no output from my 5 pin ecu

If you look at these you will see that the ignition resistor wiring is THE SAME as it was for breaker points, and the 4 pin resistor is that same way for the COIL side on the RIGHT side of the resistor. On the 4 pin resistor wiring, the LEFT side of the resistor ONLY powers the 5 pin box but MOST 5 pin boxes are in reality a FOUR pin box and do not need that wire

There is a wire MISSING in both diagrams. On the top diagram, there should be a wire going to the coil+ side of the resistor, BROWN, that is FACTORY. LEAVE that in place. That is your coil "bypass" circuit, and is what IS SUPPOSED to be in place of the WRONG yellow wire. AGAIN that wire IS FACTORY and it DOES NOT go to the starter relay as the other diagram states
