Hi again, hope that you don't mind me you are the most knowledgeable person on these issues. The no.4 on the EEC. green/yel. (pulse/ignition} goes to the - side of the coil. I have 2 green wires on my coil connector.the second wire could to a tach .or ? It has a powerful pulse from it. could I attach this wire somewhere for my Fuel Injectors? will not work by adding to 12V. Thanks for your time on this. Justin
