2 1/16", 0-4k diesel tach with white LED backlighting.
Our new 2 1/16" diesel tach part number R12505 is built in our factory in Portland, OR.
R12505 features the same font as our EV² series gauges, with LED backlighting for improved visibility at night. This gauge is sold with a bracket and wiring harness; it designed to tie into our magnetic kits (such as R8912) or with our new filter harness part number 9603831. It is designed to work with 2 pulses per rev or less; the tach cannot be hooked up to a mag sensor, alternator, ignition, etc. It will only work with a magnetic sensor kit or filter. Likewise, it cannot be tied into a magnetic sensor.
*For installation in Dodge 91.5 and above, our new filter harness part number R8913 will allow you to wire our tach directly to the factory sensor without R8912-92 tach harness sensor kit part number.*
