Bosch Motronic Me73h4 Pinout DiagramClick Here === the first 26 pins is the Bootstrap of the ECU. If not set the ECU will not boot. Of course, the bootstrap needs to be set to MOTronic BEFORE setting the ECU. The second 26 pins are the harness of the Bosch Motronic. The harness is connected to the ECU through a small connector that is located at the side of the ECU that is exposed when the ECU is installed in the vehicle.The Bosch Motronic ECU set up shown in the picture is a 1.1 and not a 1.3. The pinout diagram does not specify the pins for various features. However, I can observe that the two Bosch Motronic pins 7 and 8 are not connected to anything in the car. My guess is that they are for a future/undecided feature to control antilock Brake System. It is possible that the pins are never connected to anything in the car. It is also possible that they are for some other feature and they are connected to the computer in another way to control that feature.This pinout diagram is for the Bosch Motronic M1.3 (300814 - EMB 8180 - FRD 9A1.12). A lot of other motronic ECU have the same pinout diagram with few exceptions. The pin layout of the Bosch Motronic M1.1 (26216 - EMB 7633 - FRD 6920) is very similar, but this ECU has different pinouts for some parts of the ECU. And of course, the difference between the M1.1 and M1.3 is only 8 pin. The pin layout of all ECU is based on the same engine loom. The pin locations are the same, only the wire-ends (the pins) are moved one connector to the next. Zwei Type B Relays drsfrtbmeyer@gmail.com. So anyway, If you get hold of a Motronic 1.1 ECU from 2002 I would get hold of the Bosch owner's manual before installing it in your vehicle. Otherwise, the Bosch oem support section at Motronic is a very good source of information. [] c8b82c0f98
