This is a picture of what I have...the Power Plus 20 ignition plug. I view this diagram as looking at the wire side of the plug, so when it is plugged into the ignition switch the purple and pink wires are all the way to the left. During testing I removed all but the red wire and tested for voltage at various terminals on the plug with the key in various positions.
