Tekonsha 90160 Primus IQ Electronic Brake Control

Tekonsha 90160 Primus IQ Electronic Brake Control

A totally proportional electric trailer brake control, the PrimusIQ is self-leveling so no level adjustment is necessary. Utilizing the primary sensor technology from Prodigy, the PrimusIQ now includes the Boost feature that gives users the ability to apply more initial trailer braking when towing heavier trailers.

It works proportionally in reverse for backing into tough spots and includes a snap-in dash mounting clip and removable electrical connector that allows the unit to be quickly stored when not in use. You will appreciate the digital readout depicting a secure electrical connection, amount of voltage delivery to the trailer brakes and diagnostic features incorporated in the LED display.

    If you need an excellent inertia based (accelerometer sensing) electronic brake controller for up to three axles, that can be mounted at angles from 0 through 70 degrees, this is the perfect choice. Frankly, the only reason to buy a higher-end model such as the P3 is if the higher end model provides a feature you specifically need such as stored settings for multiple trailer configurations, 360 degree mount angle, 4-axles, enhanced diagnostics, or electric-over-hydraulic brakes. If you don’t need one of those specific features of the higher-end models, they won’t really provide you with anything compelling above and beyond what this one offers. That is to say, this one provides just as good brake control as models that cost 50% more, and if you don’t need one of the features of those more expensive models, there’s no reason to pay more.After installing, set-up is simple; calibrate the braking pressure per the easy instructions, and you’re set. This setting can be adjusted anytime as brakes age.If your trailer is substantially heavy, choose one of the boost modes. In B1 mode, touching the brakes causes this unit to apply 13% braking immediately regardless of the feedback from the accelerometer. In B2 mode, 25% is applied immediately regardless of the accelerometer. So when descending hills, this enables me to select a mode where the trailer doesn’t wait for the vehicle to start slowing before the brakes start being applied, and this helps to save the tow vehicle’s brakes. I like to use B1 mode with my trailer when I’m descending hills. Other uses of the boost settings are to provide additional control when the trailer is heavy compared to the tow vehicle. B3, for example, is useful for trailers that weigh around 40% more than the tow vehicle, or beyond.Inertia based controllers such as this one are so much better than the less expensive time-delay models. With a time-delay controller, the longer your foot is on the brake, the more pressure is applied to the trailer’s brakes. Time-delay controllers are terrible for panic stops. But they’re also terrible for longer gradual braking; they start out light, and increase force over time. This may not be what you would actually want to have happen. Imagine doing that on a wet road.Inertia based controllers, on the other hand, brake proportionately to the change in momentum of the vehicle. If the vehicle slows more quickly, more force is applied to the trailer’s brakes. So the rate of deceleration controls the braking force of the trailer. That is a much more accurate way to provide braking to the trailer than a “dumb” time delay method.Now here’s why I think this unit hits the sweet spot. Higher priced controllers work exactly the same way. There’s no magic here. Higher priced proportionate controllers work just like this proportionate controller. They just offer more features. And most of those features are only useful for very specific tasks. Someone might pay $150 for a higher-end model, and never need or use the features that model provides beyond this one. Don’t have 4-axles? Don’t need to mount it at 90 degrees? Don’t have hydraulic trailer brakes? Only have one trailer that you tow regularly? Then you won’t benefit from a higher end controller.On the other hand, if you drop below this one in features you typically either get time-delay, or proportionate but with more difficult calibration or no boost modes.This model combines the features that 90% of us need, at a price that 90% of us would be happy to spend.

    Great Brake Controller. I don’t write reviews often but though I need to for this. I replace a very old Tekonsha voyager controller with this Primus IQ and what a difference! Didn’t know brake controllers have come so far with technology. I pull a 24″ goose neck hauling farm equipment (large tractors). Braking is smooth and solid. It works right along with the truck and had to do very little adjusting from having an empty trailer to loaded. The boost setting make it simple to add more braking power when loaded. Being able to have trailer brakes that work while backing up is nice. I live in the mountains and need brakes in both directions. Plus the controller seem to do a good job determining and adjusting to hills. It doesn’t over or under power the brakes when the grade of the road changes.

    Installed this on new 2018 Toyota Tacoma to use with my R-Pod 179. So easy to install. Instructions on line were perfect with the exception of where to put the white ground wire. Once you pull off the kick plate you’ll see a bolt to the lower inside with a connector with other white grounds running to it. Anyway, here’s a picture of where I placed it. Used industrial Velcro to hold it. Picking up the camper from the dealer tomorrow. Setting the voltage looks very easy to. I’ll let you know how it goes.

    This was a really easy install in my 2000 Ford F250 Super Duty with a factory 7 pin plug. It had wiring already in place under the dash, I plugged in the harness 3035-P into each side and I was done with the install inside the truck once I screwed the mounting bracket in place with the provided screws. The trailer brake didn’t light up, so I had to keep looking. What I found was that it is a common issue that these trucks didn’t come with the fuses and relays needed to make the 7 pin plug work properly. I found I needed to install a 30 amp ‘maxi fuse’ under the hood. It was fuse number 28, this powered the trailer brake control circuit. Add maxi fuse #16 (30 amp) for the trailer charging circuit. Then there are two relays that need to be added. They were in a small black box next to the master cylinder, I popped the cover off and there were no relays in there. Those are for the charging circuit and backup lights circuit I believe. Hope this helps someone.

    Cannot say enough about how this makes trailing a heavy load not only easier, but safer! Would never consider towing our closed 26 foot trailer without this again. Made all the difference in the world. Even helped with pushing going down the mountains of Asheville NC which can be a nerve wracking drive. A little bit of playing around with the number to set it on, just drove around town a bit to see what number we would set it to. Slows you and your haul quickly by activating trailer brakes.

    We are “newbies” when it comes to electric trailer brakes and we were pretty clueless when it came to brake controllers. After watching videos of this product and reading other reviews, we chose it because it seemed like it would be easy to set up and wasn’t super expensive. Well, our assumptions proved to be correct…..we had no issues installing and setting it up to work with our vintage travel trailer connected to our Ford F-150. Our camper only weights 1600 pounds and we even contemplated not using the camper brakes at all but after researching the different trailer brake laws in many states, we learned that even though we would be fine in our state without connecting the brakes, we would be in violation of other states that have stricter laws. This controller made the process easy and we also discovered that it was a good idea to utilize our brakes as it has made a big difference in our stopping ability even with a lightweight camper.

    Got this to tow a Bobcat I was renting (they wanted $100 each way for delivery and pickup, or said I could pick it up if I had electronic brake control). Trailer and skid steer weighed over 7,000 pounds. Used a Ram 1500 to tow it. Had never used a brake controller before. Took me all of 30 seconds to setup. Made the towing up and down hills smooth and controlled. No jerking or pushing from the trailer – just smooth braking.Since I will only use this occasionally, I unclipped it from the quick release mounting bracket and put it in the glove compartment. Cable that connects to it is also quick release.

    Proportional controllers are the only way to go… I just put this in my truck and it’s amazing. If you’re still using one of the old/cheap non-porportinal controllers… you need to buy this now. It really works great. You can be just using just a bit of brakes to bleed off some speed and then gradually press down on the peddle and it will gradually increase voltage. It’s quite impressive. It’s easily adjustable and easy to setup. I can set my brakes twice as high as I used to with my old controller and know that if I get in an emergency my trailer is going to put some serious brakes on instantly.

    First, this controller works really well. Now that it’s installed correctly I am very happy with it.I bought an adapter off amazon that plugged into the vehicle and then this unit, for easy installation. The wire bundle had 2 wires inverted, it was for a Honda, not an Acura. I followed some online troubleshooting that had me check the voltage on the blue wire when the brake was not engaged, it should have been 0V but was not. The guide says this means the unit is faulty. Long story short, the black wire is power in, and the blue wire is power out to the trailer. Later I checked the black wire and it was reading 0V. So I switched the two pins and now it works perfectly.I really wish the instructions had a bit more information on wiring that would have made this easier to figure out. Or a step that said, “if your brakes lock, check the voltage on the blue and black wire. Blue should be 0V, black should be ~12V.” Anyways, props to the manufacturer that the unit didn’t break with the wires inverted!

    The unit was very easy to install in my 2014 Nissan Frontier. Mounted with 2 self taping screws. This Tekonsha is very smooth in operation. My old unit was a popular brand, but not near as nice as this unit. The old unit was always jerky in operation no matter how it was adjusted and then it began to work when it wanted to, a bit scary. I tow an 18′ equipment trailer. Sometimes it’s empty and sometime loaded with a diesel tractor. It was very easy to adjust to the varying weights and the “boost” feature is a big plus for me. I love this unit and would buy it again. Don’t forget to get the wiring harness made for your vehicle to make the installation very easy.
