Default fuel signal from ecu????

can anyone tell me if the ecu from a 2000 camaro z28 puts out a pos or neg signal to turn on fuel pump? i just found out that it puts out neg signal to turn on fans. by the way i am doing a ls1 swap in my 07 xrunner. trying to get wiring all squared away. thanks for your help guys

Hows this? its 12 volts but remember unless you tune VATS out you will need to feed a sqaure wave form( signal generator to enable the fuel.
