Budget M57-6 speed automatic DIY wiring harness

M57- 6HP universal stand-alone body harness for all models with 6 speed automatic gearboxes. This wiring harness allows connection of the throttle pedal and OBD port to the engine ECU. It has inputs required by the ECU and outputs for connecting warning lights such as Oil, Alternator and RPM gauge. You can choose to have BMW throttle pedal connector or Land Rover TDCI throttle pedal connector. It has built in CANBUS connection to OBD, ECU and one CANBUS resistor already built in.

This is a DIY wiring harness so you will have to make all gearbox connections yourself. You have to add the gearbox +12v power and ground/earth connections. Join the tails off from our CANBUS in this harness to that in the gearbox harness on your engine and add a resisistor. This will get the gearbox fuctioning and able to drive however to get full fuctioning tip tronic, sports mode, diagnostic’s and start inhibit you will have to research and add all these wires to the gearbox harness.

If you do not feel up to this please find our other complete plug and play automatic harness for the the M57-6hp. This is just a budget option for a serious DIYER!

This is only for engine connection and mainly used in manual gearbox applications. If you required full harness with combined stand a lone harness for the automatic gearbox then please see our other items that suit that application.

** Note for DDE5/6 ECU types other than E53 there is no alternator/charge light output. It is best to use a USB aftermarket digital voltmeter display for charge indication**

Also if you require main body power connector for ECU as seen in the last photo please select this option from the list.
