LS M150 WIRING LOOM

While it is possible to reuse a fuse block from the donor vehicle, they are often much larger and more complicated than necessary just to serve for this engine harness. What is needed are typically four power fuses and two relays to complete the standalone harness. Understand that this harness is just for engine control and does not necessarily tie into the rest of your vehicle harness.

Such outputs as the speed sensor can be used to drive an aftermarket electronic speedometer and an engine rpm signal that can run a tachometer. Plus, today there are tablet apps that can read and display some gauge information.

Along with building a standalone harness for the engine swap, you will need to have the powertrain control module (PCM) reprogrammed to remove the Vehicle Anti-Theft System (VATS), accommodate a noncomputer-controlled transmission (if used), reset rear axle ratio/tire size for speedometer output, remove emissions functions or rear oxygen sensor inputs for off-road applications, set electric fan control temperatures, and so on.
