This Idle Air Control Valve adapter harness from FAST allows a newer LS-series IAC motor to be connected to older TPI and EZ 1.0/EZ Fuel multiport harnesses without cutting or splicing. It provides a plug-and-play path to retrofit updated IAC hardware into legacy harnesses, simplifying sensor swaps and preserving the original wiring loom.
