54GC, you would need to add a relay that gets power when the key is on, not necessarily from the ignition. the other two connectors -one comes directly from the battery the other goes to the elec fuel pump. Should be a picture on the new one.
Relay avail,Aotozone ,Orielly,etc

edit-if your system is 12 VDC
