Plug in Harness Adapter for BMW m20 engines with 55pin Motronic 1.1/1.3 Ecu

The factory m20 harness has some very outdated wiring practices and for that reason our adapter brings it up to modern specification by including separate leads for the TPS, the IAT sensor and also a lead for LSU 4.2 Wideband sensor. Adapter houses 2 fuses for ECU and wideband protection. Also included is an inlet air temperature sensor (IAT) and fitting plate for e36 variable TPS that MUST be used for effective tuning and running.

True Plug and Play! No additional wiring or setting up require

Harnesses are made to order and are available for both Classic and Black version ECU

They can be supplied with additional leads for extra sensors and/or boost valve or multi coil ignition. Contact us for prices and further information on customized  options.
