GM LS1 Alternator Connector M27500-22SB4T23 thanks to the intuitive setupOEM replacement 4 pin Delco connector for early GM LS series alternators. Suits the Delco CS130D, AD230 and AD244 series alternators as fitted to VX and VY Commodore, Gen III and early Gen IV LS engines. The 4 pin housing uses the P (pulse), L (lamp), F (field) and S (sense) terminal layout, though not all pins are wired in every application. These early alternators use an internal voltage regulator and do not require a PWM signal to charge correctly.
