Part Numbers: 39510, 3050-P
Proportional brake controller can be mounted within a 90-degree vertical range. LED monitor indicates braking action of trailer. Fine-tune power adjustment lets you set braking intensity to suit your towing needs.
With a proportional brake controller, you can get heavy-duty emergency braking, general braking or slow-to-an-idle braking for your trailer automatically. The intensity with which your trailer brakes are activated and the rate at which they are applied are dependent on the deceleration of your tow vehicle. This means that, unlike time-delay controllers - which send the same amount of preset power to your trailer brakes every time - proportional controllers are able to adapt to every braking situation differently. So, if you slam on the brakes in your truck, your trailer brakes will activate with that same extreme intensity. And if you merely slow down as you approach a red light, your trailer will gradually brake in the same manner.
As long as the Voyager controller is mounted properly and is pointed in the direction of travel, it will sense - via an internal inertia sensor - how your tow vehicle brakes. This inertia-based sensor responds to the deceleration of your tow vehicle as you brake by signaling the controller to send out enough power to your trailer brakes so that they are activated with an intensity that matches. The result is uniform braking across your towing setup. No push-pull action - just smooth, proportional braking every time.
Getting the braking power you need for your application is simple with the Voyager. First, set up the controller as indicated in the instructions, making sure that the internal sensor is properly leveled. Then set the overall power by adjusting the power knob while you test out your rig. The power should be just enough to achieve maximum braking without locking up your trailer brakes.
Once you have the overall power set, you can fine-tune the power output by adjusting the sensitivity of the internal sensor. Use the level knob on the side of the Voyager to achieve your desired degree of intensity. Move the knob toward you (clockwise) to delay the power output, creating braking sensitivity that is ideal for lightweight setups. If you are towing a heavy load, you may want the trailer to brake more aggressively to prevent it from pushing your tow vehicle. To get more intense stopping action, turn the level knob away from you (counterclockwise).
On the front of the Voyager there is an LED indicator that is designed to keep you aware of the braking action of your trailer. Typically, this light burns green to indicate that your trailer and tow vehicle are securely connected. When the light is green, only 5 milliamps are being drawn, thus minimizing drain on your vehicle's battery.
As you apply the brakes in your tow vehicle, the LED will change to red. This indicates that power is being sent to the trailer brakes. The light will also burn red whenever you activate the manual override lever.
During installation and setup, this light is used to ensure that the Voyager will be able to function correctly. Proper leveling of the internal sensor is crucial to the operation of this brake controller. When the sensor is level, the LED will change to a shade of orange.
The Voyager is designed to be mounted in your cab at a vertical angle that is between -20 degrees and 70 degrees.
Note: The Voyager must be mounted on a level horizontal (side-to-side) plane and must be lined up with the direction of travel for the internal sensor to function properly.
Once the controller is mounted, you must level the internal sensor. First, set the overall power to maximum using the knob on the side of the controller. Then, while pressing the tow vehicle's brake pedal, adjust the level knob on the other side of the brake controller (this is the same knob that is used to fine-tune the power output) until the LED monitor is a shade of orange.
Installation requires that you either purchase a custom wiring adapter designed to plug into the Voyager or that you hardwire the controller directly into your vehicle. To hardwire the Voyager, you must remove the plug at the end of the integrated wiring harness.
For easier installation, a vehicle-specific wiring adapter is available for most newer trucks and SUVs. One end of the custom adapter plugs into your vehicle, and the other end plugs into the controller - no hardwiring required.
Note: If a custom brake-control wiring adapter is not available for your vehicle, one of the following will be required:
20-Amp circuit breaker (9506P - sold separately) for 2- to 4-brake applications
30-Amp circuit breaker (38630 - sold separately) for 6- to 8-brake applications
See also etrailer.com's exclusive 7- and 4-way brake-control installation kit (ETBC7 - sold separately) if you don't already have a 7-way plug at the back of your vehicle.
Install your electric brake controller quickly and easily with this custom wiring adapter. Simply plug one end of the adapter into your brake controller and then plug the other end into the junction box beneath your vehicle's dashboard.
This adapter plugs into the 6-pin connector on your vehicle's built-in brake control wiring harness. The harness is located underneath the dash, to the left of the steering column, taped to another harness near the emergency brake pedal.
To install your electric brake controller you need to connect the wiring of the controller to your vehicle. Certain manufacturers offer pre-wired options, typically known as tow packages, wherein these wires are run for you from the dash to the trailer connector on the back of your vehicle. Often, a brake controller wiring harness is included with your tow package. This harness plugs into a port beneath your dash and connects to the four wires of the brake controller. If, however, you have a brake controller with a plug in place of the four loose wires, you can use the Tekonsha adapter.
This adapter requires no hardwiring. It is designed to plug directly into your electric brake controller for the simplest installation possible. Because there are no wires to connect, installation is not permanent. You can unplug and remove your brake controller at any time and securely stow it away.

Today in this 2011 Nissan Pathfinder we're going to install part number 39510 from Tekonsha. This isthe Voyager trailer brake controller.This vehicles already been equipped with a 4-pole wiring packaging from the factory. To add ourbrake controller and connector, we're basically going to just fill in the blanks. We're going to start offunderneath the dash. We're going to locate the tow package port underneath the dashboard whichis going to be just right of the steering wheel, behind the dash, and also a little bit above thediagnostic port.We'll go ahead and take the adapter cord and plug it into the brake controller, and then we'll goahead and plug it into the port underneath the dash. The part number for our adapter cord will be3050-P.
With all the brake controller wires plugged together, we'll go ahead and add the bracket tothe dashboard underneath. We're going to locate it next to the diagnostic port, just a little bit to theleft of it. We'll use two screws to attach the bracket to the dashboard.Next we'll pre-drill the holes in our brake controller to accept the hardware; we'll install the brakecontroller to your bracket using four more screws; and then we'll go ahead and take a moment to ziptie our wires and make sure they're safe and out of the way. Then we can go to the back of thevehicle. Thats where we're going to go ahead and add our 7-pole connector to the back of thevehicle.
Thats going to be part number 37185. We're going to take the bracket and hold it to thebottom of the hitch. Theres an existing weld nut we're going to use to fasten it to the hitch. We'llhold it up there, make a mark on the bracket, and then we'll go ahead and drill it out to a 3/8 hole.We'll take our bracket back to the vehicle and attach it to the hitch, using an 8 mm bolt, the 1.25thread hitch; then we'll go and add our 7-pole connector. On the 4-pole end of it we're going toapply some dielectric grease and then attach it to the factory 4-pole.
We're going to run a zip tiethrough the wires to make it a semi-permanent connection. We'll take a moment to tape up ourwires and also add our loom material to help protect some of the wires and make it look nice.At this point we'll go ahead and connect the 7-pole to the bracket, and then we're going to add alength of wire to it about 3 or 4, part number 10-2-1. We'll cut the sheath back and we'll have ablack and a white wire. We'll run our black wire to the black wire on the 7-pole connector and ourwhite wire to the blue wire on 7-pole connector. We'll crimp those down and then use some tape tohelp protect them.There are two remaining wires left.
Therell be a white wire for the ring terminal and a purple wirefor the buck connector. We're going to tape those two wires to our grey cable, and we'll run thosewires along with the grey cable. Now we're going to route our cables over to the end of the towpackage which is located next to the spare tire. We'll measure a length of a grey duplex cable weneed and cut the excess off; then we'll strip back to the sheath of the grey cable, exposing the wireswe'll need later. Then we can take the white wire with your ring terminal and ground it to the frame.The self-tapping screw we'll be using will be part number SA1131822.We're going to look for a connector thats at the end of our tow package. We've got a smallconnector with two wires going to it. There will be a brown wire and a purple wire going to it. Now,we dont have a connector to match that, so well rotate the connector and remove it from thewires; then we'll go ahead and crimp our wires from our grey cable to those two wires. We'll use abuck connector to make those connections. Our part number for our buck connectors we'll be usingwill be part number 05732-2.We're going to connect this as follows. Our white wire which will be our brake controller output isgoing to connect up to the brown wire; and then our other wire, a black wire, will connect up to thepurple wire. Thatll be our 12 volt power supply. We'll go ahead and tape up our connections and ziptie our wires safe and out of the way.All our connections are done at the back of the vehicle; now we'll go underneath the hood and wehave to add one relay to power our 12 volt power supply. Theres a relay box closest to the battery.We'll remove the lid and you'll see that theres two relays already installed, and therell be an opensocket for an additional relay. We'll install the relay for our 12 volt power supply, and thats going tobe part number V38937-1.With all of our connections made, we'll go ahead and test out the brake controller. We'll plug atrailer into it and you'll see that the LED on top will turn from off to a green color; and then we'll usethe manual override. You'll see that goes from a green, to a yellow, to a red that shows the manualoutput works. Now we'll go ahead and try the foot brake. We have to make the level in the brakecontroller a little bit more aggressive, so we can see it work. Push down the brake pedal and you cansee that turns from a green to an orange.And with that, thatll finish it for our install of our Voyager brake controller on our 2011 NissanPathfinder.

Top notch service and sales. Installed in less than 15min and works great. I will never buy anywhere else.88928
by: Richard P.03/01/2011
This installation is in a 2010 Ford F-150 Lariat 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.8161
Installed in 2006 Toyota Sequoia towing 5000 lb camper. Nothing fancy with this brake control unit, but I wanted simplicity. I have exact same unit in 2000 Silverado used for towing 5th wheel camper. 13 years of towing various trailers, never a problem braking, this unit gets it done! Easy to install and set up. Etrailer.com was great, ordered from website, had the unit 3 days later, installed and towing on day 4...Thank you.68653
by: Matt Z06/29/2013
Just as described. I had a four pin and that plugged into this wire harness and then I had two wires to run to front of car. Once under the hood there are a few other wires to run to battery and through fire wall into vehicle to connect to a break controller. My local shops wanted over $400 for parts and labor. I saved over $250 doing it myself. It took me about 3 hours. At least an hour was running wires through the fire wall. The engine compartment was very tight near firewall in my 2006 Toyota Sierra. 86763

I have not used this product for trailer brakes yet as I have not bought my travel trailer. Installing was very easy even without a factory stock plug to connect to. The only problem I had with the unit is there is no way to know if it works until you have a trailer plugged in (or you jump the connections at the plug). I had to hook up to a friends trailer just to know if it worked. Other than that, no complaints.31165
UPS delivered the controller and wiring harness today. I had it installed in my 2006 GMC in less than an hour and it works perfectly. Thanks for getting my order delivered to my door step so timely. Great products and service.92459
by: Greg M.07/30/2013
I have had several of these over the years. I currently have 3 controllers on different trucks. I pull 5 different trailers with completely different weights. The controller works really well. I definately recommend this controller. You level it on the left side, which allows for placement in alot of areas of the truck. When I am towing I can adjust the brakes with the dial on the right side. Obviously the brakes need to be lighter when the trailer is empty. Simply turn the dial back until the brakes don't lock up. When I get it loaded I turn the dial forward until I can feel the brakes take hold. The lever on the front lets me manually apply the trailer brakes. I use this in cases where I am going downhill and it is better to let the trailer slow me down. If I ever need another controller, this will be it. Great price also.92292

I'd had one of these before so ordered for my current install, they're a good controller, however, it's limited to 20º nose down on the install, so it didn't fit my current dash. My mistake, I should have checked before ordering. Decided to order a P3 to replace it, etrailer customer service was awesome, issued an RMA (I hadn't attempted to install it yet, just read the instructions and saw the limitation). I'd deal with this company 100 times out of 100 for my trailer needs!24628
Easy to install and works fine. I was a little confused though. I watched this vied which was extremely helpful and told me exactly how to install the device http://www.etrailer.com/tv-install-brake-controller-2011-chevrolet-suburban-90885.aspx however, the video says the wire butts are included, and they were not. Otherwise, all is good.107567
by: Walter D.10/24/2013
I had already looked at the install video on etrailer. When the controller and the adapter for the Suburban arrived it took 15 minutes to install! Drill two holes, mount controller and connect two plugs. Easiest install I have ever done.104902
by: Patrick Magers05/06/2013
I installed this controller on a 2013 Jeep Grand Cherokee. Installation was easy (as I had also purchased the adapter cable for my Jeep), adjustment instructions were clear and the controller worked perfectly.79126

by: Randy L01/21/2013
Product arrived on time and in good shape. This model Tekonsha is my favorite. I've bought and installed three in the last five years. My philosophy is 'If it ain't broke don't fix it'63744
by: michael flynn08/19/2011
wish i would have known that it didn't come with the pigtail to plug into the plug. so i will have to cut the plug off and use it that way.22301
