CoilX RPM Input adapter with Pigtail

New updated product!! Getting a clean RPM signal on an engine is a tricky problem. The signal from the ignition coil is noisy, with multiple signal spikes reaching 400-500 volts. Directly tapping into this signal can cause erratic RPM readings at best, and at worse, damage electronic components. CoilX is a sensor module that converts the RPM signal from the ignition coil trigger wire into a clean 5v logic-level square wave that can be safely handled by the RaceCapture/Pro Timer / RPM input or other electronic devices. The module features an optically isolated circuit with additional filtering, to help prevent false triggers. The 1" x 0.5" compact board is designed to be assembled with heat shrink and bundled in-line with your wiring harness.http://www.autosportlabs.net/CoilX Wiring Information 2 pin connector Red: Coil Signal Black: Ground (External) 3 pin connector Yellow: 5v power Black: Output Red: Ground (data system)
