Take note of the wire colors at the injector connectors, each one will have 1 wire the same color(power source) and the others will be unique going to the ecu. Write those colors down. The ecu has 3 connectors (harnesses), the large connector is A, the medium size one is connector B, and the small one is C. All 4 injectore wires should be in a row next to each other on the outside edge of the largest connector A, usualy pin numbers 1 3 5 and 7 in a row. You can identify them easily by matching all 4 colors. BTW PR3 is OBD1, and I don't beleive has injector protection diagnostics, so an open circuit may not prevent injector control.
Make sure the connectors dont have any water damage or corrosion, water usualy intrudes an ecu through its connectors.
