Mitsubishi Evo VII–IX to Haltech uC-10 Adapter Loom

This adapter loom is designed specifically for connecting a Mitsubishi Lancer Evolution VII–IX to a Haltech uC-10, when used with an aftermarket plug-in ECU or an ECU with a plug-in adapter.

Important: Some inputs are received via CAN. The aftermarket ECU must support transmitting these signals to the Haltech uC-10. The ECU must already have these inputs available or be appropriately wired to receive them.

Functions Retained by the Haltech uC-10

The following functions are supported, provided the vehicle was originally equipped with them and they remain in their original operating condition.

Electrical & Convenience

• Alternator charging and warning

• Park / illumination input

• Indicators

• Door ajar input

• Front / rear fog light input (combined)

Warning Lights & Safety

• Low oil pressure switch input

• ACD mode switch function and light input

• ABS warning light input

• Brake warning light input (low fluid level / handbrake / 4WD control)

• High beam input

• Seatbelt warning input

• Intercooler spray indicator

Engine & Vehicle Data

• Fuel level input

• Engine speed input (via CAN)

• Malfunction indicator light / check engine light (via CAN)

• Engine coolant temperature (via CAN)

• Vehicle speed signal (via CAN)*

Vehicle speed is wired from the original vehicle wiring to the ECU and is used by aftermarket plug-in ECUs and adapter looms.

Original Equipment Functions No Longer Retained

The following factory functions are not supported with this adapter loom:

• SRS warning light input: Installation of an aftermarket steering wheel permanently removes the driver's airbag system.

• Engine oil level warning: We have yet to encounter this function wired and operational on an original Evo VII–IX, and it is absent from many factory wiring diagrams. As a result, this input has been left unused to provide an additional spare input for I/O expansion.
