Hi

I am having a bit of trouble understanding Haynes explanation or wiring diagram for the ignition coil setup.
I need to connect the Gotech ECU to the coil but there is no plus or minus sign on the coil, only pin no. 1 and 15.
Reading the Haynes manual is obly making me more confused. Does anyone know whats plus and minus

15 is ignition live (Positive (+) side of the coil) green wire on the standard loom

1 is pulsed earth from ignition ECU (Negative (-) side of the coil) black wire on the standard loom

 

Excellent, why didn´t Haynes just say it like that

Thanks Moonie

It's the other way around.
15 - black - 12V constant when ignition is on.
1 - green - switching ground from control unit, also goes to rev counter etc...
4 - high voltage discharge.
