Professionally engineered and easy to install, fire up your engine on day one! All wiring is composed of TechFlex woven, self-extinguishing wrapped hi-temp TXL & GXL automotive grade wire with OEM Delphi & TE connectors. Reach the battery under the hood or in the trunk with 4 gauge power & 10 gauge ground wires. 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 MS3Pro ULTIMATE 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 was designed with room to grow! And did we mention it’s show-quality-drop-dead-gorgeous?
This harness also is designed for optional automatic transmission control using the AMP EFI CAN transmission controller; Just plug in our transmission controller using the proper sub-harness (for 4L60E or 4L80E) and you’re ready to control your trans!

The MS3Pro 58x GM LS Plug and Play Harness is configured for a cable operated throttle body. The included connectors are set up for an LS1 style throttle position sensor and IAC valve. Four barrel style or independent throttle body setups may require modifications to the harness.
Note that the alternator connection is designed for high mount alternators such as Corvette and truck setups. Low mount alternator setups, as well as other aftermarket accessory drives that do not have the alternator high on the driver’s side, require our alternator extension cable.
