Electronic controller activates electric trailer brakes with a preset intensity when you apply the brakes in your Chevrolet Suburban. Digital display, manual override, and a simple, plug-in port included. Power output and braking aggressiveness are adjustable.
The Activator III applies your trailer's brakes when the brake pedal in your tow vehicle is engaged. Every time you apply the brakes in your Chevrolet Suburban, 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 III 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. After mounting the unit, hardwire one end of the included pigtail harness directly into your Chevrolet Suburban. The other end plugs into the brake controller.
For even easier installation, a vehicle-specific wiring adapter (sold separately) is available for most newer trucks and SUVs. One end of the custom adapter plugs into your Chevrolet Suburban, and the other end plugs into the controller - no hardwiring required.
Note: If a custom brake-control wiring adapter is not available for your Chevrolet Suburban, 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 Chevrolet Suburban.

Today on this 2006 Chevrolet 3500 Pickup truck we are going to install part number 5520-3015P. This kit consists of the activator three brake controller and the adapter cord to go between the tow package on the pickup truck and the brake controller. The first thing we are going to do is get access to the port for the brake controller and that is behind this panel right here. Remove this nut. There are two snaps on the side of the panel. Undo those and then pull the panel off. This port right here, the second from the left, is the one we need to use. We will take our adapter cord and plug it in right here. Make sure it snaps in and then put the cover back into place. 00:45
Next we will move on to our bracket for the brake controller itself. We are going to mount it to this piece of sheet metal right here. We are going to be using self tapping screws to attach this to since the brake controller comes with screws that are really only good for going into plastic. We will route our cable over to our bracket for the brake controller and we will plug it into the brake controller. These two set screws will hold everything in place. Use a zip tie to hide the wires so they are safe and out of the way. We will check our brake controller now for function. First we will hit on the foot brake. If you see a dot that means you have got connection there. Try the manual override if you have power there too and that is without the trailer hooked up. Now we will hook up a trailer to it and we will check our ratings from there. 01:54
Try the manual override and with the trailer hooked up we have numbers now. Hit the foot brake and we have got numbers too. That means it is working properly. If this is our manual override this activates the brakes by themselves. This is our gain control right here on top and that controls the total output on a scale from one to ten. On the left hand side there is slide switch which is a sync switch. That controls how soon the brakes on the trailer are when you hit your foot brake. When you have it closest to you and you hit the foot brake it cycles through relatively fast. Go the opposite way, all the way to the front of the truck and you can see it is pretty slow going up to full power. With that, that will finish our install for part number 5520-3015P on our 2006 Chevrolet 3500.

great item install was a snap 36165
Brake controller installation It took longer that it should have to connect the controller, but I was being very careful, I would check and then double check to make sure everything was alright. I wanted to do a nice clean job so I took my time. The hardest part was making sure I had the right wire connected for the brake signal to the controller, but even that was not difficult to do. I took some pictures of when I started a task and the end result. I will probably move the controller from the ash tray area at a later date, but for now it is fine where it's at since I don't smoke and I don't let anyone else smoke in my truck. 4920
Let me start by saying etrailer.com is the way to go. There prices even with shipping are about the same, if not cheaper, than a brick and mortar store with a lot more to choose from. Shipping was very fast and everything installed and worked in about 15 minutes. That being said, I'm not real impressed with the brake controller. It's about as basic as it gets. No numerical output reading, just a little red light that is supposed to get brighter the harder you push your brakes. Kind of hard to tell when the sun is out. It does work, and if bare bones is what you want, this would probably work for you. I will be calling or emailing to see about an exchange. I would rather spend an extra $10-20 and get something a little nicer. Will let you know how that goes. 43619
This product was very easy to install. Works like it should. Thanks!!!! 62932
by: Rod radovanovic09/07/2013
The product and instructions are very good. The only reason I did not give an excellent rating is that instruction can be more clear about the ground connection of the unit. I do not think that is necessary to ground the unit all the way to the battery negative terminal (as shown in the wiring chart). It is comber some to do that since another 10 gage wire would need to thread through the engine firewall and rout all the way to the battery. It is sufficient just to use a solid metal underneath the dash and attach it to that location. I have to give a great paradise to the sales people that my unit was shipped on the same day. 98742
Great product. Easy to research and compare to other products on etrailer.com. Easy to buy, prompt shipping, easy to install. Works as advertised. A+++ experience. 109450

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 you 31219
Works awesome very easy install and great service from etrailer !! 100657
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
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
by: Tom O.07/18/2013
I bought this unit with the specific connecting cable for my truck and everything worked just like it was supposed to. It took me about 10 min. to install it once I found the connector in my truck. Also, there are a number of videos on youtube from etrailer.com, one of which showed me exactly how to connect the trailer brake to my specific truck. 90141
by: Paul V.09/04/2012
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
Have yet to use it Fastest installation ever! Took less then 5 min Wiring harness snapped right into place Shipping was lighting quick, ordered it Saturday night received it Thursday with regular shipping....there was even a holiday in between!!!! From this experiance alone I will only buy from e-trailer. 64070

Sir, I recieved the brake controller & wiring harness promptly & the unit was well packaged. Yesterday I installed the controller on my 2002 Ford 150 pickup. Everything went well and the harness plugged right in. Iam very well pleased with the unit & the service I recieved from your company. Many thanks, James 85408
by: K Maconachy01/30/2012
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
by: Dave R.06/04/2012
Product was as described. Installation was a breeze with the included harness. I had it installed and tested in 15 minutes. Shipping was very fast, ordered on Wednesday evening at received it on Saturday. This was my first time using etrailer.com and I will definitely be using them for all my trailer needs. 42764

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

A high quality brake controller. I like the simplicity of a time delay controller. 106802
by: Ed G.12/16/2012
The brake control took about 15 minutes to install. I watch the video for my year and model truck and then installed the unit. It was very easy to install and the adapter worked perfectly. A great product and the best how to do it website I have ever used. 61576
by: Chris S.03/23/2012
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
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
by: Randy Y07/12/2013
watch a video on line about this part. And for once ,something worked like it says it would. I just pluged it in and presto my trailer brakes worked Allso paid extra to have it here in 3 days and sure enough it was here in 3 days 89291
by: Ray K09/16/2011
Website was extremely helpful, video on installation and ordering made things simple. Product was shipped and received promptly and installation was literally a snap, it took longer to find the factory plug then to install this unit. 24058
by: Al S05/27/2013
One of the videos on your website was very helpful to me in locating and accessing the trailer harness plug on my Ford F-150. Once that was accomplished, the installation went very smoothly and the controller is working perfectly. 82054
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
by: Mac C03/12/2014
This product is everything I needed for the tandem Car Hauler I purchased to pull with my 2012 F-150. Etrailer.com was very helpful and responsive to my order. all in all a very pleasant experience. Thank you.. 120367

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

Nice product, easy to use Easy to use an upgrade from my Activator I unit. Has the same manual brake control that failed on the Activator I unit. Hopefully this one does not fail. 2438
by: William J06/29/2013
EASY installation, functions perfectly so far, and like the ability to fine tune brakes depending upon load. Service from etrailer excellent, as has always been my experience. 86734
by: Darrell F.04/25/2012
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
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
by: Eric S.12/21/2012
This is the 2nd truck I have installed this same model controller in and it seemed to work well in the last. Hope this one works as well as the last. 61840
by: Randy D.03/20/2011
Easy to install. simple instructions, I have it wired up but just have not towed anything yet to get the settings set for my application. 9878
