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.
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.
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.
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

Tow Ready Replacement Plugin Harness for the Tekonsha P3, Voyager, Prodigy, and Primus Brake Controllers. Also works with Draw-Tite Intella-stop Xtreme, Intella-stop Ultra, Intella-stop Digital and Activator III (5520) brake controllers.

All right, today on this 2001 Chevrolet Express Van were going to install part #: 39523, this is the Tekonsha Power Track brake controller. Now to install this were also going to use part #: ETBC7, the brake controller install kit. Were going to start with that part first. Were going to start off of our wiring harness and start from the rear of the vehicle and work our way up. All right, next well go ahead and take our 7 pole bracket and were going to attach it directly to the bumper. All right, now well go ahead and take our seven to four pole adaptor, well attach it to the bracket, then well take the four pole and connect it to the preexisting four poles on the van.
Well use some dielectric grease to seal the connection up, connect the two four poles together and make a permanent connection out of it. All right, then well continue on with our gray wire and well run that to the front of the vehicle. Now, when we do well make sure stay away from anything moving like the suspension components or anything hot like the exhaust. Now well also take the white wire thats with the gray cable with the ring terminal and well attach that to the frame. Now to attach our ground were going to use a number 14 self-tapping screw.
Now, to run a wire up to the front were actually going to run all the way through the frame. Now, were using a piece of airline tubing to help run the wire through. This also can be a piece of stiff wire or something you can work with. Okay, well pull all the way up to the frame and then well run up through the engine compartment. Again, we want to make sure we stay away from anything moving or that gets hot like the exhaust.
Well run it up along the firewall and pull it out the top and then well use a zip tie to help secure the wire and take up the tension. Next well go ahead and install our circuit breakers. Were going to mount them to the inside of the fender well next to the battery. Now well take our duplex cable and well peel away the gray sheath. Our black wire will go on across the front of the vehicle to the 40 amp circuit breaker for a hot lead.
Then our wire well pull back and leave it out of the way for now. After we have our initial hook up to the circuit breaker well go ahead and take our white wire and then well pull it from the inside out. Now, on this vehicle theres a grommet thats missing in the firewall, so were going to use that hole to run our wires through. If there was a grommet there we would make a hole in the grommet and then run our wires through it. Now, since that weve ran out of cable on our install due to the way how we ran the wire from to rear and the lengths were going to add another piece of cable to it. Well use a ten foot length of wire, were using part #: 10-2-1. Well take this new length of wire and well run it from our 20 amp circuit breaker to the inside of the cabin to where were going to install our brake controller. Now, our black wire will be connected to the 20 amp circuit breaker and our white wire in this bundle will be attached to the factory ground. Okay, now that weve run our wires inside well go ahead and cut them to the length that we need. Then we can go ahead installing the wire harness for the brake controller. Now the wire harness were going to use is universal brake controller plug part #: 20127. Now, we hook up our wires, were going to start with our single white wire. Well connect that to the blue wire on our brake controller harness, then next well go to the gray cable with the black and white wires, well connect those color for color from the brake controller harness and our red wire well run up to the coal side of the brake switch. All right, at this point we can go ahead and start installing the brake controller. Well take our bracket and mount it to the bottom of the dash. Then well go ahead and take the brake controller and well get ready to install it to the bracket. Well go ahead and take one of the attachment screws and make some threads before we attach the brake controller to the bracket. Okay, well go ahead and attach it to the bracket. Well connect our wire plugs together and well zip tie the wires out of the way and well go back underneath the hood and make our final connection. Now, well run two wires to our power supply, one for the brake controller and one for the 40 amp circuit breaker for the 12 volt power supply out back. Normally you want to make your connections straight to the battery. However, due to the lack of room inside the engine compartment, with the battery, we cant really use battery extenders or post extenders. Okay, with our power hooked up well go ahead and attach the trailer to the vehicle and test the brake controller. Now, you can see we have a little green light on the LED. If we move the manual override over you can see how it turns to the green, to orange, to red and it also, since its a time delay brake controller, itll do the same thing when we hit the brake pedal. Okay, and with that, thatll finish it for our install of part #: 39523 from Tekonsha on our 2001 Chevrolet Express Van.

The Product was easily to find on your site. I was able to browse controllers specifically for my truck. The controller arrived as expecteed. 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
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

This is the second Activator II controller I've ordered/installed from e-Trailer. It took considerably less time than you state on your website. My experience with this product has been great and I would recommend it to anyone needing a break controller.34866

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
by: Dan M.04/29/2013
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

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

Break controller works perfect. I also bought a 7 way as my truck didn't have one installed only a 4pole. Ordered the etcb7 kit but didn't wait for it to come went to local hardware store and automotive store and bought the wire and breakers had it all wired in a few hours( weather wouldn't cooperate) 80128
My 2004 Chevy was equipped with trailer towing, so I ordered this controller with the harness made for my pickup. I could not believe how simple it was to install! I put it to use with my camper and it works flawlessly.40899

Excellent product. 12166
The item appears to be well made and as expected. I'm having some difficulties, but with my camper, not with the unit. Probably not a really useful review.10133
by: Brett D01/25/2011
Had the same controller for years, it has worked well. I pull a 4 axle 24,000 # trailer with disc brakes on all four axles. simple, reliable, and inexpensive.6083
Love the digital display! Digital display is now a requirement when I order a brake controller. It is amazing how much better brake control I have knowing before hand how much brake will be applied.2017

Great Product, VERY Easy to install. The only thing I would change is the length of the pig tail. The short length of the pigtail limits your options of product placement.38289

by: Tim S.06/18/2012
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
plug n play made it easy make sure to order harness to fit your auto 20 minutes a d I was pulling trailer to test controller out worked perfect shipping fast AAA service and product very satisfied 107764
