Where it says "Pin 37 on DB37", that would normally go to your fuel pump wire coming out of the MS. Your MS has some sort of RPM input wire. Otherwise it is going to have an awfully hard time figuring out when to fire the injectors and ignition. Perhaps you have misinterpreted one of the other wires.
