so as of now im running an obd0 motor/wiring/dsm 450s/resister box etc. converting to a z6 obd1 and have some saturated rc 440s. if i ran these RCs would i have to disconnect the resister box or if i leave it alone it wouldn't be a problem?

 

the RC440 is a high impedence injector. resistor box would need to be removed.

 

so just unplug and im good to go? what happens when or if its left on?

 

you will not get the right voltage signal to the injectors and they will run poorly. unplug the resistor box, and run it like OEM. Tune the car accordingly.
