What customers say about "Key Specs"
Tekonsha Primus IQ (90160) Electronic Brake Control
  • 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.
  • You can get these breakers at most auto supply stores. My trailer only has a single braking axle, so 20 amps is plenty, but larger rigs with more brakes might need a 30 amp breaker.
  • For my single axle trailer, I used a 20 Amp circuit breaker (installed next to he main power distribution / fuse block in the engine bay).
  • Pulling an old single axle trailer can be scary. Especially when you have it overloaded. An 18 wheeler passed me doing about 85, I’m doing 55.
  • Used this on a week-long trip towing a single axle camper and worked great.
Tekonsha Prodigy P2 (90885) Electronic Brake Control
  • The inertia response is great, though. Have been using on a 2006 Xterra with a 4200lb camper with dual Dexter axles for 6 months now.
  • My trailer has two axles with brakes and the unit setup and works great. In the mountains, I find that on the fly adjustments are easily accomplished with the large screen and large wheel.
  • Installed in the RV, controls the tandem axle brakes well, easy to install, good instructions.
  • I bought it for my dad to be able to haul a large triple-axle toy hauler trailer with his F-250 diesel and it works like a charm. Easy install and easy to use.
  • Works great, had a short in the break system and this thing detected it, even though it was the wire in the axle. pain to find though.

What customers say about "Features"
Tekonsha Primus IQ (90160) Electronic Brake Control
  • 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.
  • The instructions are clear. Setting the maximum braking level and boost feature are intuitive and simple.
  • Quick easy install. Simple use and LOVE the boost feature!!
  • The boost feature let's me set and forget. I only change boost modes now for driving situations.
  • The boost feature has been beneficial when towing on winding steep mountain roads and on the highway the normal setting works perfectly.
Tekonsha Prodigy P2 (90885) Electronic Brake Control
  • his controller has a boost feature which is handy when loads change. Pulling the single or double PWC trailers does not require any boost, as does the flat trailer when empty.
  • There is also a boost feature (that is adjustable also) on this model.
  • This is a very smart unit. I really like the feature to hold the button down when brake is engaged to go into reverse mode.
  • I bought this one and it is exactly the same just newer and has a feature that if it is turned all the way down when a trailer is plugged in it flashes at you to let you know you have no trailer brakes.
  • It has some additional features such as variable boost control and reverse lock out for backing up. Very nice. As long as it's reliable its a perfect fit to my needs.
