Introducing the first totally plug-and-play engine harness system to control the Ford 6.2L Boss engine with Holley EFI!
 
Originally found in the 2010 - 2014 Raptor and 2010 - 2022 heavy duty trucks, the 6.2L SOHC Boss engine has been long overlooked for swap and performance applications despite its great potential. The aftermarket is starting to catch up with offerings for this platform, and we've proudly partnered with KP Proformance to make no-hassle, plug-and-play harness solutions a reality.
