Accel 49365 Accel 300+ Tach Adapter
If your tachometer fails to operate after installing an electronic ignition system in place of the FACTORY points controls you may need a tach adapter. The green lead in the wire harness from the 275+ or 300+ ignition control produces a 12-volt square wave signal. This can be used with most tachometers. If the tachometer still does not function properly you will need a tach adapter. If your tachometer was triggered from the coil negative terminal (voltage trigger) and you are using a the white lead via points electronic ignition amplifier output or OE module to trigger the ACCEL 275+ or 300+ CD ignition control then you need this tach adapter
