Microsquirt v3 aled and wled wire uses

so I am confused as to if I can or cannot use the wled & aled wires to power the oem injector set up on a vortec 2.2; batch fire isn't my first choice since this could spell trouble if I am to boost the engine. I understand you can use these wires as ignition but nothing on fuel end otherwise they seem to be used for other sensors such as a boost solenoid or a electric fan, etc. I wanted to confirm a yes before I begin building a harness. also i would like to know if the oem 96 2.2 4 wire ignition setup has a sensor ground or not I see that the two wires that go from the ecm to the ignition control a labeled c31 and c32 my best guess is that the ign1 and ign2 wires would be used but I am open to second opinions. thanks in advance the project is a 1988 s10 blazer 4x4 2.2vortec turbo swap
