P3 BRAKE CONTROL + WIRING HARNESS FOR TOYOTA 4RUNNER, LANDCRUISER, SEQUOIA, TUNDRA TACOMA & LEXUS LX570 GX460 LX470 GX470. CONTROLLER + PLUG/PLAY WIRE KIT.

Super easy to use, works very well. It knows when the trailer brake wire isn't connected, which helped me track down an open connection in my trucks wiring harness. It's small and not really noticeable. I wish the screen could be programmed to turn off completely. Or a power button would be nice. Kind of annoying at night, when not towing anything, but I can dim the screen down to a reasonable level. I also wish it had a light sensor to adjust the screen brightness automatically. The screen can change colors, but some of them flicker constantly, which limits the color choices unless you want to see a flickering screen. Also some of the screen colors aren't even close to the color they are labeled. But these things are minor and don't really affect the operation, which is very good. The manual control know is very useful and easy to regulate.

Installation was great and the harness worked great for my 08 Tundra!

I bought this break controller to install on my 2007 Sequoia. Just got a 27' camper trailer, needed to control the trailer breaks. It was very easy to install, the instructions were very helpful in identifying where the plug connector was on my vehicle. The device plugged right in, wires were long enough, very happy with performance. No trouble stopping with the 7000lb trailer.

Easy to install on '06 Tundra, custom wiring harness fit perfectly, though no extra slack. Routed over the top of the brake fitting and it just reached the existing wiring plug. (Don't forget to remove the plug covering the wiring connector, took me a few minutes to figure that out.) The ground wire needs to be installed as they say the existing wiring isn't quite up to the draw of the braking systems; I found a good ground point near the OEM connector.Set up was easy and I really like the option to set up multiple trailers plus adding Boost. I thought I would set up for loaded and unloaded trailers, but found that setting the brake level for the empty trailer, then adding 1 level of Boost when loaded worked just fine. (1600# trailer plus 2200# Miata)The display is quite bright even when set on the lowest setting, but I've sort of gotten used to it. When I'm done towing for a while, I will probably put a bit of electrical tape over the display.

We used this brake control on a Toyota Tundra to haul a 20 ft enclosed trailer from central Colorado to Austin, Texas. It had to work for driving two mountain passes each way and city traffic. The trailer was loaded with dirt bikes and gear, and was very heavy. It was a solid load for my Tundra to be hauling for those kind of miles over that terrain/roads.I even had to use it on snowy mountain roads and it was excellent.The brake control worked great. It was very easy and clean to install. I would highly recommend any towing vehicle to get a brake control for the wear it will save on your vehicle's brake systems. It is very easy and straightforward to use. It came with good, detailed instructions for installation and use.

This is the first time I've needed a trailer brake controller so I have no reference but since my truck has the brake connector under the dash it took less than an hour to install.I found this type of controller easy to setup plus it has a troubleshooting display I actually used to diagnose a faulty brake connection.Pulling a 9500lb tandem trailer on 800 mile trip including Colorado mountains I had no braking issues at all.

Works great! The only odd thing was that the instructions say the controller will turn off after about 15 minutes after shutting off tow vehicle, however this did not start happening until towing a trailer a couple of times. First time it took about 12 hours for it to shut off. Second time about 2 hours. After this it has been shutting off as stated. I read numerous Internet posts of others having same issue and in some cases it never shuts off. Don't know why this would be, but it will not run the battery down even if it stays on for extended times. Otherwise it's a very easy install (or mine was since my truck is prewired) and it works very well.I mounted mine with a 2x4 piece of industrial Velcro for use with temps up to 140 degrees since there's not many places these days to solidly mount a bracket. I took the little latch piece off the top of the controller that is used with the pocket mount and put the Velcro directly onto the top of the controller. It's more solidly mounted than it would be using the supplied bracket and made it far easier to get to than if I had used the bracket.

I've always used this towing controller on my rigs, and this was the first time I decided to buy on Amazon instead of going to Napa and building my harness as I’ve done in the past. It saved me a lot of time, and it was plug-and-play. A note for other people is that the white wire with an eyelid on it. That is a ground. But the rest is simple.
