Brand: AutoMeter · SKU: 9117 · MPN: 9117 · Category: Components
The AutoMeter 9117 Tachometer Adapter is an essential solution for installing a tachometer on modern vehicles equipped with distributorless ignition systems (DIS), including coil pack and coil-over-plug setups. Since these engines lack a traditional tachometer output or signal wire, this module senses current in the ignition system and converts it into a standard 12-volt square wave signal. This output is compatible with all AutoMeter tachometers and most aftermarket RPM-activated devices. The unit is fully potted and weatherproof, making it durable enough for underhood mounting in harsh environments prone to heat, moisture, and vibration.
