DDE 5/6 EDC16 Standalone Wiring Harness TDCI

A Wiseman’s Engineering wiring harness designed to make standalone engine wiring easier.

This is for engines using the DDE5/6 ECU, including M57N and M57N2.

Designed for use with a deimobilised ECU, this harness replaces the vehicle body side wiring.

The loom connects to:

• ECU
• Defender TDCI throttle pedal
• OBD port

It has outputs for:

• Oil light
• Inline fuel pump
• CAN BUS (for connecting to 6/8hp gearbox or other CANBUS devices)

It should be noted that the oil light outputs does not always work on this generation of ECUas they are predominantly canbus based. We would therefore recommend wiring these up seperately.

You connect:

• Ignition supply
• Permanent 12v supply
• Battery negative

It does not include the main relay wiring, it is important that this is connected correctly and details can be found in our wiring guide.

Whilst every effort has been made to provide detailed instructions to make the loom as straightforward as possible to fit, it still relies on a reasonable working knowledge of vehicle electrics in order to find and safely connect to power and ground sources. We have included the fitting instructions below to aid your judgement.
