The Gen 5 LT1 is the latest small block set to replace the LS series of engines which have been around since 1997. With direct injection and VVT, it's a whole new design and we have stayed ahead of the curve by developing a harness package for this new engine. You have all of the familiarity of our 24x and 58x hook-up design for the all new Gen 5 V8! Harness packages are ready to order today! Just like our 24x and 58x offerings, these all new Gen 5 V8 standalone harnesses are built for full function, closed loop control, and designed for use on vehicles seeking to meet local emissions standards (no post-cat O2's, purge canister, or fuel tank evap interface). The standard length of our new harnesses are 3.5 feet. This length is measured from the back of the engine (where the harness forms a single trunk line), to the location of the ECM, and is designed for mounting the ECM inside the cabin area, away from moisture. We support all combinations of Gen 4 LS / Vortec engines with any compatible transmission including LS3 Engine, L99, LS7, LSA, LS9 and 5.3/6.0/6.2 Vortec truck variants, etc. These kits are intended to support all factory emissions control devices that your LS or LT Swap application requires to.

Features:

  • All harnesses include instructions, every wire labeled, and an OBD2 port with integrated check engine light for easy diagnostic checks down the road
  • Built to order - custom main harness that is plug and play with all engine and transmission and emissions control sensors
  • Kits include: engine main harness, transmission main harness, engine ECU, transmissions TCM, EVAP canister, post and pre-cat oxygen sensors, and a compatible drive-by-wire pedal
