SwapHelper Tach Adapter – Make Your Tach Work, Period

Dead or bouncing tach after a Cummins swap? This is the fix.

The SwapHelper Tach Adapter converts your Cummins cam/crank signal into a clean, usable RPM signal your truck actually understands. No tone wheels, no extra sensors, no messing around.

Why It Matters

Your tach isn’t just for looks—it affects the following:

• Cruise control

• Charging behavior

• Transmission operation (in some setups)

No signal = things don’t work right.

What You Get

• Works with 12V, 24V & Common Rail Cummins

• Clean, stable RPM output

• Adjustable for different swap setups

• Built specifically for real-world conversions

Bottom Line

If your tach doesn’t work, your swap isn’t finished.

Fix it properly and move on.
