INTEGRATING WITH CUMMINS DIESEL ENGINE
NVU TECH DEPT. on 28th Mar 2025
Are you working on a installing NVU Gauge on your Cummins diesel?
We have the answers you need, like where to pickup a Tach signal and where to install your new Pressure & Temp Senders as well as Fuel!
Plugging In:
This is as easy as it gets, before we get ahead or ourselves start by plugging into the appropriate ports:
All 5 and 6-guage kits with OLED screens are plugged in the exact same way across the product line. You'll also notice that the sender/function wire is on the same gauge that the 2" gauge is plugged into. (Green fuel sender wire on speedo, fuel gauge plugs into speedo). The plugs and wiring are not interchangeable on the speedo and tach (you can't plug the volt gauge into the speedo for example, it will think its something else)
SPEEDO:
FUEL: B PORT
WATER TEMP: C PORT
NOT USED: D PORT: This means it not used
TACH:
VOLTS: B PORT
OIL PRESS: D PORT
C PORT: NOT USED
Where to located Tach Signal: (Also includes testing for proper signal voltage)
NVU's Diesel Tachometer uses the ORANGE wire as its TACH SIGNAL INPUT. Tachometer signal can be pulled from a Crank Position Sensor, Universal Diesel Tach pickup or using the Stator post off your alternator(may require modification of alternator, check with a local alternator shop to have this added)
Tach Signal Testing:

SPEEDO SIGNAL
Installing and setting up a speed sender is relatively easy, and the wiring is a piece of cake! The hard part is figuring out which setup you have, this post will help with that. Scroll to the section that pertains to your transmission style and read on. Setting up Speedometer sending unit
Temp & Pressure Sender Locations
Volts & Fuel
VOLT gauge is internally monitored, and no additional wiring is required.
FUEL LEVEL is read from your fuel sender in the fuel tank. Our Phoenix Platform gauges have fully programmable, dampened fuel gauges that can work on just about any tank/sender. We have a comprehensive article on how to use, set-up and test fuel senders and gauges RIGHT HERE>>>>
