The AutoMeter tach adapter for distributorless ignitions is a fully potted, weatherproof module that senses coil current in coil‑per‑cylinder ignition systems and generates a conventional 12V square‑wave tach signal for AutoMeter tachometers and many aftermarket RPM devices. Compatible with 1–12 cylinder engines, it is sealed for underhood mounting and includes wired leads: gray (signal out) 52", black (ground) 24", and red/red‑green (ignition power) 24".
