Patrol FAQ

FAQ

What should I do with the stock ZD wiring and ECU?

  • The stock ECM must stay in the vehicle. It controls more than just the engine, including the tachometer and air conditioning.

  • It's best to get a wiring diagram and label everything when removing the loom from the motor.

  • Anything not used can be cut and terminated or unpinned from the ECU plug.

Do I need a fancy electric lift pump?

  • AirDog is the best option.

  • Alternatively, you can use an Aeroflow Black lift pump with stock OEM filters.

Will the factory ZD30 radiator work?

  • No.

  • You'll need to swap to a TB45 radiator so the ports are on the correct side.

How do I convert from fly-by-wire to cable throttle?

  • Remove the stock electronic pedal.

  • Replace it with a mechanical pedal from a TD42, TB42, or RD28.

  • Use a pre-made cable and mount it through the stock firewall hole.

Do I need to remove the factory battery box to fit an airbox?

  • No. The standard battery box frame can stay.

  • FFM makes an airbox that fits with the battery tray for driver’s side entry.

  • Alternatively, use a Radius Fab pod box for driver’s side entry with a crossover pipe.

How do I get the tachometer to work?

  • Use your factory tacho sensor and mount it on the balancer.

    • You'll need to add four evenly spaced slots to the balancer to produce the correct signal.

  • Or, tap the alternator and use a Dakota Digital box to correct the pulse signal.

Where do I hook up the heater core lines?

  • Connect them above and below the thermostat housing.

Can I run only the filters on the AirDog pump, or do I need to keep the OEM filters?

  • You can delete the OEM filters.

  • Running all 4 filters will restrict diesel flow and reduce power output.
