The Precision Raceworks S58/B58 Plug and Play install harness for the Motiv ReFlex+ is certified by Motiv and a must for anyone adding a ReFlex+ to their S58 or B58 vehicle!

With this harness, there is no cutting, crimping, or splicing of your factory harness, and is 100% reversible if you ever need to return your car to stock! Simply make the appropriate connections and you are done!

What makes the Precision Raceworks Harness different from others?

Simply put, the main harness included with the Motiv Reflex is made very well. The only real downside to the standard Motiv Reflex harness is the sub harness, which requires splicing into the factory wiring. So we made a replacement for the sub harness to make everything plug and play. This saves you a great deal of money when compared to other plug and play options on the market, which ditch the entire harness you are already paying for when you purchase your Reflex Plus controller.
