Tekonsha Primus IQ part # 90160 is our most popular electric trailer brake controller. It's small and fits tight against the dash perfect for mounting it low and out of the way. It has an easy to read digital readout that displays the amount of power being applied. The blue button on top controls a new brake boost feature that allows the braking aggressiveness to be tuned to load size with the push of one button. The kit includes the brake controller, custom flush mount bracket, universal wiring harness, mounting hardware, and complete instructions on how to install and operate it.
