I have a 55 Chev which I wired with the AAW Classic Update harness which has been great to work with. I am adding fuel injection, the primary power leads go directly to the battery however there is a lead from the ECU that must go to "a switched 12V power source that is on for ON and CRANKING, it is critical that the 12V is constant while cranking". What is the BEST place to draw from for this?? Thanks much!
