Video Transcript for How to Install: Tekonsha Voyager Trailer Brake Controller on your 2022 Chevrolet Colorado

Hi there, Colorado owners. Then your 2022 Chevrolet Colorado we're gonna be taking a look at and showing you how to install Tekonsha's Voyager proportional Brake Controller. This is a proportional brake controller so the inertia sensor inside will detect vehicle movement. So if you ever slam on the brake show your body like kind of slams forward the inertia sensor detects that, and it knows that it's your vehicle is slowing down based on that. And it uses that along with your adjustment controls to give you the best breaking performance at the back. This is a very simple brake controller beyond the adjustment for a level and the output control.

On the other side, you just have your manual slide which can be used for if your trailer starts to sway or anything you kind of hit the manual slide to apply the brakes on your trailer and to help straighten you back out and get rid of that sway. And that's kind of it. This brake controller is just very simple gives you that fully proportional break output. And it does work with trailers up to four axles. We'll begin our installation here on the driver's side.

We're right down here at the kick panel. There's the parking brake pedal. I'm gonna go ahead and push it down just to help make things a little bit easier to see. And this panel here we're gonna be removing to remove the panel. You're just simply gonna pull up on it.

So your fingers should be able to grip underneath of it here. And kind of at this middle point here we're gonna pull up and we're gonna be working our way towards the back of the panel, pulling up on it. There we go. Once you get the back released and get towards the front here, you're gonna kind of pivot it like this and pull away from the wall here. You got a clip right there and that'll pop out of there.

And then we can just set this panel aside behind our panel. You're gonna find your factory break controller wiring and it's just taped right here cut the tape and that'll expose our wires there. We've got four wires here and this will hook into our brake controller. We're gonna use a harness. It has four wires on it as well. So everything will just match right up to what we've got right here. So we can make our connections. Now for demonstration purposes today we're not gonna be fully mounting it. We're gonna use some hook fasteners to secure it and we're not gonna be opening up the little hardware pack that it comes with. So that way we can repackage that. So we're gonna strip back each one of these wires and hook them up. I like to do it one at a time just because the red wire here, is your hot wire. So once you strip it back, that wire's live there. So I kinda like to get that hooked up right away to prevent it being stripped and potentially shorting up. So we're gonna go ahead and just take our start with our red wire here. It has a green Stripe on it. That's our main power wire. So we're just gonna strip it back. You may wanna trim a little bit off cause it's got those little ends on it there. So we'll probably trim a little bit of this off and then strip it, just to make it easier to strip with that material that it had on there. So give it a little twist makes it slide into the butt connectors more easily. We'll slide our butt connector on there and then we'll attach our wire to it. We can now hook this up to the appropriate wire here on our new harness. That's gonna be the black wire on our harness to power up our module, our brake controller. So we'll slide that in the other end of our butt connector and make our connection. So now that we've got that connected there we're just going to repeat that process to connect the rest of our wires. We'll be hooking the blue wire in our harness to the blue wire here on the vehicle. That's the output from the brake controller. So that'll send it down this wire to the back. The uh, white wire here on our harness is ground. And that'll actually hook to the black wire here on our vehicle. That'll be our ground. And then the red wire here, on our harness is for the brake signal input to the brake controller. So that's coming from your brake pedal here. So it lets the brake controller know when you're pressing the brake pedal and that'll connect to the white wire with the small blue Stripe on it there. So I'm gonna strip each one of these back and then make those connections and then you'll see those here. All right. So now that we've got all of our connections made here I'm gonna reinstall this panel and kind of tuck my wiring out the top of it when I reinstall it and we're gonna be mounting our brake controller roughly in this location here, that way it's kind of out of the way our wiring will reach it easily position it just off to the left so we can still access our hood release switch. And that is now fully reinstalled. We still have access to our wiring there to be able to Mount our controller. Now, typically when you mount your controller you're gonna screw the bracket straight into the dash. But again, for demonstration purposes we're gonna be using some hook and loop fasteners just to stick it there. So that way we don't mess up the dash here. That is not really how you wanna leave your brake controller installed 'cause this is an inertia based controller. So it means to detect vehicle movement. So it is important you screw it in place. Now, after we've got it mounted up we'll simply just plug our controller in that'll plug right into that harness. Now this harness doesn't, did not come included with the Voyager controller here but you can buy it kitted that way here at e trailer, to ensure that you get it with your brake controller. But if you just need the brake controller maybe you've already got one of these harnesses, you can buy just the brake controller by itself without the harness kited with it. After you plug in your brake controller you can kind of hide the wiring behind the dash there. And at that point you can see it's powered up. I plugged in the tester here to simulate a trailer. And if we hit our manual slide you should see the gauges activating on our tester there. And we can see we've got output. It's actually pulling ampage and it was operating both or it was operating our brake lights as well. You can see you get a real time display on top of the amount of output that you're putting towards your trailer's brakes based on the L E D light on top. Green being basically like no output going to yellow for a minimal amount, transitioning up to red for maximum. And as you slide the manual slide, you can kind of control how much of that output you're putting up. So once you verify it's working we do need to level this system. It's this very quick calibration. So that way the inertia sensor knows the angle that you've tilted it at to adjust that with your trailer connected and everything hooked up you wanna make sure the knob here on the right side is set to the maximum. So turn it fully clockwise to maximum put it to maximum output. And then the adjustment knob you see here on the left this is your level adjustment. We're gonna turn that one fully counterclockwise. So that's gonna be kind of turning it this direction. We're then gonna press the brake pedal. Our output is red. Red is gonna be the most aggressive setting. We wanna turn our level knob clockwise. Now bringing it back towards us. Once it turns orange, that's kind of your typical setting. That's usually where you're gonna wanna set that level adjustment at to get the typical output. But if for whatever reason you need a little bit more aggressive breaking you can tilt it. You can turn it a little more counterclockwise to get to that darker orange or red to be more aggressive. But you kind of wanna hover around that area of orange between that orange and like lighter red like right when you're getting into the red that'll get you at a nice setting for the inertia sensor to operate properly. And then we can use our maximum control knob here. This is the output from our brake controller. Just properly set that for your trailer. The heavier your trailer is, the higher you're likely gonna need this set. The smaller your trailer is and you can might be able to back it off and turn it down. You'll again, when you adjust that knob when you hit the brakes that will affect the L E D. So I've got, it turned fairly low and you can see it's a very light shade of orange but as I increase that, it becomes more aggressive. So just find the setting that works best for your truck and trailer combination there. And then you're good to go..

etrailer makes the purchase easy. I have always used Tekonsha Voyagers, and on my new truck (2015 Silverado) I also wanted the convenience of having the plug and play wiring harness. etrailer had exactly what I needed and was very easy to find on the website. Installation was flawless and clean thanks to the good hardware supplied. Very excited to put some trailers behind the truck with the stopping power confidence that comes with the Voyager.

Working great! The mandatory leveling process was successful and the unit functions as intended.

by:
The Tekonsha Voyager trailer brake controller works well in my 99 Silverado 1500, which was easy to setup for my trailer. The option to allow for different settings of aggression for the trailer braking has allowed the stopping with different loads to be graceful with the turn of a knob. Decided to install the controller in CD storage with velcro for a nice look. Easy access when in place during use for easy observation and twicking during operation. The wife can assist with the twicking while I am driving. Excellent product!

The Voyager unit has been working flawlessly this past year. Excellent product that keeps on working!

by:
2005 Saturn Relay
Completely plug and play installation and works flawlessly, very happy with this unit. I also ordered the exact harness for my 2005 f150 with tow package. Here are a couple of hints that may be helpful. My installation also required a 30 amp cartridge fuse to be installed in the fuse panel in location #105(electric trailer brakes) under the dash on the passenger side. I also installed a relay in location r05 (trailer tow battery charge) but I don't think this is needed for the controller to function. I still had the original trailer brake kit and it had the additional fuse panel instructions and the relay. The owners manual showed where the 30 amp fuse and relay plugs in. You cannot test this unit until a trailer with brakes is connected, ie the led will not light up until it senses a brake circuit.

The product was easy to install with the help of the F-250 adapter. I followed the direction and the product worked just as it was advertised from etrailer.com. If I had to give the Tekonsha Voyager Trailer Break Controller a star rating from 1-5, I would give it a 4.5.

Received this yesterday and was able to install it today. Instructions were very easy to follow and the only problem I had installing it was contorting myself to install the bracket. Once I got the bracket in place the rest was a piece of cake. Went for a test drive as the instructions suggested and did have to tweak it a little but it's doing exactly what I expect it to do. I'll be hauling a John Deere Tractor and wanted to make sure the brakes on the trailer worked.

The installation was very easy. It helps to have a 90 degree screwdriver to install the
screws on the right side. The screws will install easier if you install them first, remove them
and re-install after the bracket is installed on the vehicle.

Nice controller, compact and good instructions. I cut the plug and hard wired on my application (98 Sierra) Had no issues.
by:
2019 Ford Ranger
Installed on a 2019 Ford Ranger with factory 4 pin connector, no tow package.
To save others time here is what i found out while trying to wire this in. Disconnect the negative battery or you may blow 2 fuses while doing this.
There should be 4 wires under the dash bundled together with heat shrink on them.
They will be Blue, Yellow with Red tracer, White, and Purple with White tracer.
Blue is trailer brakes, Yellow/red is batt+, White is ground, Purple/White is brake light switch.
by:
This was an easy install on my 2019 GMC truck using the appropriate wiring adapter. Instructions for setting up the control were clear. After a few adjustments my trailer brakes worked as they should. Minor adjustments of the controller are needed from time to time, but overall the controller is reliable. Good value.

Tekonsha Voyager Trailer brake controller was purchased to replace the one I installed in 2003, which finally failed after 14 years of service. Everything works great once again on my wife's horse trailer, she is safe once again hauling her horses, and life is good! Fast, efficient service on my order was greatly appreciated.

I pull a small camper with a VW Touareg. The electronics in the T'reg don't play well with top of the line brake controllers. I spoke with the Tekonsha rep and he recommended the Voyager.
The Voyager is a very simple controller, easy to install, and works well. I don't miss the fancy display.

however, the video says the wire butts are included, and they were not.

That video is for a different brake controller, the Prodigy P2 part 90885. The installation will be similar, but not all the same parts are included. The P2 does include a loose wire pigtail and butt connectors. Plug-in connectors and the loose wire pigtail connector are sold separately for the Voyager controller.

Provides braking as advertised. The mount is a bit obtrusive and permanent. If you're looking for a smaller form-factor or the ability to move between vehicles, look at more expensive models.

My brake controller is working great. It is helpful that it is adjustable so the brakes on the trailer can be really aggressive or help out just a little.

by:
This is my second Tekonsha; I had to replace my 10-year old one after I accidentally broke it.

This one is a bit of an upgrade, and is easily able to lock up the disc brakes on my 15,000 lb trailer. Adjusting it properly, I'm able to brake as though there were no trailer at all. Set it, and forget it. It doesn't get any easier than that.

I have traded the vehicle that I installed those products on. While I did have those products they work fine, no problems and they performed as advertised.

The break controller was what I ordered but the wire harness that was sent with it did not have a wiring diagram so I could wire it to my truck correctly. I had to go to a YouTube video to get the correct information so I could wire the harness to my truck without hurting the controller or the vehicle. Question: Does your company not send a diagram with all of your harness? Customer should not have to go to a YouTube video to install the product.

Hi Walter and Donna, since brake controller wiring harnesses are not universal, manufacturers do not provide wiring diagrams in their packages because they do not know how or if your specific vehicle is prepped for a brake controller. However, we do have a help article on brake controller wiring, and general trailer wiring. I have included links for your reference. If you have any other issues do not hesitate to contact our tech experts.

Last year I traded my Silverado for a Yukon to tow my 21’ camper. The hitch tube was integrated into the Yukon bumper and those 20” wheels raised the tube height 7”. I purchased your 13” drop shank to level my hitch/camper connection but experienced trailer “sway” because of that long shank. I fabricated a set of “sway bars” to tame that movement. Now I can tow my camper safely. Thank you for making this long drop shank available for taller tow vehicles!

  • Most Economical Trailer Hitch Receiver and Wiring Harness For a 2023 Honda Pilot Touring
    Our etrailer Trailer Hitch Receiver # e27KR you found is our most economical custom fit receiver for your 2023 Honda Pilot Touring edition. For the wiring you can select from either the 4-Way # C48ZV or the 7-Way # C35ZV depending on the types of trailers you will be towing. If you have a trailer with a 7-way you are also most likely going to need a Trailer Brake Controller # 39510 along with the Wiring # 20127 to connect it.

  • Should Blue Wire From Brake Controller Have Constant Power
    The blue wire coming from the back of your Tekonsha Voyager Brake Controller # 39510 is for brake output to the 7-Way connector.

  • Trailer Brakes Do Not Activate With Brake Pedal When Trailer is Sitting Still
    Actually that is a possibility. Proportional brake controllers will not engage the brakes with the pedal unless the tow vehicle is in motion. Another possibility is the red wire from the brake controller isn't connected correctly. It needs to be connected to the cold side of the stop light switch or the wire that is hot only when the brake pedal is pressed. I would also check any fuses related to towing and replace if necessary. If none of these ideas solves your problem let me know...

    Without knowing what truck you have it's hard for me to know if you have the correct harness. I will say that the problems you are describing are unlike any problems we have ever seen from installing a brake controller. If removing the brake controller makes the problems go away then I would strongly recommend you do so until you figure out why this problem is occurring. Make sure you have your truck shifted into park or neutral before you attempt to start it. You may have moved the shifter...

  • Troubleshooting LED Indicator Light on Tekonsha Voyager Brake Controller 39510
    The green light on the Voyager brake controller # 39510 should come on as soon as you plug the trailer into the vehicle. If it does not come on at all, this indicates that you either have some corrosion inside the trailer or vehicle plugs that is causing a short, or you have a loose power or ground connection. Check the plugs on both sides of the setup for any white or green corrosion. If you see any, clean the plug thoroughly or just replace it. If you don't see any buildup in either...

  • Troubleshooting Voyager Trailer Brake Controller Not Working when Brake Pedal is Pressed
    It is possible that either the connection to the brake switch is no longer good enough to provide an adequate signal to the brake controller and a new connection will need to be made, or there is a short or possibly a bad ground causing the problem. You may want to also check the stoplight fuse. A blown fuse will not allow the signal to get through and the brake controller will not know you are stepping on the brakes. You can find the fuse by checking your owners manual which should have...

  • How to Adjust the Tekonsha Voyager for 35 foot 5th Wheel Trailer
    When you are setting up the braking power for the Tekonsha Voyager # 39510 you want to start off by setting the power (power knob is on the side of the controller) to the 12 o'clock position. With your trailer and truck fully loaded go ahead and drive on dry level pavement at 25 mph and then apply the manual override slide knob (found on the front). You can then adjust the power settings for this controller accordingly. I am attaching a review video for the Tekonsha Voyager as well as...

  • Casita Travel Trailer With Repeated Issues On Left Side Of Axle Only
    Hello Paul. It sounds like you have an axle, or axle mounts that are out of alignment. That is really the only explanation since the issue has been reoccurring even after several replacements. I wonder if the 1st axle sustained damage of some sort which bent the mounts. This would explain the bearings overheating also. At this point I suggest you take your camper to a shop and have them check the alignment of the axles and the mounts.

  • How to Find the Brake Wire on a 2001 Toyota Tacoma for Brake Controller Install
    When we installed a brake controller in a very similar Toyota Tacoma as your (see attached install video), we found that the correct wire to use for the stoplight switch was dark green wire with a white stripe. You should still test this wire for voltage with the circuit tester to verify it is the correct one. But this would be an excellent starting point.

  • Troubleshooting A Tekonsha Voyager Brake Controller That Isn't Sensing The Trailer
    Hi Howard, Typically if the Tekonsha Voyager Trailer Brake Controller # 39510 isn't detecting the trailer it's just an issue with the trailer connectors not making a solid connection. Check the pins on your trailer connector to see if they're corroded, damaged, bent, or dirty. A lot of the time the pins get bent back from connecting to the 7-way socket on the vehicle over and over and just need to be bent back into place with a thin flathead screwdriver so that they contact the pins in...

  • What To Do if an RV Dealership Installs a Brake Controller Incorrectly and Damages Cruise Control
    It sounds like the RV dealership that installed your Tekonsha Voyager Brake Controller part # 39510 did not install the controller correctly initially, and even though he attempted to rewire the controller the damage was done to your vehicle and now you have lost cruise control. I would recommend having the mechanic look at the circuits like you are doing, and then once they confirm that the initial install of the controller screwed up your cruise control circuit I would go back to the...

  • What Hitch do You Recommend for My 2022 Subaru Forester?
    Definitely! The main factors that determine the hitch are hitch receiver opening size (either 1-1/4" or 2"), weight capacity offered, and how the hitch installs on your vehicle. For example, if you are looking for a hitch that is compatible with most accessories and provides you with the most weight capacity, I recommend going with a 2" hitch like the Curt Hitch - 2" # C13409. Not only does this hitch provide you with the most weight capacity we offer for your vehicle (525 maximum tongue...

  • Trailer Wiring Harness Needed to Add 7-Way Connector to 2019 Toyota Highlander
    When it comes to supplying power to the brake lights to your trailer your 2019 Toyota Highlander actually has an existing connector so you don't have to splice into the OEM wiring on your vehicle. To add a 4-Way connector for your basic trailer lights you either need the T-Connector Kit # 56042 if you have the factory tow package or the T-Connector Kit # C56217 if you don't have the factory tow package.

    The particular parts you need to install a fully-functioning 7-Way on your 2019 Toyota Highlander Hybrid will depend on what exactly it's already equipped with. Either way you will need to start by adding a 4-Way connector harness. If your Highlander has the factory tow package I recommend the Curt T-Connector # 56042.

  • Installing 7-Way Trailer Connector on 2019 Ford Ranger With Existing 4-Pole

Once installed, you will have a functional 7-way, and will still retain a functional 4-pole. If the trailer you're planning on towing has brakes, you'll need a functioning brake controller to actuate them. I really like the Brake EVN, part # TK63VR.

  • Solution For Brake Controller EBS/Error Message On 2020 Toyota 4Runner
    This is a common issue I've seen in many different Toyota 4Runners as they seem to be more sensitive to backfeeding from the red wire of the brake controller to the stop light switch. This causes the issue you're seeing, triggering the ABS error message. You are correct when thinking that a diode will prevent this from happening but the Tekonsha 3041-P harness does not feature a diode in the red wire; the harness you need is the # 7865.
