Weatherproof, enclosed fuse block for clean, reliable power distribution
Nylon mesh sheathing throughout for durability and a professional finish
Standard fuel pump wiring
Alternator control wiring included
Full OBD-II diagnostics support
Standard tachometer signal — no adapter needed
Cooling fan control output
Off-the-shelf components for easy serviceability down the road
Important Notes
This harness does not include a gauge cluster connection — it is designed as a standalone engine management harness only.
You will need to reuse your existing fuel injector harness from your stock setup.
