LS PWM/STD Alternator & Sensor Pull-Up Controller M27500-20SB3T23 throttle positionLS PWM & STD Alternator & Sensor Pull Up Controller This module does everything the standard LS PWM Alternator Controller does, plus it integrates common pull up resistors required for external ECU sensors. It is designed to simplify wiring when running Holley or similar ECUs that rely on external pull ups for certain inputs. It allows you to: Run a PWM controlled LS alternator without an ECU Or run a standard alternator excite And cleanly wire
