LS Stepper Adapter Harness
The Link LS Stepper Adapter Harness is a plug-and-play adapter designed to connect a GM LS Idle Air Control (IAC) stepper motor to the Link Terminated LS Engine Harness. Required for cable throttle (drive-by-cable) LS applications, it connects directly to the pre-wired stepper connector on the engine harness, simplifying installation and eliminating the need for additional wiring.
