G'day all,

I am wiring in a EMS Stinger 4425 V4 on a 1999 GU TB45 and am unsure of the trigger and home signal wires. There is two wires coming from the trigger wheel sensor on the distributor, Blue and white black. My manual does not indicate which is which and cannot find any info elsewhere - can anyone here who has fitted a piggyback ecu advise?

Thanks!
