On a 90 it's between the battery and the engine. This is it with an added lead to go to the switch. Remember though this one only works with the ignition switched off because of how the 12v is routed through the FP1 relay. As the relay is engaged when the ignition key is turn on the 12v via the test lead is pulled away from the fuel pump.
