Folk I am curently installin a manegement system ( almost like a megasquirt)on my eg4 and the only problem I have is that the alternator is not charging. Now I`m not using the ecu anymore so I get no power to the alternator for it to work. I have 3 wires going into that round green plug. Does any one know with one I need to feed 12v so it can start chargin?

white goes to the 80 amp fuse, yellow/black goes to c115 relay then to the 7.5 amp speed sensor/alternator fuse located under the dash, ignition is hot here when key on pos 2... white/green is the alternator signal output from the ecm but i do not know what your going to do here because u are ridding of the oem ecm. it controls load to help with economy. and white/red is another alternator signal wire...
white/blue goes to the under the dash fuse box number 6 i think which is an integrated charging indicator(the one that triggers the battery light).
