This adapter harness allows you to use a Haltech ECU Instead of the Toyota ECU without needing to tap-in or rewire your entire engine harness.

Suits: 1998-2006 Toyota 79 Series Land Cruiser FZJ79 with 1FZ-FE (Australia/New Zealand)

Included: Adaptor Harness, Spares Expansion Kit, Online Setup Guide.

Not Included: Haltech ECU

Quality: Tefzel Wire, Felt Tape, Genuine TE & Deutsch connectors, sealed crimp junctions for vibration resistance, Aftermarket Toyota ECU connectors.

Adapter Features:

- Keeps all OE functions (Aircon, Cruise control, Fuel tank select, etc..)

- Provision for future expansion via custom wiring (Coil over plug, boost solenoids, E85, etc..)

- CAN bus expansion (Used for Wideband control, Digital gauges, etc..)

- Boost control PWM signal is added to redundant sensor connector near the OE airbox (This saves running wire through the firewall) Pictures of this connector down below.

Things to keep in mind:

- Due to the limitations of the OE engine wiring, you are limited to the use of semi-sequential injection and wasted spark. (Sequential conversions can be done via custom wiring from the expansion connector provided in the adapter)

- OE ECU immobiliser system will not function, OE immobiliser uses pulsed coding that cannot be used. (immobilising can be done via software once installed)

- FZJ79 models do not have any oxygen sensors, a Haltech WB1 Controller kit will need to be installed to the exhaust system and plugged into the CAN bus expansion connector. (Keep in mind Nexus model ECU's have built in wideband controllers that only require a Haltech oxygen sensor hardware pack to be connected directly to the adapter)

- OE MAP sensor will not be suitable for turbocharged engines, either replace with Haltech 3 Bar Sensor or use Haltech's Internal MAP sensor provided on their ECU's!

- A downloadable base tune is provided, you will require initial setup to be completed by a competent engine tuner and further more tuned on a dyno. (To prevent damage, install and setup should be completed by competent person/s)

Why would I need this adapter?

The main use for these adapters are for turbocharged applications where the OE ECU falls short of capabilities. However, naturally aspirated engines benefit greatly when upgrading to an aftermarket standalone ECU.

N/A Benefits:

- Greatly improved fuel economy.

- Improvements in throttle response.

- Future provision for turbo/supercharging.

- Closed loop Wideband control

Turbo/Supercharged Benefits:

- Unlimited tuning capabilities.

- Advanced engine protection

- Boost control

- The ability to retain/remap all OE functions and switches.

Boost Control Information:

- Boost control can be done via custom wiring from the SPARES connector that is provided free of charge.

OR

- DJT Performance saves you the hassle of running wire through your firewall by utilising some redundant wiring.

Follow the instructions below on how to use this feature:

- The 3 wire variable resistor pot located in front of the OE airbox can be deleted and repurposed to provide signal for a 3 port MAC boost control solenoid.

- Switched 12v supply will need to be provided from elsewhere and is entirely up to the installer. (Customers typically take 12v from pin B+ at the diagnostics plug behind the airbox, it can be de-pinned or spliced/extended out to the Boost Control Solenoid)

Redundant Sensor Connector Pinout:

Pin #	Colour	Connection
1	_____	Not used or needed by Boost Control (ECU Sig Ground)
2	_____	Not used or needed for Boost Control (ECU 5v)
3	_____	Boost Solenoid PWM signal <-- Signal to control Boost Solenoid
