We now offer the MS3-Pro with a drop on wiring harness for LSx motors with the 24X crank trigger. And this isn't just any drop on harness, either - we made every effort to make this one of the highest quality off the shelf drop on harnesses you can buy anywhere. We use a sealed relay and fuse box - not the cheap open fuse blocks we sell for $6.50. We made the power wires big enough to supply a 30 amp fuel pump like an Aeromotive Eliminator - and a 30 amp fan at the same time. The harness is wrapped in TechFlex F6 fire retardant wrap, with heat reflective tape added where it runs near the exhaust, and all points where it branches off use heat shrink tubing for a finished look. The connectors all have heat shrink labels to make routing easier. And we have versions for EV1, EV6, and truck injector connectors.

We're offering these for a special introductory price of $1599 for the entire package - ECU, harness, fuse box, and all.
