Red wire in USB BDM

[clémentrastoll]

Hi every body,

Sorry in advance for my bad english.

I have kit33812 ECUEVME with USB BDM. But I don't know how to connect USB BDM to ECU. Where should the red wire be plugged into the usb and the ecu?

Thank you so much for your help

The question is a bit vague! The red wire? What red wire?  If you mean the red wire that is part of ECU wire harness that came with the kit you can refer to the manual for the pinout of the ECU wire harness.   I don't know much about car ignition so have no real idea.

If you mean how do you connect the BDM to the board please refer to the user manual available form the product page:

Reference Design MC33812 S12P Engine Control|NXP 

Basically the 6-pin BDM ribbon cable should be connected to the matching 6-pin connector on the board.  The red 'wire' on the connector indicated pin 1 and should be matched with pin 1 on the board.

good luck.

bye
