I have a 93 Lt1. I've got the #1 and #3 injector plugs off the injectors right now. I've lost track of which plug goes to which injector. Is there a way to tell which plug goes where? Are there numbers on the connectors or wire colours? Or does it matter on the 93's with the whole batch fire deal?

 

Pretty sure '93's are batch fire which means all four cylinders on each bank are fired at once per 1 crank revolution, so it should not matter which plug goes where.

 

Also, the connector wiring is normally formed/bent and would follow and fall right where the injector it should connect to would be.
