Rb25 Starter Motor Question

[warpz0r]

Hi all,

which pin on the ecu triggers the starter motor on the little spade connector?

+12v goes from the battery to the starter motor but is there a ground aswell on the starter motor?

thanks

The starter solenoid is triggered by the ign switch 'START' position, but there is a connection to the ECU to tell it that engine start is happening (IOW, the starter isn't triggered by the ECU).

Ground for the starter is via the battery -ve connection to the block (thick cable connected from the negative battery terminal to the block....or should be).
