This is a brand new never used Prodigy RF Proportional Trailer Mounted Braking System model 90250 by Tekonsha. A dash-mounted hardwired brake control isn't necessary with this. It's wireless technology! We bought it because we thought we needed it for our BMW X3. It turns out the X3 has an integrated system in place. Our loss is your gain. It's complete with complete instructions wiring and wireless controller. Still has warranty card too, so you may fill it out as a new purchase. These retail for over $430.00 This is for sale at $275.00 + Shipping. Also available for pick up to save on shipping.
