• (1) Mechman Indicator Light Harness H104

This adapter harness is supplied with all Mechman hairpin alternators for 1996-2004 GM Trucks and SUV's. It accepts oval GM alternator plugs and plugs into oval GM alternators. The longer blue wire gets connected to an ignition switched 12V+ source to turn the alternator on and off with ignition, and also prevent the "check battery" light from coming on in the dash. This harness can also be modified and hardwired to ignition 12V+ for engine swap applications where the stock alternator harness is not available.
