The MS3-Pro 24x LS Plug and Play Harness is the highest quality, best value option for LS Motors in the industry today. Save your hard earned time and money while experiencing the virtually limitless feature set of MS3-Pro Engine Management System. Available for EV1 or EV6 Style injectors….
The MS3-Pro LSX Series plug and play harness is professionally engineered and easy to install. Fire up your engine on day one! All relays and fusing live in a single, waterproof fusebox and the fuel pump wiring / relays / fusing is big enough for pumps that can handle 1000whp or more right out of the box (10ga wire, 30amp circuit). Additionally, all of the available I/O of the MS3-Pro are brought out in the harness to make expansion as easy as possible regardless of the featureset you’re planning to use, allowing for killer features like traction control, bump box, table switching, flex fuel, and more.
This harness also is designed for optional automatic transmission control using our MicroSquirt transmission controller (sold separately). Literally just plug in our transmission controller using the proper sub-harness (for 4L60E or 4L80E) and you’re ready to control your trans!
