Why this part
Cobbled wiring introduces noise, intermittent faults, and tuning headaches that cost more to diagnose than the harness itself. This loom is engineered to FAST's own pinout, so signal integrity is consistent from the first start. For a swap or dedicated race build, that reliability is worth considerably more than the price difference over a generic alternative.
