem, even extended. 488280

I put these on a 2017 Toyota Tundra. I pull a 29 ft travel trailer and couldn't see with the stock mirrors. The mirrors were easy to install. Took 30 mins all together. Was able to put them on by myself. Just like the Description said. The mirrors were packaged nicely also. Plug them in and good to go. Everything works like from factory. 376042

So far so good; had my son put them on for me and he a Toyota Tech. First one took a half hour drop a nt in the door could not find it; then discovered the new one had nuts on them; second one done in 20 minutes. All this was done at nite with a flash lite. A instruction sheet would had been nice; but that's what the Kid is for. 459081

Mirrors went on with no problem at all and took me about 25 minutes per mirror (I took my time to make sure I did it right). Like others have mentioned, original mirrors did not have turn signals or running lights, but the new ones do and work just fine. Watch a couple YouTube videos (type in Replacing a Toyota Tundra Mirror) and you'll see how easy it is to replace the mirrors, but do watch the videos because there are absolutely no instructions or paperwork that comes with these mirrors. And as others have mentioned, you really should put a piece of tape at the bottom of each of the three holes to prevent the chance of one of the three nuts holding each mirror in place from dropping down into the door frame. If one drops down there, good luck in getting it out!!! Overall, very happy with the mirrors. Look like OEM Toyota mirrors and hopefully time will prove them to be of similar quality to Toyota OEM parts. 149329

What a great upgrade for my 2015 Toyota Tundra SR5! Perfect fit. Only took about 15 minutes per mirror to replace them. I didn't have blinkers or clearance lights on my stock mirrors, but these mirrors plugged right in and now I do. I do confess that they are taking me some time to get used to, but I can now see where my tire hits the ground and still have full view of the side of my truck. I can't wait to use them to pull my new travel trailer. I will no longer be a nervous wreck, constantly adjusting my mirrors so that I don't run into something. The biggest problem I see is that I can no longer park in my parking lot at work without getting out of my truck to fold the mirrors in. I'm not certain, but I would guess they add about 4-5 inches width on each side of the truck. I'm ok with that, because these things are a necessity when towing a big trailer. Thanks Etrailer! 279928

Received the mirrors in less than 3 days. checked out the video on utube and on Saturday took me about 30 mins to change out both mirrors. Mirrors look great and perform outstandingly. The lights and turn signals work even though the old mirrors did not have that. The remote positioning works and I would say the defrosters will also (still in the 80's) I have included pictures. Now I can see the back of my camper and should have an easier time backing. Thanks 146365

The mirrors arrived well packaged and with no instructions. Following easily found YouTube vid, installation was easy taking around 15 minutes per mirror. The mirrors are good quality. On my 2010 Tundra the signal, heat, and adjust features all function fine though my OEM mirrors did not have the signal feature. The driver's side mirror produces a whistle when the vehicle is moving faster than around 45 mph. I hope to fix that with a piece of duct tape... without the whistle they'd get that fifth star from me. 93234

Uh, a Google search for replace tundra mirror produces two videos among the top ten search results. Both videos where helpful. The mirror replacement is straight forward. Pulling the door interior off takes a bit of force. I hadnt done it before so didnt know quite how hard to pull. Start at the bottom as in the video, lift up and outward. There are still some wires attached so have something to set it on, or someone to hold it.

We purchased these towing mirrors to replace the original factory mirrors on our 2008 Toyota Sequoia SR5. The towing mirrors fit perfectly and have made towing much easier. We had our local Toyota dealer install them which cost less than $100. As others had mentioned none of the features of the mirrors which weren't supported by the factory mirrors worked (heat and turn signals) which was expected, but the power mirror did work, since it also worked with the factory mirrors. Free shipping and fast delivery made everything quick as easy. 143207

Mirrors came undamaged. The first mirror took me about an hour to put on and that's because I had trouble putting my door back on. There's a little metal ledge that the door sits back onto that I couldn't seem to figure out. I got the snaps lined back up, but because I didn't hook the ledge over it caused the door to bulge and it wouldn't sit right. Overall there is no vibration in the mirrors and they work great! I added a video on youtube for those who want to see. At the end of the video I include a quick freeway test ride. The mirrors DO NOT whistle as I have seen on other towing mirror reviews. The only things is they add some road noise. That's expected as they are bigger mirrors....so they catch the wind easier. It's not noticable when your radio is on. Here is the video of my install....I apologize for the bad camara angle....it was on my head and there are some parts where I'm pointing to something out of view. 451515

Even if your 2012 Toyota Tundra does not have turn signal mirrors, you can still use the K-Source mirrors, # KS70131-32T or # KS70103-04T. The other option are slip-on towing mirrors that fit on the factory mirrors, # CM11300. If your mirrors look like the one in the picture I have provided, these slip-on mirrors will fit.

  • How to Determine if Towing Mirror Turn Signals will Work on a 2010 Toyota Tundra CrewMax SR5 4x4 V8
  • We have two towing mirror options for your 2010 Toyota Tundra, I provided links to both for you. The turn signal feature in these mirrors will only work if the connection on your Tundra is factory wired with a turn signal circuit. You can test the connector on your mirror before ordering to be sure that the turn signal function is present. To test the connection, use a circuit tester like part # 40376. Attach the alligator clip to a good ground, unplug the factory mirror and probe the...

  • Towing Mirrors for a 2016 Toyota Tundra that Retain the Factory Blind Spot Detection System
  • I do have towing mirror options that will allow you to retain the factory blind spot detection system on your 2016 Toyota Tundra but the K-Source Custom Extendable Towing Mirrors part # KS70103-04T will not. Unfortunately, none of our replacement towing mirror options retain the factory blind spot detection system. Therefore, the only option I have for you is a clip-on towing mirror like the K-Source Universal Towing Mirrors part # KS3891-2. These are one of the only towing mirror options...

  • Wiring K-Source Custom Extendable Towing Mirrors w/ Turn Signals # KS70103-04T on Toyota Tundra SLT
  • If your OEM mirrors had both the heat and turn signals functions, then your 2008 Toyota Tundra SLT is already wired for those functions. To check whether your truck is pre-wired for the turn signal function use a circuit tester, such as part # 40376, to test the connector pin for each mirror. If you do not have the turn signal function at the connector, then in order to have that functionality with the # KS70103-04T on your 2008 Tundra, you would have to manually re-wire your turn signals,...

  • Towing Mirrors for a 2016 Toyota Tundra Limited
  • For your 2016 Toyota Tundra Limited you could use replacement mirrors # KS70103-04T but the slip-on mirrors are not designed to fit Limited or Platinum models. Another option is to use a universal mirror set such as # KS3990. I have linked video reviews of both mirror sets for you.

  • Recommended Towing Mirror Options for 2016 Toyota Tundra
  • If you prefer the best permanent towing mirror solution we also offer custom-fit extendable towing mirrors with power and heat functions like your OEM mirrors. K-Source offers the mirror set # KS70103-04T which include turn signals. If your OEM mirrors have these same functions (power, heat and turn signals) then those functions will remain active with these K-Source mirrors installed. Please note you cannot add new functions just by changing the mirrors themselves; the vehicle has to already...

They extend manually and can fold flat manually for parking.

  • Do the K-Source Extendable Towing Mirror Have the Blind Spot Detection System Toyota Tundra
  • I spoke to my contact at K-Source and they informed me that the K-Source Custom Extendable Towing Mirror part # KS70104T does not incorporate the use of the factory blind spot detection system. They will still work for you and retain all other factory features but you will lose the blind spot detection system. For a pair of these side mirrors, you will want part # KS70103-04T. We also have them available in chrome using part # KS70131-32T. Unfortunately, the K-Source mirrors are the...

  • 2018 Toyota Tundra Blind Spot Monitor Towing Mirror Compatibility
  • From what I've found online you can disable the blind spot monitor with buttons on your dash. They will reset each time to start your vehicle, so you would have to do it each time you start your vehicle which would be quite the hassle when you stop for gas to remove your tow mirrors like # KS3990 just to start your vehicle and hit the button so you don't get the light. If you want to mount towing mirrors like the K-Source Custom Extendable Towing Mirrors - Electric/Heat w Turn Signal...

  • Toyota Tundra Electric and Heated Towing Mirror
  • The K Source custom towing mirrors # KIS70103-04T will actually use the factory connections for electric, turn signal and heat functions. Please note that your current electric mirrors must have the turn signal and heat functions in order for the new K Source mirror turn signal and heat functions to work. There is more to it than just the wiring harness, including but not limited to the proper fuses and relays on your Toyota Tundra. Also, some vehicles will not have the wiring for all...

  • Recommended K-Source Custom Heated Electric Towing Mirrors for 2015 Toyota Tundra
  • I checked with my technical contact at K-Source, maker of the Custom Extendable Heated/Electric Towing Mirror Set # KS70103-04T, and she confirmed that they have recently verified the fit of these mirrors on the 2015 model year Tundra. Please note your Tundra must already have the heat and power features in its OEM mirrors. Those functions cannot be added to a vehicle that does not have them by adding an aftermarket product; the wiring to support those functions must already be in place...

  • Is There a Difference Between K-Source Towing Mirrors for 2016 Toyota Tundra?
  • The only difference between the towing mirrors is that K-Source Custom Extendable Towing Mirror # KS70104T is for the driver's side of a 2016 Toyota Tundra while # KS70103T is for the passenger's side and # KS70103-04T allows you to purchase both at the same time as opposed to individually.

  • Can Electric, Heated Towing Mirrors w/Turn Signals be Used if Factory Mirrors Do Not these Functions
  • The K-Source towing mirrors # KS70103-04T will fit your 2010 Toyota Tundra. Since your truck does not have heat or turn signals, those features will not work on the mirrors but the electric operation will still work. Another option is to go with some slip-on mirrors # CM11300. These are ideal for infrequent towing and are more cost effective than replacement mirrors.

  • Do K-Source Custom Extendable Towing Mirrors for the 2012 Toyota Tundra Fold
  • The K-Source Custom Extendable Towing Mirrors, # KS70103-04T, can manually fold but they do not have a power folding feature which is an option on some factory Tundras. These mirrors have turn signals, electric mirror faces, and heat features but these features will only work if the factory mirrors on the truck had these features. Any other feature will be lost.

  • K-Source # KS70103-04T Replacement Towing Mirrors for 2014 Toyota Tundra W/ Power Heated Mirrors
  • The K-Source replacement towing mirrors you referenced, part # KS70103-04T are indeed compatible with your 2014 Tundra. Since your existing mirrors feature power adjust and heat, you'll retain those functions. However, since your current mirrors don't have the turn signal function, the turn signals on the new mirrors would be inactive.

  • Will the K-Source Custom Towing Mirrors work on a 2012 Toyota Tundra with Power and Heat Functions
  • The K-Source Custom Extendable Towing Mirrors # KS70103-04T that you referenced can be used on Tundras like your 2012 Toyota Tundra that has heated mirrors but no turn signals. Everything will hook up and function like your current mirrors, except you will not gain the turn signal feature.

  • Fit of K-Source Extendable Towing Mirrors # KS70103-04T on 2013 Toyota Tundra
  • According to my contact at K-Source, the # KS70103-04T mirrors you referred to do indeed carry over to the 2013 Tundra. Even though your current mirrors do not have the turn-signal feature, you can still use these mirrors. Because the OEM mirrors did not have the feature, the turn signals on the K-Source mirrors will NOT operate. The heat and power adjustment features will be retained. Keep in mind that the smaller spotter mirrors are NOT electrically adjustable.

  • Can Turn Signal Function be Added to 2012 Toyota Tundra K-Source Custom Towing Mirrors
  • K-Source towing mirror # KS70104T, and the set, # KS70103-04T, will retain the heat and power operation functions of the stock mirrors on your 2012 Toyota Tundra but you would not gain the turn signal function since the stock mirrors do not have that feature. The only way that you could get it to work for sure would be to tap into a turn signal circuit on the truck. But it theoretically could be done. I have linked a video review of the mirror set for you.

  • Objects Appear Farther Away Than They Are Using The Passenger Side K-Source Mirror #KS70103-04T
  • I reached out to my contact at K-Source to confirm that the K-Source Custom Extendable Towing Mirrors w/ Turn Signals - Electric, Heated - Pair # KS70103-04T does have the slightly convex mirror on the passenger side that makes objects appear farther away. This is why many factory mirrors have "objects in mirror are closer than they appear" printed on that passenger side mirror. These mirrors will work much like factory vehicle mirrors, just with the extended/expanded view.
