dr13 1 Posted November 2, 2016 Report Share Posted November 2, 2016 I recently picked up an unfinished project for my son and I to work on. Its a 89 GTI with a 92, OBD1, VR6 conversion. The MK 2 is favorite car. It has a megasquirt ECU in it, but there wasn't any paperwork, diagrams or manual. Can anyone point me towards some information, particularly for the harness and wiring. I am new to these management systems and am having issues right out of the gate. Specifically it doesn't appear to have power. At least none of the indicators light up when I turn the key. any assistance or guidance is appreciated. Thanks, Domonic VR6Pete 1 Link to post Share on other sites
