Top is original retrofit with RB ignitor and bottom is with Z32 ignitor. See how the 3 pin plug has wires labelled differently?
Fixed. Technically the original is correct, but the location of 12V and Ground were not same as the plug location. My correction is not pretty but this makes it clearer, I believe. Wires are in same order as bottom diagram with lovely MS paint embellishments...
Ground--Black and purple or black and red wire (opposite side of trigger wire in this 3 pin plug)
12+ --white wire in middle
Trigger wire -- black with 2 silver rings
