Electronic controller activates electric trailer brakes with a preset intensity when you apply the brakes in your vehicle. Digital display is simple to read. Power output and braking aggressiveness are easily adjustable. Includes manual override.
Features:
Specs:
The Activator II applies your trailer's brakes when the brake pedal in your tow vehicle is engaged. Every time you apply the brakes in your vehicle, a signal is sent - via the brake switch - to the Activator. The controller then sends power out to your trailer brakes to activate them with an intensity set by you, at a rate determined by you. Both the amount of braking power (output) and rate of application (sync) can be adjusted to suit your preference, the road conditions, type of trailer and size of the load. To determine which levels are best for your application, you must test out your towing setup and choose what feels best.
A time-delay controller is so named because there is a delay between the time that you initially apply the brakes in your tow vehicle and the time that the controller reaches maximum power output. Unlike a proportional brake controller, which activates your trailer's brakes based on the deceleration of your tow vehicle, the Activator sends power out in the same way, with the same gradual delay, no matter the braking situation. Although this delay always exists, it can be adjusted by changing the sync setting.
Sync Settings
To adjust the aggressiveness of your trailer's braking action, use the slide control on the side of the Activator II to change the sync setting. If you want to reach maximum power output faster, move the switch forward. To get smoother braking action, move the switch backward, thus supplying power to the trailer brakes more gradually. You can alter the sync setting to suit your driving preferences or to improve handling based on changing road conditions or varied trailer loads.
Quick, Simple Installation
Because inertia plays no role in the functioning of this controller, you do not have to mount the unit at any particular angle. As a result, mounting options are limitless, so long as you can still easily access the controller.
Installation of the Activator II requires that you either purchase a custom wiring adapter designed to plug into the controller or that you hardwire the controller directly into your vehicle. To hardwire the Activator, you must remove the plug at the end of the integrated wiring harness.
Installation Accessories
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.
Features:
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.

Videos are provided as a guide only. Refer to manufacturer
installation instructions and specs for complete information.
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.

This hand break is exactly what I was looking for. I had one on an old truck that I had sold and wanted to put one in one of my newer trucks. I kind of knew what to expect - what I didn't expect was the exceptional customer service I received from etrailer. I placed my order and the people at etrailer kept me informed on every step of the delivery process up to and including delivery (even what door it was delivered to at my house) Now that's what I call service!! Will definitely use etrailer again!! Thank you31219

I was kept informed on the order, shipment and delivery, and it came right when you said it would. It installed easily in about 1/2 hour. All the tests we did worked well. 30629

Product is simple and strait forward to install. Controls are simple and doesn't take a lot of messing around with to get the hang of. My only gripe is that I wish instead of having self tapping screws to mount to the car, it came with bolts/nuts. That way you don't have a pointy screw protruding out the back of a panel and possibly running through what's behind the panel or rubbing on other wires.78265

Great brake controller. Bought the adapter plug and had it installed and ready to go in the truck in less than 30 mins. Easy to set and adjust. Customer service was great. Needed it shipped to me fast. Called and the lady in customer service made sure it was shipped that day and arrived to me in 2 days. She sent me emails making sure I knew when it shipped. Great company to deal with. Would definitely order from them again. 76020

Installing this into my 2005 Tahoe was a breeze. If you just follow the directions and check out etrailers videos you should have no problem. I went from a small popup to a bigger hybrid so I had to get the EBC system. This sure beats taking it to the RV or Dealer store and paying retail plus labor. Thanks etrailer.com 53924

If you desire a simplistic brake controller with no frills, this is it. It is a good value for the money. The installation instructions are very limited, would not recommend this to be installed by someone needing a lot of instruction help.44619
