I'm installing a mini speedo on my 03 FXD. The instructions for the mini speedo show wire color orange is the 12 volt sensor power, black as ground and green as signal. The actual sensor has wire colors black, red and white. I'm assuming the balck is the ground on the mini speedo but the other two color are different. Does anyone know which ones are which?

 

I would assume that red is hot and white is the trigger wire
