I'm busy with a kill switch installation in a friends car. The only thing I want to find out is which wire of the alternator I have to switch down to switch of the engine. We already know it's not the blue one, but we don't want to cut also the other ones. Does anyone of you know which one we have to take? It's an ODB1 B18c6 engine

 

Car will run even without an alt. as long as batt. has a charge, put the switch on something else, [ground for PGM-FI Main Relay, fuel pump relay control lead from ECU/ECM, a power lead for the PGM-FI Main Relay, power or ground for the ECU/ECM power for distributor assembly]. 94

 

Thats a horrible spot for a kill switch, kill the ground to the fuel pump

 

I've taken ICM1 on the ECU to switch off now, works way better. When I'm home I will make some pictures of the schedule.
