injector harness ?

[87GN 98GTP]

I was told the car had 83lbers and was wandering if theres a way to tell if they are low impedence to require a different harness or its already been done, 1st the harness for the injectors look stock, 2. would I have issues all the time if I needed the better harness for the low impedence ones, im just going through all things to make sure it runs 100% in spring

Give numbers on injs ? The drivers are in injectors or ecm not the harness.
